• Using SDL Tridion 2011 Core Service to create Components programatically

  - by user1428019

  I have seen some of the questions/answers related to this topic here, however still I am not getting the suggestion which I want. So I am posting my question again here, and I would be thankful for your valuable time and answers. I would like to create “Component, Page, SG, Publication, Folders “ via programmatically in SDL Tridion Content Manager, and later on, I would like to add programmatically created components in Page and attach CT,PT for that page, and finally would like to publish the page programmatically. I have done these all the activities in SDL Tridion 2009 using TOM API (Interop DLL's), and I tried these activities in SDL Tridion 2011 using TOM.Net API. It was not working and later on I came to know that, TOM.Net API will not support these kinds of works and it is specifically only for Templates and Event System. And finally I came to know I have to go for Core services to do these kinds of stuffs. My Questions: When I create console application to create component programmatically using core service, what are the DLL’s I have to add as reference? Earlier, I have created the exe and ran in the TCM server, the exe created all the stuffs, can I used the same approach using core services too? Will it work? Is BC still available or Core Service replaced BC? (BC-Business Connector) Can anyone send some code snippet to create Component/Page (complete class file will be helpful to understand better) Thanks Jai

• Tikz: horizontal centering of group of nodes

  - by mindhex

  Hi, I need to align each row of the graph to the center. I am trying to do it with xshift. Here the code: \begin{tikzpicture}[node distance=1.5cm, auto, text centered] \tikzstyle{every node}=[draw,ball,align=center]; \begin{scope}[xshift=1.5cm] \node (A) {A}; \node [right of=A] (B) {B}; \node [right of=B] (C) {C}; \node [right of=C] (D) {D}; \end{scope} \begin{scope}[yshift=-1.5cm] \node (AB) {AB}; \node [right of=AB] (AC) {AC}; \node [right of=AC] (AD) {AD}; \node [right of=AD] (BC) {BC}; \node [right of=BC] (BD) {BD}; \node [right of=BD] (CD) {CD}; \end{scope} \begin{scope}[yshift=-3cm,node distance=2cm,xshift=1cm] \node (ABC) {ABC}; \node [right of=ABC] (ABD) {ABD}; \node [right of=ABD] (ACD) {ACD}; \node [right of=ACD] (BCD) {BCD}; \end{scope} \begin{scope}[xshift=4cm, yshift=-4.5cm, node distance=2cm] \node (ABCD) {ABCD}; \end{scope} \end{tikzpicture} Is there any other way to do it? Do not like to change xshift values every time.

• Rails form with a better URL

  - by Sam

  Wow, switching to REST is a different paradigm for sure and is mainly a headache right now. view <% form_tag (businesses_path, :method => "get") do %> <%= select_tag :business_category_id, options_for_select(@business_categories.collect {|bc| [bc.name, bc.id ]}.insert(0, ["All Containers", 0]), which_business_category(@business_category) ), { :onchange => "this.form.submit();"} %> <% end %> controller def index @business_categories = BusinessCategory.find(:all) if params[:business_category_id].to_i != 0 @business_category = BusinessCategory.find(params[:business_category_id]) @businesses = @business_category.businesses else @businesses = Business.all end respond_to do |format| format.html # index.html.erb format.xml { render :xml => @businesses } end end routes map.resources What I want to to is get a better URL than what this form is presenting which is the following: http://localhost:3000/businesses?business_category_id=1 Without REST I would have do something like http://localhost:3000/business/view/bbq bbq as permalink or I would have done http://localhost:300/business_categories/view/bbq and get the business that are associated with the category but I don't really know the best way of doing this. So the two questions are what is the best logic of finding a business by its categories using the latter form and number two how to get that in a pretty URL all through RESTful routes in Rails.

• Starting Beyond Compare from the Command Line

  - by Logan

  I have Beyond Compare 3 installed at; "C:\Program Files\Beyond Compare 3\BCompare.exe" and Cygwin; "C:\Cygwin\bin\bash.exe" What I would like is to be able to use a command such as; diff <file1> <file2> into the Cygwin shell and to have the shell fork a process opening the two files in beyond compare. I looked at the Beyond Compare Support Page but I'm afraid It was too brief for me. I tried copying the text verbatim (apart from path to executable) to no avail; Instead of using a batch file, create a file named "bc.sh" with the following line: "$(cygpath 'C:\Progra~1\Beyond~1\bcomp.exe')" `cygpath -w "$6"` `cygpath -w "$7"` /title1="$3" /title2="$5" /readonly Was I supposed to replace cygpath? I get a 'Command not found' error when I enter the name of the script on the command line. gavina@whwgavina1 /cygdrive $ "C:\Documents and Settings\gavina\Desktop\bc.sh" bash: C:\Documents and Settings\gavina\Desktop\bc.sh: command not found Does anyone have Beyond Compare working as I have described? Is this even possible in a Windows environment? Thanks in advance!

