  - by superartsy

  I have a Weblogic server installed and a site. The SSL port is 7002 When I try to access a secure page ex https://localhost:7002/site in Internet Explorer I get a certificate error. Clicking the continue to website does not do anything. In chrome, I get the opton to "Ignore Anyway" and I can continue to see the page. But in Internet explorer I having no such luck. Not sure what I am doing wrong. I am using the default certificates that come wih weblogic installation. I have not generated any private keys or certificates. Any help appreciated.

• Accepting bank account information in a form

  - by jeffthink

  What security concerns are there when accepting a user's bank account information (account number and routing number) via a form on a page that is using SSL, and posting it back to the server where I then curl off a HTTPS request to send that information to an ACH service like First ACH or ACH Direct via their API? We wouldn't be saving the bank account information in our database. I know another option is to use Paypal's Mass Pay API, but they think it's unprofessional (at least for their business) to require customers to have a paypal account to get paid. Thoughts?

• Client / Server security from mobile to website

  - by Amir Latif

  Hey. Am new to the world of web programming and learning a bunch of fairly simple new pieces of tech, trying to piece them all together. So, we have a simple client (currently iPhone, to move to J2ME soon) that's pulling down lists of data via PHP, which is talking to a MySQL db. I have a rudimentary user/login system so that data is only served to someone who matches a known user etc, either on the website or on the client. All the php scripts on the website that query the DB check to make sure an active session is in place, otherwise dumping the user back to the login screen. I've read a little about SSL and want to know if that is sufficient to protect the website AND the data passing between the server and the client?

• Keystore in PKCS12 format seems empty to keytool, but is read by Firefox?!

  - by hjh

  I have a problem with a keystore in pkcs12 format, which contains a private key I need to use to authenticate myself (using mutual authentication) to a remote SSL server. The keystore file can be read perfectly fine by Firefox, and when used, I can access the remote server without problems. However, my Java program does not work with the keystore file. And if I use keytool to list keys inside the file, it seems empty -- while it is clearly not! How can I get Java/keytool to see the private key inside the keystore?

• Database Design Question: GUID + Natural Numbers

  - by Alan

  For a database I'm building, I've decided to use natural numbers as the primary key. I'm aware of the advantages that GUID's allow, but looking at the data, the bulk of row's data were GUID keys. I want to generate XML records from the database data, and one problem with natural numbers is that I don't want to expose my database key's to the outside world, and allow users to guess "keys." I believe GUID's solve this problem. So, I think the solution is to generate a sparse, unique iD derived from the natural ID (hopefully it would be 2-way), or just add an extra column in the database and store a guid (or some other multibyte id) The derived value is nicer because there is no storage penalty, but it would be easier to reverse and guess compared to a GUID. I'm (buy) curious as to what others on SO have done, and what insights they have.

• Cannot connect via HTTPS in Java app on MacOSX (Certificate validation issue)

  - by johnnyx

  I have a java application that connects to a webservice over https. The domain where i host the webservice has a valid Goddaddy issued SSL certificate. The application works fine on Windows but on MacOSx i receive the following exception when attempting to connect to the webservice via https. sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target I've tested it on two machines running Mac OS X 10.7.2 with the latest java runtime updates. I understand this is usually a problem with self signed certificates that need to be added manually, but i have a valid Godaddy issued certificate. In webbrowsers (safari & firefox) on mac os the certificate is recognized and seems ok. I even tried adding the certificate to the key chain manually like in the gase of a self signed one but to no result.

• JRuby on Rails deployment

  - by Vagmi Mudumbai

  I need to host a JRuby on Rails app on Mongrel. The problem is that I need to support mutual authentication. I know that I could just host it behind a Apache with mod_proxy use mod_ssl to pass the cred or part of the cred as a request header to rails. But I want the whole stack to be Java. Is there a Java application server that can do mod_proxy + ssl kind of configuration without me having to install Apache. Also, we need this to be platform independent. IIS or Apache+OpenSSL is actually not a preferred alternative. Any alternative deployment configurations are also welcome.

