Hi, as I mentioned previously the source for doing ECDH is available for both Java and C# at http://www.bouncycastle.org - look on the latest releases page for Java.

Dear David,
As you said that code for ECDH in java is available in bouncycastle.org.
I downloaded the bouncycastle package bcprov-jdk16-144 and tried to run the program but i am getting the following errors....

C:\Program Files\Java\jdk1.6.0_05\bin\bcprov-jdk16-144>javac BasicECDHExample.ja
va

C:\Program Files\Java\jdk1.6.0_05\bin\bcprov-jdk16-144>java BasicECDHExample
Exception in thread "main" java.security.NoSuchAlgorithmException: no such algorithm: ECDH for provider BC

at sun.security.jca.GetInstance.getInstance(GetInstan ce.java:190)
at java.security.KeyPairGenerator.getInstance(KeyPair Generator.java:237) at BasicECDHExample.main(BasicECDHExample.java:26)

How to solve this errors.....

Have a look at the source for the org.bouncycastle.jce.provider.test.DHTest You will find example code for using ECDH and ECDHC.

You can find the source in the .zip and .tar.gz versions.

The distributions are also available for anonymous ftp at ftp.bouncycastle.org Note the server does not support passive mode ftp.

Sorry, but I do not have the facilities to send the code via email.