• power and modulo on the fly for big numbers

  - by user unknown

  I raise some basis b to the power p and take the modulo m of that. Let's assume b=55170 or 55172 and m=3043839241 (which happens to be the square of 55171). The linux-calculator bc gives the results (we need this for control): echo "p=5606;b=55171;m=b*b;((b-1)^p)%m;((b+1)^p)%m" | bc 2734550616 309288627 Now calculating 55170^5606 gives a somewhat large number, but since I have to do a modulooperation, I can circumvent the usage of BigInt, I thought, because of: (a*b) % c == ((a%c) * (b%c))%c i.e. (9*7) % 5 == ((9%5) * (7%5))%5 => 63 % 5 == (4 * 2) %5 => 3 == 8 % 5 ... and a^d = a^(b+c) = a^b * a^c, therefore I can divide b+c by 2, which gives, for even or odd ds d/2 and d-(d/2), so for 8^5 I can calculate 8^2 * 8^3. So my (defective) method, which always cut's off the divisor on the fly looks like that: def powMod (b: Long, pot: Int, mod: Long) : Long = { if (pot == 1) b % mod else { val pot2 = pot/2 val pm1 = powMod (b, pot, mod) val pm2 = powMod (b, pot-pot2, mod) (pm1 * pm2) % mod } } and feeded with some values, powMod (55170, 5606, 3043839241L) res2: Long = 1885539617 powMod (55172, 5606, 3043839241L) res4: Long = 309288627 As we can see, the second result is exactly the same as the one above, but the first one looks quiet different. I'm doing a lot of such calculations, and they seem to be accurate as long as they stay in the range of Int, but I can't see any error. Using a BigInt works as well, but is way too slow: def calc2 (n: Int, pri: Long) = { val p: BigInt = pri val p3 = p * p val p1 = (p-1).pow (n) % (p3) val p2 = (p+1).pow (n) % (p3) print ("p1: " + p1 + " p2: " + p2) } calc2 (5606, 55171) p1: 2734550616 p2: 309288627 (same result as with bc) Can somebody see the error in powMod?

• GRUB doesn't recognize partitions on one harddisk

  - by knizz

  I have a dualboot computer with Windows Vista (on hd0) and Ubuntu 9.10. The bootloader is GRUB and the windows bootloader lets me decide between Vista and Ubuntu-Installation (broken WuBi). But now (i don't know why that changed) I can't use start the windows-bootloader anymore. I tried "ls" on the grub-prompt and it gave me a list like: (hd0) (hd1) (hd1,0) (hd1,1) (hd1,2) ... (fd0) It recognizes all partitions of hd1 (the ubuntu-harddisk) but not of hd0(the win-disk). .. WHY?

  Screnario: [internal_server_1]AA------AB[firewall_1]AC----+ 10.2.0.3-^ ^-10.2.0.2 | internet 10.3.0.3-v v-10.3.0.2 | [internal_server_2]BA------BB[firewall_2]BC----+ Ports AC,BC has valid internet addresses. All systems run linux and have root acces to all. Need securely rsync internal_server_1:/some/path into internal_server_2:/another/path My idea is make ssh secure tunnel between two firewalls, e.g. from firewall_1 firewall1# ssh -N -p 22 -c 3des user2@firewall_2.example.com -L xxx/10.3.0.3/xxxx and after will run rsync from internal_server_1 somewhat like: intenal1# rsync -az /some/path [email protected]:/another/path I don't know how to make a correct ssh tunnel for rsync (what ports need tunnel) and to where i will make the rsync? (remote comp address in case of ssh tunnel) Any idea or pointer to helpfull internet resource for this case? thanx.

  A Brief Introduction on Migrating to an Oracle-based Cloud Environment | Tom Laszewski "Before you can start migrating to the cloud, you must define what the cloud means to you," says Tom Laszeski. "The cloud is not a specific software or hardware product; contrary to what many technology vendors would have you believe." Custom Exception Registration for ADF BC EO Attribute | Andrejus Baranovskis "Sometimes customers prefer to implement business logic validation completely in Java, without using ADF BC declarative/Groovy validation rules," says Oracle ACE Director Andrejus Baranovskis. "Thats fine, we can code business logic validation in ADF and implement different custom validation methods on VO/EO level."

• Strange behaviour when simply adding strings in Lazarus - FreePascal

  - by linkcharger

  The program has several "encryption" algorithms. This one should blockwise reverse the input. "He|ll|o " becomes "o |ll|He" (block length of 2). I add two strings, in this case appending the result string to the current "block" string and making that the result. When I add the result first and then the block it works fine and gives me back the original string. But when i try to reverse the order it just gives me the the last "block". Several other functions that are used for "rotation" are above. //amount of blocks function amBl(i1:integer;i2:integer):integer; begin if (i1 mod i2) <> 0 then result := (i1 div i2) else result := (i1 div i2) - 1; end; //calculation of block length function calcBl(keyStr:string):integer; var i:integer; begin result := 0; for i := 1 to Length(keyStr) do begin result := (result + ord(keyStr[i])) mod 5; result := result + 2; end; end; //desperate try to add strings function append(s1,s2:string):string; begin insert(s2,s1,Length(s1)+1); result := s1; end; function rotation(inStr,keyStr:string):string; var //array of chars -> string block,temp:string; //position in block variable posB:integer; //block length and block count variable bl, bc:integer; //null character as placeholder n : ansiChar; begin //calculating block length 2..6 bl := calcBl(keyStr); setLength(block,bl); result := ''; temp := ''; {n := #00;} for bc := 0 to amBl(Length(inStr),bl) do begin //filling block with chars starting from back of virtual block (in inStr) for posB := 1 to bl do begin block[posB] := inStr[bc * bl + posB]; {if inStr[bc * bl + posB] = ' ' then block[posB] := n;} end; //adding the block in front of the existing result string temp := result; result := block + temp; //result := append(block,temp); //result := concat(block,temp); end; end; (full code http://pastebin.com/6Uarerhk) After all the loops "result" has the right value, but in the last step (between "result := block + temp" and the "end;" of the function) "block" replaces the content of "result" with itself completely, it doesn't add result at the end anymore. And as you can see I even used a temp variable to try to work around that.. doesnt change anything though.

