  • Generate reasonable length license key with asymmetric encryption?

    - by starkos
    I've been looking at this all day. I probably should have walked away from it hours ago; I might be missing something obvious at this point. Short version: Is there a way to generate and boil down an asymmetrically encrypted hash to a reasonable number of unambiguous, human readable characters? Long version: I want to generate license keys for my software. I would like these keys to be of a reasonable length (25-36 characters) and easily read and entered by a human (so avoid ambiguous characters like the number 0 and the capital letter O). Finally--and this seems to be the kicker--I'd really like to use asymmetric encryption to make it more difficult to generate new keys. I've got the general approach: concatenate my information (user name, product version, a salt) into a string and generate a SHA1() hash from that, then encrypt the hash with my private key. On the client, build the SHA1() hash from the same information, then decrypt the license with the public key and see if I've got a match. Since this is a Mac app, I looked at AquaticPrime, but that generates a relatively large license file rather than a string. I can work with that if I must, but as a user I really like the convenience of a license key that I can read and print. I also looked at CocoaFob which does generate a key, but it is so long that I'd want to deliver it as a file anyway. I fooled around with OpenSSL for a while but couldn't come up with anything of a reasonable length. So...am I missing something obvious here? Is there a way to generate and boil down an asymmetrically encrypted hash to a reasonable number of unambiguous, human readable characters? I'm open to buying a solution. But I work on a number of different of platforms, so I'd want something portable. Everything I've looked at so far has been platform specific. Many, many thanks for a solution! PS - Yes, I know it will still be cracked. I'm trying to come up with something reasonable that, as a user, I would still find friendly.

  • What is the email subject length limit?

    - by Scott Ferguson
    How many characters are allowed to be in the subject line of Internet email? I had a scan of The RFC for email but could not see specifically how long it was allowed to be. I have a colleague that wants to programmatically validate for it. If there is no formal limit, what is a good length in practice to suggest? Cheers,

  • Read variable-length records from a buffer - weird memory issues

    - by bsg
    Hi, I'm trying to implement an i/o intensive quicksort (C++ qsort) on a very large dataset. In the interests of speed, I'd like to read in a chunk of data at a time into a buffer and then use qsort to sort it inside the buffer. (I am currently working with text files but would like to move to binary soon.) However, my data is composed of variable-length records, and qsort needs to be told the length of the record in order to sort. Is there any way to standardize this? The only thing I could think of was rather convoluted: my program currently reads from the buffer until it hits a linefeed character ('10' in ascii), transferring each character over to another array. When it finds a linefeed (the delimiter in the input file), it fills the number of spaces remaining in the buffer for that record (record size is set to 30) with null characters. This way, I should end up with a buffer full of fixed-size records to give qsort. I know there are several problems with my approach, one being that it's just clumsy, another that the record size might conceivably be larger than 30, but is generally much less. Is there a better way of doing this? As well, my current code doesn't even work. When I debug it, it seems to be transferring characters from one buffer to the other, but when I try to print out the buffer, it contains only the first record. Here is my code: FILE *fp; unsigned char *buff; unsigned char *realbuff; FILE *inputFiles[NUM_INPUT_FILES]; buff = (unsigned char *) malloc(2048); realbuff = (unsigned char *) malloc(NUM_RECORDS * RECORD_SIZE); fp = fopen("postings0.txt", "r"); if(fp) { fread(buff, 1, 2048, fp); /*for(int i=0; i <30; i++) cout << buff[i] <<endl;*/ int y=0; int recordcounter = 0; //cout << buff; for(int i=0;i <100; i++) { if(buff[i] != char(10)) { realbuff[y] = buff[i]; y++; recordcounter++; } else { if(recordcounter < RECORD_SIZE) for(int j=recordcounter; j < RECORD_SIZE;j++) { realbuff[y] = char(0); y++; } recordcounter = 0; } } cout << realbuff <<endl; cout << buff; } else cout << "sorry"; Thank you very much, bsg

  • Whats the maximum key length in NSDictionary?

    - by x3ro
    Hey there, I'm currently working on an app which displays a bunch of files in a table, and you can add and remove them and whatsoever. To prevent duplicates in the table, I'd like to create a NSDictionary using the files full path as keys for another NSDictionary which contains all the file information, but I am a little concerned about the maximum key length of NSDictionary, and also whether this solution would be performance killer or not... Looking forward to your answers. Best regards, x3ro

  • Limit URL Parameter Length in Web.Config

    - by Alex
    Is it possible to add some kind of restriction to the web.config to limit URL parameter length? I want to prevent people at the earliest possible point from submitting too large URL parameters so the server doesn't get taxed more than necessary in the event that somebody tries to "attack" it with large invalid URL parameters.

  • What are pros and cons to add line-height to body { }?

    - by metal-gear-solid
    Is it good to add line-height in body{line-height:1.5} or it would be better if i add separately for tag by tag like p{ line height:1em} etc. Edit: body {line-height:in em} create problem with if we put image with float inside Edit: 24 April 2010: If i have to add different line heights to elements like p {line-height: 1.4} h1 {line-height:1.6} h2 {line-height:1.2} ul li {line-height:1.1} then shouldn't i use line height in body {line-height:1.4} if body {line-height:1.4} and h1 {line-height:1.6} then what would be line height for h1?

  • SQL column length query

    - by Mike
    i've been using the following query: select LEN(columnname) as columnmame from dbo.amu_datastaging This works, but is there a way to only return the greatest value instead of all the values? So if i return 1million records and the longest length is 400, the query would just return the value of 400?

    - by stdio
    I've a NULL gtklabel. Upon the occurrence of an event, I set a text in this label (with gtk_label_set_text). How can I reset the gtklabel after the event (reset to NULL)? How can I set the max length (characters) of a GtkTextView? What's the easiest way to set the distance from the margin of a widget in a GtkTable?

  • Length of current selection in Eclipse

    - by Grzegorz Oledzki
    Do you know any easy way to know what is the length of current selection in Eclipse? I.e. I select a line fragment and would like to know how many characters are there? Usually I count them manually, but that's stupid. When being desperate I move to the start, check the column number, move to the end, check the column number, subtract, think a minute if I should add 1 or not... and my selection is lost.

I ran tcpdump to capture packets and I observed some packets have "length as 2962"....how come this is possible with mtu as only 1500? Please clarify. Thanks! Note: flags field is set as DF. and proto is TCP

  • How to find points that intersect an envelope of a line, but not the line itself?

    - by Jacques Bosch
    I have 2 layers. A lines layer and a points layer. For any given line, how can I find the points that intersect the envelope of the line, but not the line itself, or more specifically, not the to point or from point of the line. I can obviously find all the points that intersect the line's envelope, and then do 1 by 1 tests on the found points to see if they intersect the to or from points of the line, but I was hoping there is an easier, faster way to do something of this nature.

  • Nginx: check content-length before file upload takes place

    - by robw
    I'm trying to prevent users from uploading (accidentally or maliciously) very large files to my website. I have nginx max_client_body_size set to 4M, but if a file larger than this is uploaded, then it uploads the entire file before returning 413 (entity too large). I want to make nginx check the Content-Length header, so that it rejects the request before it's uploaded. Alternatively, a Rails solution would also be acceptable. Any help appreciated.