• Securing a REST API

  - by Christopher McCann

  I am in the middle of developing a REST API - the first one I ever have. The data being passed through the API is not of such a critical nature that there will be loss of life, economics etc if it was intercepted but at the same time I would like it to be secure. The data being transferred is simply like the data that would be transferred on Twitter or Facebook - not overly confidential but still should be kept private. What is the best way to secure this data? Am I best to use HTTP Basic Auth over SSL or should I be looking into something like OAuth. I have never really used REST much before so bit of a first for me. Thanks

• Question about SSL Certificate.

  - by smwikipedia

  Hi experts, I am trying to make a SSL connection to a web site. Each time I enter the https:// address and press enter, the IE8 prompts me to select the Certificate (Client Certificate) to send to the server. I got 2 certificates to choose from. And they are stored in the IE8 - Internet Options - Content - Certificates - Personal. Since my server and client are the same machine, I want to use a single certificate for both server and client. And this certificate is a IIS generated self signed certificate. I do the following steps: 1- Generate a self-signed-cert in IIS; 2- Bind my site to https and choose the above self-signed-cert 3- Import the self-signed-cert at the IE8 - Internet Options - Content - Certificates - Personal. Then I use the https link to access my page, it is still prompts me to choose a certificate. But I cannot see my newly imported self-signed-cert. Why?

• Maximum open sll connections on Windows

  - by scooterman

  version: erlang R13B Hi all, how can I increase the amount of ssl ports/handles that my network server is able to create on Windows? On linux I was able to successful create about 1000 connections using: -env ERL_MAX_PORTS 80000 -P 268435456 and changing the maximum open fd's using ulimit. On windows apparently there is no effect using the same configuration, and sadly the number of open connections are VERY small (about 30, and it opens 6 handles for each one). I've noticed that the shell starts two other children processes, inet_gethost.exe and ssl_esock.exe. If these are the ones that I have to increase the port count, how do I do that? Thanks,

• Windows Phone 7, download xml over ssl with authentication

  - by Snake

  Hi, I'm trying to download a file from my provider. The url is protected with basic username and password, and everything is sent over ssl. So I try to do this: WebClient proxy = new WebClient(); proxy.DownloadStringCompleted += (o, dscea) => System.Diagnostics.Debugger.Break(); proxy.Credentials = new NetworkCredential("username", "password"); proxy.DownloadStringAsync(new Uri("https://..../.../data.xml")); As you can see I try to validate. The data IS correct, and the code works when I try to download something from twitter. What am I forgetting to connect to this xml file?

• Windows Phone 7 Application + WCF + SSL + Username Authentication

  - by s7orm

  Hello, I have developed a test service with WCF, which I try to consume from a Windows Phone 7 Application, however when calling a method from the service I get a weird exception: There was no endpoint listening at https://server/Service.svc that could accept the message. This is often caused by an incorrect address or SOAP action. The WCF service uses a custom binding with UserNameOverTransport authentication and SSL. For the authorization I am using an implementation of the UserNamePasswordValidator. If I try to consume the service from a console or silverlight application (cross domain policy is enabled) - it works fine (authorization as well). And the most weird thing is that the ServiceReferences.ClientConfig file generated for the WP7 App is exactly the same as the config file generated for the silverlight application. I have no idea what is wrong with my service...

• Testing HTTPS files with MAMP

  - by jgreenawalt

  I am running MAMP locally on my laptop, and I like to test as much as I can locally. Unfortunately, since I work on e-commerce stuff (PHP), I normally force ssl in most of the checkout forms and it just fails on my laptop. Is there any easy configuration that I might be missing to allow "https" to run under MAMP? Please note, I know that I could configure Apache by hand, re-compile PHP, etc. but I'm just wondering if there's an easier way for a lazy programmer. Thanks

• Django: HTTPS for just login page?