• Elfsign Object Signing on Solaris

  - by danx

  Elfsign Object Signing on Solaris Don't let this happen to you—use elfsign! Solaris elfsign(1) is a command that signs and verifies ELF format executables. That includes not just executable programs (such as ls or cp), but other ELF format files including libraries (such as libnvpair.so) and kernel modules (such as autofs). Elfsign has been available since Solaris 10 and ELF format files distributed with Solaris, since Solaris 10, are signed by either Sun Microsystems or its successor, Oracle Corporation. When an ELF file is signed, elfsign adds a new section the ELF file, .SUNW_signature, that contains a RSA public key signature and other information about the signer. That is, the algorithm used, algorithm OID, signer CN/OU, and time stamp. The signature section can later be verified by elfsign or other software by matching the signature in the file agains the ELF file contents (excluding the signature). ELF executable files may also be signed by a 3rd-party or by the customer. This is useful for verifying the origin and authenticity of executable files installed on a system. The 3rd-party or customer public key certificate should be installed in /etc/certs/ to allow verification by elfsign. For currently-released versions of Solaris, only cryptographic framework plugin libraries are verified by Solaris. However, all ELF files may be verified by the elfsign command at any time. Elfsign Algorithms Elfsign signatures are created by taking a digest of the ELF section contents, then signing the digest with RSA. To verify, one takes a digest of ELF file and compares with the expected digest that's computed from the signature and RSA public key. Originally elfsign took a MD5 digest of a SHA-1 digest of the ELF file sections, then signed the resulting digest with RSA. In Solaris 11.1 then Solaris 11.1 SRU 7 (5/2013), the elfsign crypto algorithms available have been expanded to keep up with evolving cryptography. The following table shows the available elfsign algorithms: Elfsign Algorithm Solaris Release Comments elfsign sign -F rsa_md5_sha1   S10, S11.0, S11.1 Default for S10. Not recommended* elfsign sign -F rsa_sha1 S11.1 Default for S11.1. Not recommended elfsign sign -F rsa_sha256 S11.1 patch SRU7+   Recommended ___ *Most or all CAs do not accept MD5 CSRs and do not issue MD5 certs due to MD5 hash collision problems. RSA Key Length. I recommend using RSA-2048 key length with elfsign is RSA-2048 as the best balance between a long expected "life time", interoperability, and performance. RSA-2048 keys have an expected lifetime through 2030 (and probably beyond). For details, see Recommendation for Key Management: Part 1: General, NIST Publication SP 800-57 part 1 (rev. 3, 7/2012, PDF), tables 2 and 4 (pp. 64, 67). Step 1: create or obtain a key and cert The first step in using elfsign is to obtain a key and cert from a public Certificate Authority (CA), or create your own self-signed key and cert. I'll briefly explain both methods. Obtaining a Certificate from a CA To obtain a cert from a CA, such as Verisign, Thawte, or Go Daddy (to name a few random examples), you create a private key and a Certificate Signing Request (CSR) file and send it to the CA, following the instructions of the CA on their website. They send back a signed public key certificate. The public key cert, along with the private key you created is used by elfsign to sign an ELF file. The public key cert is distributed with the software and is used by elfsign to verify elfsign signatures in ELF files. You need to request a RSA "Class 3 public key certificate", which is used for servers and software signing. Elfsign uses RSA and we recommend RSA-2048 keys. The private key and CSR can be generated with openssl(1) or pktool(1) on Solaris. Here's a simple example that uses pktool to generate a private RSA_2048 key and a CSR for sending to a CA: $ pktool gencsr keystore=file format=pem outcsr=MYCSR.p10 \ subject="CN=canineswworks.com,OU=Canine SW object signing" \ outkey=MYPRIVATEKEY.key $ openssl rsa -noout -text -in MYPRIVATEKEY.key Private-Key: (2048 bit) modulus: 00:d2:ef:42:f2:0b:8c:96:9f:45:32:fc:fe:54:94: . . .

[omitted for brevity] . . . 06:f9:ed:b4 Secure storage of RSA private key. The private key needs to be protected if the key signing is used for production (as opposed to just testing). That is, protect the key to protect against unauthorized signatures by others. One method is to use a PIN-protected PKCS#11 keystore. The private key you generate should be stored in a secure manner, such as in a PKCS#11 keystore using pktool(1). Otherwise others can sign your signature. Other secure key storage mechanisms include a SCA-6000 crypto card, a USB thumb drive stored in a locked area, a dedicated server with restricted access, Oracle Key Manager (OKM), or some combination of these. I also recommend secure backup of the private key. Here's an example of generating a private key protected in the PKCS#11 keystore, and a CSR. $ pktool setpin # use if PIN not set yet Enter token passphrase: changeme Create new passphrase: Re-enter new passphrase: Passphrase changed. $ pktool gencsr keystore=pkcs11 label=MYPRIVATEKEY \ format=pem outcsr=MYCSR.p10 \ subject="CN=canineswworks.com,OU=Canine SW object signing" $ pktool list keystore=pkcs11 Enter PIN for Sun Software PKCS#11 softtoken: Found 1 asymmetric public keys. Key #1 - RSA public key: MYPRIVATEKEY Here's another example that uses openssl instead of pktool to generate a private key and CSR: $ openssl genrsa -out cert.key 2048 $ openssl req -new -key cert.key -out MYCSR.p10 Self-Signed Cert You can use openssl or pktool to create a private key and a self-signed public key certificate. A self-signed cert is useful for development, testing, and internal use. The private key created should be stored in a secure manner, as mentioned above. The following example creates a private key, MYSELFSIGNED.key, and a public key cert, MYSELFSIGNED.pem, using pktool and displays the contents with the openssl command. $ pktool gencert keystore=file format=pem serial=0xD06F00D lifetime=20-year \ keytype=rsa hash=sha256 outcert=MYSELFSIGNED.pem outkey=MYSELFSIGNED.key \ subject="O=Canine Software Works, OU=Self-signed CA, CN=canineswworks.com" $ pktool list keystore=file objtype=cert infile=MYSELFSIGNED.pem Found 1 certificates. 1.

