AES - Encrypt message in Java / Decrypt in asp.net

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :ASP.Net

im currently developing a project which requires to encrypt message in java platform and decrypt in asp.net. In java, i was asked to use the code below to encrypt the message. But i found out i could not decrypt it as i do not know how to get the key, IV fom java. By the way, im using AES decryption method from http://www.obviex.com/samples/Encryption.aspx.

   import java.security.*;
   import javax.crypto.*;
   import javax.crypto.spec.*;
   import java.io.*;

   * This program generates a AES key, retrieves its raw bytes, and
   * then reinstantiates a AES key from the key bytes.
   * The reinstantiated key is used to initialize a AES cipher for
   * encryption and decryption.

   public class AES {

     * Turns array of bytes into string
     * @param buf	Array of bytes to convert to hex string
     * @return	Generated hex string
     public static String asHex (byte buf[]) {
      StringBuffer strbuf = new StringBuffer(buf.length * 2);
      int i;

      for (i = 0; i < buf.length; i++) {
       if (((int) buf[i] & 0xff) < 0x10)

       strbuf.append(Long.toString((int) buf[i] & 0xff, 16));

      return strbuf.toString();

     public static void main(String[] args) throws Exception

Is it possible to write the same encrypt and decrypt method that in MembershipProvider


Hi, I am very confused about encrypting and decrypting password.

What I did is that, I am using a class that extends SqlMembershipProvider, and when I need to encrypt a password, just called base.EncryptPassword() method to do so.

But still, I did not get to know how things are done here, and I really would like to know its codes.

Can anyone provide the code for me please?

WCF - Java web service interop - Signed outgoing message not accepted

Hi, I try to sign a message using a certificate and a private key to call a java (JBoss) web service, but the server refuses to accept my signed message. It only echoes back the same message that I've sent. I have successfully signed the outgoing message using the certificate, and the structure of the message look alright when I compare it to an exampel message supplied by the web service creator. I use a custom binding declared as shown below <binding name="FSACustomServiceBinding"                  closeTimeout="00:01:00"                  openTimeout="00:01:00"                  receiveTimeout="00:10:00"                  sendTimeout="00:01:00">           <textMessageEncoding             messageVersion="Soap11" />           <security             authenticationMode="MutualCertificate"             requireDerivedKeys="false"             keyEntropyMode="ClientEntropy"        &nb

Encrypt in PHP, decrypt in ASP.NET - Encryption doesn't match


Hello all,

I have a problem decrypting a string in ASP.NET wich was encrypted at PHP. As a testcase, i tried to encrypt 'test' in ASP.NET and in PHP, using 3DES in cbc mode. But the encrypted values don't match :(. I want the values to match, so i know for sure i use the same encryption method. Please help me on this, I just don't understand how there are different values...

Here's the code i use in php: 

$cc = "test";

$key = pack("c*", 0x13, 0x56, 0x23, 0x15, 0x81, 0x28, 0x56, 0x51, 0x13, 0x56, 0x23, 0x15, 0x81, 0x28, 0x56, 0x52, 0x13, 0x56, 0x23, 0x15, 0x81, 0x28, 0x56, 0x51);
$iv = pack("c*", 0x42, 0x32, 0x84, 0x25, 0x79, 0x43, 0x11, 0x37);

      $block = mcrypt_get_block_size('tripledes', 'cbc');
      $len = strlen($cc);
      $padding = $block - ($len % $block);
      $cc .= str_repeat(chr($padding),$padding);

$cipher = mcrypt_module_open(MCRYPT_3DES,'','cbc','');
mcrypt_generic_init($cipher, $key, $iv);
$encrypted = mcrypt_generic($cipher,$cc);
echo base64_en

WCF client fails with The message received was unexpected or badly formatted and Decrypt failed with


I have written a console mode WCF client that contacts an Apache based web service that uses OpenSSL  0.9.8 tls or ssl3.
The WCF client uses client certificates on Windows 2008 SP2 x64. The client had been running for months with no problem, and then I started getting the errors below around Nov 8 2010 (below).
I have done my best to include all the details. Please read carefully.
The relevant traces, exceptions, code and config are included in this post.

1.) Fix it.
2.) Find out what 0X80090326 means.
3.) Find out what policies/acl's apply to the situation

The only thing I can be sure of that did not change is the code.

Can anyone point me toward the next step?

- The program executes as a local user (non-domain) that is in the Local Administrators group.
- I can display the server url using IE and Firefox, provided I have the certs installed for personal use.
- The certificates are installed in the LocalMachine store in "TrustedPeople" - NOT the user's location, the machine location. The local user finds the proper key, as the trace below will show.

What I have googled for:
- 0X80090326
- Decrypt failed with error 0X800

Inserting personal error message in ValidationSummary



I am creating a web form that requires a lot of validation. I use many of the validation control in asp.net already like RequiredFieldValidator and CompareValidator. 

My Problem: after my custom validation for the value entered return an error message, and I pressed enter key when the field is empty, my custom error message is overlapped by my ValidationSummary. 

Setting my custom error to visible = false on button click also does not seem to work as it requires for me to enter the value first.

This made me think, is there a way to insert my custom validation inside the ValidationSummary as an error message like for other validation control?

Thanks in advance

UpdatePanel is not a known element - message when upgrading to 1.0 ajax


It worked on one of my old pages.  I change the web.config, renamed all the <asp.

On some aspx page it doesn't recognize the updatepanel.  It only does on one page.  If I create a new aspx page with a different name - then it works.

Should I just create a new web project ajax - then copy all my code into there?  Or is there a way to get those old pages to recognize the new ajax controls?

Very Basic Question - Error message running first page


Hi Everyone,

I am running Windows 7 and I have gone into Control Panel and activated all of the IIS Functions.

The web application I am running was downloaded from the net (and has worked on other machines previously).  Once I downloaded it, I moved it into C:/inetpub/wwwroot/code/main.asp

I am a bit of a novice at this!  But I am hoping someone can point me in the right direction!


I get the following error when I try and run the web application through IE:

"An error occurred on the server when processing the URL. Please contact the system administrator. If you are the system administrator please click here to find out more about this error."

(When i click the "click here" button it just goes to the IIS site).


Appreciate any help I can get!

Any idea on how to perform this?





C# / Java webservice


I am writting a client applicatin that acesses a webservice written by another company.  I need to test against this webservice but since it is live I need another place to test with.  I don't have access to the code from the webservice but have added a reference to my project.  I would like to create a test platform using C# which will run on IIS and not Java.

I have created a basic webserive using both the NetBeans platform and the VS/C# platform.  The problem I am having is if I dynamically change the web address from one to the other my client application complains that the webservice is invalid.  I have verified all the calls are the same.

Are there any setting with VS/C# that allow me to configure it to behave more like the Java webservice?  I don't have the server support to host the Java application for full testing along with other problems using the Java version.

I have run both services in the "WCF Test Client" and can see where the WCF service uses the varibles for request and the Java uses body/request but can't get the WCF to follow that format.  I read somewhere about changing the OperationContract with SoapRpcMethod but then the mentod is not longer exposed. I also tried a Web Service in .NET 3.5 instead of a WCF server but that seems to be more trouble and does not