  - by Mark

  I just added this SSL middleware to my site http://www.djangosnippets.org/snippets/85/ which I used to secure only my login page so that passwords aren't sent in clear-text. Of course, when the user navigates away from that page he's suddenly logged out. I understand why this happens, but is there a way to pass the cookie over to HTTP so that users can stay logged in? If not, is there an easy way I can use HTTPS for the login page (and maybe the registration page), and then have it stay on HTTPS if the user is logged in, but switch back to HTTP if the user doesn't log in? There are a lot of pages that are visible to both logged in users and not, so I can't just designate certain pages as HTTP or HTTPS.

• (Secure) alternative to TLS / SSLv3 ?

  - by CSkau

  Toying with an idea for a F2F networked application I've just been reading up on secure communication. I quickly settled with the idea of using TLS / SSL as the basis for any communication since it employs Public Key encryption at the protocol level and thus is perfect for my needs. However I was surprised to read (on wikipedia) that the newest version of TLS, SSLv3 uses a mix of MD5 and SHA-1 "because if any vulnerability was found in one of these algorithms the other would prevent it from compromising SSLv3". However, as I take it, lately both have been found flawed ! So my questions are thus: Does this not mean that SSLv3 is basically flawed, or am I not reading close enough ? And if so does a "secure" alternative to SSLv3 exist ?

• Export Certificate Windows Server 2008

  - by user1432032

  I need to export the private key of a self-created SSL-certificate on a Windows Server 2008. However at Microsoft Management Console (the certificate is located, if it matter, in Personal-Certificate folder) the option "Yes, export the private key" is greyed out. Reading the provided help section it tells that the certificate needed to "be made exportable" during creation. However it also says that it is ONLY a limitation if it was created using Windows Server 2003. It doesn´t say anything how to fix it though on a Windows 2008 Server. The certificate is self-signed. I want to export to PKCS12 format. I´m accessing MMC as administrator so there should not be any permission issues. How can I make this certificate "exportable"?

• Reset array keys in multidimensional array

  - by nbaumann

  I've been looking around for a solution to this with no real success. I have a multidimensional array of parents and children with no limits on depth. This is generated from a database but the issue is that the item ID becomes the key using my way of arranging a flat array into a multidimensional array like so: Array( [28] => Array ( [id] => 28 [color] => #ff24e5 [name] => Personal [parent_id] => [children] => Array ( [23] => Array ( [id] => 23 [color] => #41c3a3 [name] => Shopping [parent_id] => 28 [children] => Array ( [22] => Array ( [id] => 22 [color] => #8be32b [name] => Deals [parent_id] => 23 [children] => Array ( ) ) ) ) [150] => Array ( [id] => 150 [color] => #e9a3f0 [name] => Orders [parent_id] => 28 [children] => Array ( ) ) ) ) ) What I would like, is a function that does the following: Array ( [0] => Array ( [id] => 28 [color] => #ff24e5 [name] => Personal [parent_id] => [children] => Array ( [0] => Array ( [id] => 23 [color] => #41c3a3 [name] => Shopping [parent_id] => 28 [children] => Array ( [0] => Array ( [id] => 22 [color] => #8be32b [name] => Deals [user_id] => 1 [selected] => 0 [parent_id] => 23 [children] => Array ( ) ) ) ) [1] => Array ( [id] => 150 [color] => #e9a3f0 [name] => Orders [parent_id] => 28 [children] => Array ( ) ) ) ) ) Essentially reassign keys starting from 0. I've tried numerous methods, but I'm assuming that I need to find a recursive solution and when I tried that, it destroyed my array. I was reading up on the array_walk_recursive() function, but I don't quite know what to do beyond that. Essentially, is there a way to reset numeric keys in a multidimensional array? Thanks for the help!