[omitted for brevity] . . . af:01:5f:af:ad:6a:09:bf Step 2: Sign the ELF File object By now you should have your private key, and obtained, by hook or crook, a cert (either from a CA or use one you created (a self-signed cert). The next step is to sign one or more objects with your private key and cert. Here's a simple example that creates an object file, signs, verifies, and lists the contents of the ELF signature. $ echo '#include <stdio.h>\nint main(){printf("Hello\\n");}'>hello.c $ make hello cc -o hello hello.c $ elfsign verify -v -c MYSELFSIGNED.pem -e hello elfsign: no signature found in hello. $ elfsign sign -F rsa_sha256 -v -k MYSELFSIGNED.key -c MYSELFSIGNED.pem -e hello elfsign: hello signed successfully. format: rsa_sha256. signer: O=Canine Software Works, OU=Self-signed CA, CN=canineswworks.com. signed on: October 17, 2013 04:22:49 PM PDT. $ elfsign list -f format -e hello rsa_sha256 $ elfsign list -f signer -e hello O=Canine Software Works, OU=Self-signed CA, CN=canineswworks.com $ elfsign list -f time -e hello October 17, 2013 04:22:49 PM PDT $ elfsign verify -v -c MYSELFSIGNED.key -e hello elfsign: verification of hello failed. format: rsa_sha256. signer: O=Canine Software Works, OU=Self-signed CA, CN=canineswworks.com. signed on: October 17, 2013 04:22:49 PM PDT. Signing using the pkcs11 keystore To sign the ELF file using a private key in the secure pkcs11 keystore, replace "-K MYSELFSIGNED.key" in the "elfsign sign" command line with "-T MYPRIVATEKEY", where MYPRIVATKEY is the pkcs11 token label. Step 3: Install the cert and test on another system Just signing the object isn't enough. You need to copy or install the cert and the signed ELF file(s) on another system to test that the signature is OK. Your public key cert should be installed in /etc/certs. Use elfsign verify to verify the signature. Elfsign verify checks each cert in /etc/certs until it finds one that matches the elfsign signature in the file. If one isn't found, the verification fails. Here's an example: $ su Password: # rm /etc/certs/MYSELFSIGNED.key # cp MYSELFSIGNED.pem /etc/certs # exit $ elfsign verify -v hello elfsign: verification of hello passed. format: rsa_sha256. signer: O=Canine Software Works, OU=Self-signed CA, CN=canineswworks.com. signed on: October 17, 2013 04:24:20 PM PDT. After testing, package your cert along with your ELF object to allow elfsign verification after your cert and object are installed or copied. Under the Hood: elfsign verification Here's the steps taken to verify a ELF file signed with elfsign. The steps to sign the file are similar except the private key exponent is used instead of the public key exponent and the .SUNW_signature section is written to the ELF file instead of being read from the file. Generate a digest (SHA-256) of the ELF file sections. This digest uses all ELF sections loaded in memory, but excludes the ELF header, the .SUNW_signature section, and the symbol table Extract the RSA signature (RSA-2048) from the .SUNW_signature section Extract the RSA public key modulus and public key exponent (65537) from the public key cert Calculate the expected digest as follows:     signaturepublicKeyExponent % publicKeyModulus Strip the PKCS#1 padding (most significant bytes) from the above. The padding is 0x00, 0x01, 0xff, 0xff, . . ., 0xff, 0x00. If the actual digest == expected digest, the ELF file is verified (OK). Further Information elfsign(1), pktool(1), and openssl(1) man pages.

• What is the RSA SecurID packet format?

  - by bmatthews68

  I am testing a client application that authenticates using RSA SecurID hardware tokens. The authentication is failing and I am not finding any useful information in the log files. I am using Authentication Manager 8.0 and the Java SDK. I have a traffic capture which I would like to analyze with Wireshark to and from port 5500 on the authentication agent. But I can't find the packet format searching the internet or on the the RSA SecurCare knowledge base. Can anybody direct me to the packet format? Here is an extract from the rsa_api_debug.log file which dumps the UDP payload of the request and the response: [2013-11-06 15:11:08,602] main - b.a():? - Sending 508 bytes to 192.168.10.121; contents: 5c 5 0 3 3 5 0 0 2 0 0 0 0 0 1 ea 71 ee 50 6e 45 83 95 8 39 4 72 e 55 cf cc 62 6d d5 a4 10 79 89 13 d5 23 6a c1 ab 33 8 c3 a1 91 92 93 4f 1e 4 8d 2a 22 2c d0 c3 7 fc 96 5f ba bf 0 80 60 60 9d 1d 9c b9 f3 58 4b 43 18 5f e0 6d 5e f5 f4 5d df bf 41 b9 9 ae 46 a0 a9 66 2d c7 6 f6 d7 66 f1 4 f8 ad 8a 9f 4d 7e e5 9c 45 67 16 15 33 70 f0 1 d5 c0 38 39 f5 fd 5e 15 4f e3 fe ea 70 fa 30 c9 e0 18 ab 64 a9 fe 2c 89 78 a2 96 b6 76 3e 2e a2 ae 2e e0 69 80 8d 51 9 56 80 f4 1a 73 9a 70 f3 e7 c1 49 49 c3 41 3 c6 ce 3e a8 68 71 3f 2 b2 9b 27 8e 63 ce 59 38 64 d1 75 b7 b7 1f 62 eb 4d 1d de c7 21 e0 67 85 b e6 c3 80 0 60 54 47 e ef 3 f9 33 7b 78 e2 3e db e4 8e 76 73 45 3 38 34 1e dd 43 3e 72 a7 37 72 5 34 8e f4 ba 9d 71 6c e 45 49 fa 92 a f6 b bf 5 b 4f dc bd 19 0 7e d2 ef 94 d 3b 78 17 37 d9 ae 19 3a 7e 46 7d ea e4 3a 8c e1 e5 9 50 a2 eb df f2 57 97 bc f2 c3 a7 6f 19 7f 2c 1a 3f 94 25 19 4b b2 37 ed ce 97 f ae f ec c9 f5 be f0 8f 72 1c 34 84 1b 11 25 dd 44 8b 99 75 a4 77 3d e1 1d 26 41 58 55 5f d5 27 82 c d3 2a f8 4 aa 8d 5e e4 79 0 49 43 59 27 5e 15 87 a f4 c4 57 b6 e1 f8 79 3b d3 20 69 5e d0 80 6a 6b 9f 43 79 84 94 d0 77 b6 fc f 3 22 ca b9 35 c0 e8 7b e9 25 26 7f c9 fb e4 a7 fc bb b7 75 ac 7b bc f4 bb 4f a8 80 9b 73 da 3 94 da 87 e7 94 4c 80 b3 f1 2e 5b d8 2 65 25 bb 92 f4 92 e3 de 8 ee 2 30 df 84 a4 69 a6 a1 d0 9c e7 8e f 8 71 4b d0 1c 14 ac 7c c6 e3 2a 2e 2a c2 32 bc 21 c4 2f 4d df 9a f3 10 3e e5 c5 7f ad e4 fb ae 99 bf 58 0 20 0 0 0 0 0 0 0 0 0 0 [2013-11-06 15:11:08,602] main - b.b():? - Enterring getResponse [2013-11-06 15:11:08,618] main - b.a():? - Enterring getTimeoutValue(AceRequest AceAuthV4Request[AbstractAceRequest[ hdr=AcePacketHeader[Type=92 Ver=5 AppID=3 Enc=ENCRYPT Hi-Proto=5 Opt=0 CirID=0] created=1383750668571 trailer=AcePackeTrailer[nonce=39e7a607b517c4dd crc=722833884]] user=bmatthews node-sec-req=0 wpcodes=null resp-mac=0 m-resp-mac=0 client=192.168.10.3 passcode==ZTmY|? sec-sgmt=AceSecondarySegments[ cnt=3] response=none]) [2013-11-06 15:11:08,618] main - b.a():? - acm base timeout: 5 [2013-11-06 15:11:08,618] main - b.b():? - Timeout is 5000 [2013-11-06 15:11:08,618] main - b.b():? - Current retries: 0 [2013-11-06 15:11:10,618] main - b.b():? - Received 508 bytes from 192.168.10.121; contents: 6c 5 0 3 3 6 0 0 0 0 0 1 4d 18 55 ca 18 df 84 49 70 ee 24 4a a5 c3 1c 4e 36 d8 51 ad c7 ef 49 89 6e 2e 23 b4 7e 49 73 4 15 d f4 d5 c0 bf fc 72 5b be d1 62 be e0 de 23 56 bf 26 36 7f b f0 ba 42 61 9b 6f 4b 96 88 9c e9 86 df c6 82 e5 4c 36 ee dc 1e d8 a1 0 71 65 89 dc ca ee 87 ae d6 60 c 86 1c e8 ef 9f d9 b9 4c ed 7 55 77 f3 fc 92 61 f9 32 70 6f 32 67 4d fc 17 4e 7b eb c3 c7 8c 64 3f d0 d0 c7 86 ad 4e 21 41 a2 80 dd 35 ba 31 51 e2 a0 ef df 82 52 d0 a8 43 cb 7c 51 c 85 4 c5 b2 ec 8f db e1 21 90 f5 d7 1b d7 14 ca c0 40 c5 41 4e 92 ee 3 ec 57 7 10 45 f3 54 d7 e4 e6 6e 79 89 9a 21 70 7a 3f 20 ab af 68 34 21 b7 1b 25 e1 ab d 9f cd 25 58 5a 59 b1 b8 98 58 2f 79 aa 8a 69 b9 4c c1 7d 36 28 a3 23 f5 cc 2b ab 9e f a1 79 ab 90 fd 5f 76 9f d9 86 d1 fc 4c 7a 4 24 6d de 64 f1 53 22 b0 b7 91 9a 7c a2 67 2a 35 68 83 74 6a 21 ac eb f8 a2 29 53 21 2f 5a 42 d6 26 b8 f6 7f 79 96 5 3b c2 15 3a b d0 46 42 b7 74 4e 1f 6a ad f5 73 70 46 d3 f8 e a3 83 a3 15 29 6e 68 2 df 56 5c 88 8d 6c 2f ab 11 f1 5 73 58 ec 4 5f 80 e3 ca 56 ce 8 b9 73 7c 79 fc 3 ff f1 40 97 bb e3 fb 35 d1 8d ba 23 fc 2d 27 5b f7 be 15 de 72 30 b e d6 5c 98 e8 44 bd ed a4 3d 87 b8 9b 35 e9 64 80 9a 2a 3c a2 cf 3e 39 cb f6 a2 f4 46 c7 92 99 bc f7 4a de 7e 79 9d 9b d9 34 7f df 27 62 4f 5b ef 3a 4c 8d 2e 66 11 f7 8 c3 84 6e 57 ba 2a 76 59 58 78 41 18 66 76 fd 9d cb a2 14 49 e1 59 4a 6e f5 c3 94 ae 1a ba 51 fc 29 54 ba 6c 95 57 6b 20 87 cc b8 dc 5f 48 72 9c c0 2c dd 60 56 4e 4c 6c 1d 40 bd 4 a1 10 4e a4 b1 87 83 dd 1c f2 df 4c [2013-11-06 15:11:10,618] main - a.a():? - Response status is: 1 [2013-11-06 15:11:10,618] main - a.a():? - Authenticaton failed for bmatthews !