• ASP.NET MVC Class level custom data-annotation and ModelState keys

  - by Neil

  Hi, I have custom class level validation attribute, inheriting from ValidationAttribute, on my model. How come it doesn't register a key in the ModelState when its IsValid is false? I can see the the error message in the ModelState.Values collection, but the ModelState.Keys collection only shows an empty string "". Can I provide a key for it - presumably this is because its not assigned to a property? I wanna be able to use ModelState.Remove in my controller to remove this error upon a certain condition, but I have no Key! Any ideas?

• Ruby Irb reacts strangely to control keys

  - by eegg

  Hi. I'm (extremely) new to Ruby, having started today. I just moved from my system's Ruby 1.8 installation to Ruby 1.9, compiled from source. In doing so, irb has taken a turn for the worse. It reacts in a most unfriendly way to the non-alphanumeric control keys: UP key prints: ^[[A DOWN key prints: ^[[B DELETE key prints: ^[[3~ ...and so on. The main result of this for me is that I have no access to previously issued commands. Nor does tab-completion work; though none of this seems to be an issue with Wirble - the same happens when I remove my ~/.irbrc. I'm using: Ubuntu 9.10 GNOME Terminal 2.28.1 ruby 1.9.1p376 (2009-12-07 revision 26041) [i686-linux] Irb version 0.9.5 (05/04/13) Any ideas? :(

• How to digitally sign a message with M2Crypto using the keys within a DER format certificate

  - by Pablo Santos

  Hi everyone. I am working on a project to implement digital signatures of outgoing messages and decided to use M2Crypto for that. I have a certificate (in DER format) from which I extract the keys to sign the message. For some reason I keep getting an ugly segmentation fault error when I call the "sign_update" method. Given the previous examples I have read here, I am clearly missing something. Here is the example I am working on: from M2Crypto.X509 import * cert = load_cert( 'certificate.cer', format=0 ) Pub_key = cert.get_pubkey() Pub_key.reset_context(md='sha1') Pub_key.sign_init() Pub_key.sign_update( "This should be good." ) print Pub_key.sign_final() Thanks in advance for the help, Pablo

• Piano Keys using GridLayout (or Something Else)

  - by yar

  I am creating a container of JComponents which will look like a piano keyboard. The black keys look like this (Groovy) def setBlackNotes(buttons) { def octaves = (int)(buttons.size() / 5) def gridLayout = new GridLayout(1, octaves*7); def blackNotePanel = new JPanel(gridLayout) this.add blackNotePanel def i = 0 octaves.times { 2.times { blackNotePanel.add buttons[i++] } blackNotePanel.add Box.createHorizontalBox() 3.times { blackNotePanel.add buttons[i++] } blackNotePanel.add Box.createHorizontalBox() } } Which is just what I need, and looks like this: but then I'd like to move this over to the right by half-a-key width. All of my attempts to move the blackNotePanel over by an arbitrary width -- wrapping it a BorderLayout, a MigLayout, etc. -- have failed or changed the spacing of the GridLayout radically. Any suggestions on how to move this over to the right by an arbitrary amount in pixels?

• How to build C# object from a FormCollection with complex keys

  i have a javascript object, obj, that gets passed to an mvc action via a $.post() like so: var obj = { Items: [{ Text: "", Value: { Property1: "", Property2: "" }, { Text: "", Value: { Property1: "", Property2: "" }] }; $.post('MyAction', obj, function() {}); the action signature looks like this: public ActionResult MyAction(FormCollection collection) { } i need to be able to build an object from the FormCollection, however i'm running into an issue where the keys are in the form: "Items[0][Text]" "Items[0][Value][Property1]" "Items[0][Value][Property2]" "Items[1][Text]" "Items[1][Value][Property1]" "Items[1][Value][Property2]" i'm wondering if there's a clean way to build the desired C# object from the given FormCollection. i understand that i could change the action method signature to take in the type of object i'm interested in, but that was presenting its own issues.