• How can I avoid Windows 8.1 resetting my font size?

  - by Michael Tsang

  I am using Windows 8.1 on my laptop, which has a 15.6" screen with resolution 1366x768. I measured the screen with a ruler and calculated its DPI, which is 101. Therefore, I have set the scaling to 105%. However, when I change to an external monitor, which is a huge one with resolution 1920x1080 and DPI 93, I need to change the scaling to 97% but when I change the DPI back and forth, my font sizes have get resetted. I prefer using font sizes 14 on my title bars, message boxes and icons and font sizes 13 on my palette titles, menus and tooltips. However, as my laptop screen is too small, in order to make my apps fit on screen, I use font sizes 12 on my title bars, message boxes and icons and font sizes 11 on my palette titles, menus and tooltips. I don't know why I can't resize the window to make it larger than my screen in Windows (but it is possible in Kubuntu), therefore, some parts of my apps cannot be shown with my preferred font size. I have tried changing both the DPI and the font size by using .reg files. Before switching to my laptop screen, I apply the following: Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Control Panel\Desktop] "LogPixels"=dword:00000065 [HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics] "CaptionFont"=hex:ef,ff,ff,ff,00,00,00,00,00,00,00,00,00,00,00,00,bc,02,00,00,\ 00,00,00,01,00,00,05,00,53,00,65,00,67,00,6f,00,65,00,20,00,55,00,49,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 "SmCaptionFont"=hex:f0,ff,ff,ff,00,00,00,00,00,00,00,00,00,00,00,00,bc,02,00,\ 00,00,00,00,01,00,00,05,00,53,00,65,00,67,00,6f,00,65,00,20,00,55,00,49,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 "MenuFont"=hex:f0,ff,ff,ff,00,00,00,00,00,00,00,00,00,00,00,00,90,01,00,00,00,\ 00,00,01,00,00,05,00,53,00,65,00,67,00,6f,00,65,00,20,00,55,00,49,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 "StatusFont"=hex:f0,ff,ff,ff,00,00,00,00,00,00,00,00,00,00,00,00,90,01,00,00,\ 00,00,00,01,00,00,05,00,53,00,65,00,67,00,6f,00,65,00,20,00,55,00,49,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 "MessageFont"=hex:ef,ff,ff,ff,00,00,00,00,00,00,00,00,00,00,00,00,90,01,00,00,\ 00,00,00,01,00,00,05,00,53,00,65,00,67,00,6f,00,65,00,20,00,55,00,49,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 "IconFont"=hex:ef,ff,ff,ff,00,00,00,00,00,00,00,00,00,00,00,00,90,01,00,00,00,\ 00,00,01,00,00,05,00,53,00,65,00,67,00,6f,00,65,00,20,00,55,00,49,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 "AppliedDPI"=dword:00000065 Before switching to my external display, I apply this: Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Control Panel\Desktop] "LogPixels"=dword:0000005d [HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics] "CaptionFont"=hex:ed,ff,ff,ff,00,00,00,00,00,00,00,00,00,00,00,00,bc,02,00,00,\ 00,00,00,01,00,00,05,00,53,00,65,00,67,00,6f,00,65,00,20,00,55,00,49,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 "SmCaptionFont"=hex:ee,ff,ff,ff,00,00,00,00,00,00,00,00,00,00,00,00,bc,02,00,\ 00,00,00,00,01,00,00,05,00,53,00,65,00,67,00,6f,00,65,00,20,00,55,00,49,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 "MenuFont"=hex:ef,ff,ff,ff,00,00,00,00,00,00,00,00,00,00,00,00,90,01,00,00,00,\ 00,00,01,00,00,05,00,53,00,65,00,67,00,6f,00,65,00,20,00,55,00,49,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 "StatusFont"=hex:ef,ff,ff,ff,00,00,00,00,00,00,00,00,00,00,00,00,90,01,00,00,\ 00,00,00,01,00,00,05,00,53,00,65,00,67,00,6f,00,65,00,20,00,55,00,49,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 "MessageFont"=hex:ed,ff,ff,ff,00,00,00,00,00,00,00,00,00,00,00,00,90,01,00,00,\ 00,00,00,01,00,00,05,00,53,00,65,00,67,00,6f,00,65,00,20,00,55,00,49,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 "IconFont"=hex:ed,ff,ff,ff,00,00,00,00,00,00,00,00,00,00,00,00,90,01,00,00,00,\ 00,00,01,00,00,05,00,53,00,65,00,67,00,6f,00,65,00,20,00,55,00,49,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,\ 00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 "AppliedDPI"=dword:0000005d I expect after applying the file, the DPI settings and the font sizes take effect at the next sign in. However, on my laptop screen, after I applied the file, signed out and in, the DPI setting changed, but the font sizes were resetted to tiny, and I had to apply the same file, signed out and in again to get the correct font size. The situation is even worse on my external monitor. After I applied the file, signed out and in, both the DPI setting and the font sizes were resetted to their default values, which were 96 DPI (the physical DPI as measured by dividing the resolution by the physical size is 93) and font size 9, which is totally unacceptable. How can I write the .reg files such that the settings can be correctly applied with a single sign in?

• Formmail redirect question

  - by Elliot

  So I'm using a basic formmail script. Within the script I'm using a redirect variable. The value of the redirect is something like,"http://www.mysite.com/NewOLS_GCUK_EN/bling.aspx?BC=GCUK&IBC=CSEE&SIBC=CSEE" When the redirect action happens however, the url appears in the browser as: http://www.mysite.com/NewOLS_GCUK_EN/bling.aspx?BC=GCUK&amp;IBC=CSEE&amp;SIBC=CSEE you can see the &'s are replaced with "& a m p ;" is there any way to fix this? Thanks! -Elliot

• Context-sensitive grammar for specific language

  - by superagio

  How can I construct a grammar that generates this language? Construct a grammar that generates L: L = {a^n b^m c^k|k>n, k>m} I believe my productions should go along this lines: S-> ABCC A-> a|aBC|BC B-> b|bBC C-> c|Cc CB->BC The idea is to start with 2 c and keep always one more c, and then with C-c|Cc ad as much c as i want. How can my production for C remember the numbers of m and n.

• Exception - Illegal Block size during decryption(Android)

  - by Vamsi

  I am writing an application which encrypts and decrypts the user notes based on the user set password. i used the following algorithms for encryption/decryption 1. PBEWithSHA256And256BitAES-CBC-BC 2. PBEWithMD5And128BitAES-CBC-OpenSSL e_Cipher = Cipher.getInstance(PBEWithSHA256And256BitAES-CBC-BC); d_Cipher = Cipher.getInstance(PBEWithSHA256And256BitAES-CBC-BC); e_Cipher.init() d_Cipher.init() encryption is working well, but when trying to decrypt it gives Exception - Illegal Block size after encryption i am converting the cipherText to HEX and storing it in a sqlite database. i am retrieving correct values from the sqlite database during decyption but when calling d_Cipher.dofinal() it throws the Exception. I thought i missed to specify the padding and tried to check what are the other available cipher algorithms but i was unable to found. so request you to please give the some knowledge on what are the cipher algorithms and padding that are supported by Android? if the algorithm which i used can be used for padding, how should i specify the padding mechanism? I am pretty new to Encryption so tried a couple of algorithms which are available in BouncyCastle.java but unsuccessful. As requested here is the code public class CryptoHelper { private static final String TAG = "CryptoHelper"; //private static final String PBEWithSHA256And256BitAES = "PBEWithSHA256And256BitAES-CBC-BC"; //private static final String PBEWithSHA256And256BitAES = "PBEWithMD5And128BitAES-CBC-OpenSSL"; private static final String PBEWithSHA256And256BitAES = "PBEWithMD5And128BitAES-CBC-OpenSSLPBEWITHSHA1AND3-KEYTRIPLEDES-CB"; private static final String randomAlgorithm = "SHA1PRNG"; public static final int SALT_LENGTH = 8; public static final int SALT_GEN_ITER_COUNT = 20; private final static String HEX = "0123456789ABCDEF"; private Cipher e_Cipher; private Cipher d_Cipher; private SecretKey secretKey; private byte salt[]; public CryptoHelper(String password) throws InvalidKeyException, NoSuchAlgorithmException, NoSuchPaddingException, InvalidAlgorithmParameterException, InvalidKeySpecException { char[] cPassword = password.toCharArray(); PBEKeySpec pbeKeySpec = new PBEKeySpec(cPassword); PBEParameterSpec pbeParamSpec = new PBEParameterSpec(salt, SALT_GEN_ITER_COUNT); SecretKeyFactory keyFac = SecretKeyFactory.getInstance(PBEWithSHA256And256BitAES); secretKey = keyFac.generateSecret(pbeKeySpec); SecureRandom saltGen = SecureRandom.getInstance(randomAlgorithm); this.salt = new byte[SALT_LENGTH]; saltGen.nextBytes(this.salt); e_Cipher = Cipher.getInstance(PBEWithSHA256And256BitAES); d_Cipher = Cipher.getInstance(PBEWithSHA256And256BitAES); e_Cipher.init(Cipher.ENCRYPT_MODE, secretKey, pbeParamSpec); d_Cipher.init(Cipher.DECRYPT_MODE, secretKey, pbeParamSpec); } public String encrypt(String cleartext) throws IllegalBlockSizeException, BadPaddingException { byte[] encrypted = e_Cipher.doFinal(cleartext.getBytes()); return convertByteArrayToHex(encrypted); } public String decrypt(String cipherString) throws IllegalBlockSizeException { byte[] plainText = decrypt(convertStringtobyte(cipherString)); return(new String(plainText)); } public byte[] decrypt(byte[] ciphertext) throws IllegalBlockSizeException { byte[] retVal = {(byte)0x00}; try { retVal = d_Cipher.doFinal(ciphertext); } catch (BadPaddingException e) { Log.e(TAG, e.toString()); } return retVal; } public String convertByteArrayToHex(byte[] buf) { if (buf == null) return ""; StringBuffer result = new StringBuffer(2*buf.length); for (int i = 0; i < buf.length; i++) { appendHex(result, buf[i]); } return result.toString(); } private static void appendHex(StringBuffer sb, byte b) { sb.append(HEX.charAt((b>>4)&0x0f)).append(HEX.charAt(b&0x0f)); } private static byte[] convertStringtobyte(String hexString) { int len = hexString.length()/2; byte[] result = new byte[len]; for (int i = 0; i < len; i++) { result[i] = Integer.valueOf(hexString.substring(2*i, 2*i+2), 16).byteValue(); } return result; } public byte[] getSalt() { return salt; } public SecretKey getSecretKey() { return secretKey; } public static SecretKey createSecretKey(char[] password) throws NoSuchAlgorithmException, InvalidKeySpecException { PBEKeySpec pbeKeySpec = new PBEKeySpec(password); SecretKeyFactory keyFac = SecretKeyFactory.getInstance(PBEWithSHA256And256BitAES); return keyFac.generateSecret(pbeKeySpec); } } I will call mCryptoHelper.decrypt(String str) then this results in Illegal block size exception My Env: Android 1.6 on Eclipse

• car and cdr in scheme is driving me crazy ...

  - by kristian Roger

  Hi Im facing a probem with the car and cdr functions for example: first I defined a list caled it x (define x (a (bc) d ( (ef) g ) )) so x now is equal to (a (bc) d ( (ef) g ) now for example I need to get the g from this list using only car and cdr (!! noshortcuts as caddr cddr !!) the correct answer is: (car(cdr(car(cdr(cdr(cdr x)))))) BUT how ? :-( I work according to the rule (the car gives the head of list and cdr gives the tail) and instead of getting the answer above I keep reaching wronge answers can any one help me in understanding this ... give me step or a way to solve it step by step thanx in advance Im really sick of scheme language.

• Git: removing selected commits from repository

  - by xk0der

  I would like to remove selected commits from a linear commit tree, so that the commits do not show in the commit log. My commit tree looks something like: R--A--B--C--D--E--HEAD I would like to remove the B and C commits. So that they do not show in the commit log, but changes from A to D should be preserved. Maybe by introducing a single commit, so that B and C become BC and the tree looks like. R--A--BC--D--E--HEAD Or, ideally, after A comes D directly. D' representing changes from A to B, B to C and C to D. R--A--D'--E--HEAD Is this possible? if yes, how? Some notes that might be helpful: This is a fairly new project so has no branches as of now, hence no merges as well. Side note: It's a personal project, so no, I'm not trying to destroy any evidence :)

• Write PEM encoded certificate in file - java

  - by user1349407

  Good day. I recently create X.509 certificate by using bouncy castle API. I need to save the certificate result rather than display the result. I tried to use FileOutputStream, but it does not work. regards the result is like follows -----BEGIN CERTIFICATE----- MIICeTCCAeKgAwIBAgIGATs8OWsXMA0GCSqGSIb3DQEBCwUAMBsxGTAXBgNVBAMT... -----END CERTIFICATE----- The code is belows import java.io.FileOutputStream; //example of a basic CA public class PKCS10CertCreateExample { public static X509Certificate[] buildChain() throws Exception { //create the certification request KeyPair pair = chapter7.Utils.generateRSAKeyPair(); PKCS10CertificationRequest request = PKCS10ExtensionExample.generateRequest(pair); //create a root certificate KeyPair rootPair=chapter7.Utils.generateRSAKeyPair(); X509Certificate rootCert = X509V1CreateExample.generateV1Certificate (rootPair); //validate the certification request if(!request.verify("BC")) { System.out.println("request failed to verify!"); System.exit(1); } //create the certificate using the information in the request X509V3CertificateGenerator certGen = new X509V3CertificateGenerator(); certGen.setSerialNumber(BigInteger.valueOf(System.currentTimeMillis())); certGen.setIssuerDN(rootCert.getSubjectX500Principal()); certGen.setNotBefore(new Date(System.currentTimeMillis())); certGen.setNotAfter(new Date(System.currentTimeMillis()+50000)); certGen.setSubjectDN(request.getCertificationRequestInfo().getSubject()); certGen.setPublicKey(request.getPublicKey("BC")); certGen.setSignatureAlgorithm("SHA256WithRSAEncryption"); certGen.addExtension(X509Extensions.AuthorityKeyIdentifier, false, new AuthorityKeyIdentifierStructure(rootCert)); certGen.addExtension(X509Extensions.SubjectKeyIdentifier, false, new SubjectKeyIdentifierStructure(request.getPublicKey("BC"))); certGen.addExtension(X509Extensions.BasicConstraints, true, new BasicConstraints(false)); //certGen.addExtension(X509Extensions.KeyUsage, true, new BasicConstraints(false)); certGen.addExtension(X509Extensions.KeyUsage, true, new KeyUsage(KeyUsage.digitalSignature | KeyUsage.keyEncipherment)); certGen.addExtension(X509Extensions.ExtendedKeyUsage, true, new ExtendedKeyUsage(KeyPurposeId.id_kp_serverAuth)); //extract the extension request attribute ASN1Set attributes = request.getCertificationRequestInfo().getAttributes(); for(int i=0;i!=attributes.size();i++) { Attribute attr = Attribute.getInstance(attributes.getObjectAt(i)); //process extension request if(attr.getAttrType().equals(PKCSObjectIdentifiers.pkcs_9_at_extensionRequest)) { X509Extensions extensions = X509Extensions.getInstance(attr.getAttrValues().getObjectAt(0)); Enumeration<?> e = extensions.oids(); while(e.hasMoreElements()) { DERObjectIdentifier oid = (DERObjectIdentifier)e.nextElement(); X509Extension ext = extensions.getExtension(oid); certGen.addExtension(oid, ext.isCritical(), ext.getValue().getOctets()); } } } X509Certificate issuedCert = certGen.generateX509Certificate(rootPair.getPrivate()); return new X509Certificate[]{issuedCert, rootCert}; } public static void main(String[] args) throws Exception { X509Certificate[] chain = buildChain(); PEMWriter pemWrt = new PEMWriter(new OutputStreamWriter(System.out)); pemWrt.writeObject(chain[0]); //pemWrt.writeObject(chain[1]); pemWrt.close(); //write it out //FileOutputStream fOut = new FileOutputStream("pkcs10req.req"); //fOut.write(chain[0].toString()); //fOut.write() //System.out.println(chain[0].toString()); //fOut.close(); } }
