Solution 2

There are two open source libraries that claim to be able to generate DSA key pairs but using them is not for novices.

One is Beecrypt:

http://beecrypt.sourceforge.net/doxygen/c++/index.html[^]

The other is Crypto++:

http://www.cryptopp.com/[^]

This has many tutorials on the net including here on CP:

Compiling and Integrating Crypto++ into the Microsoft Visual C++ Environment[^]

If you utilize the .net framework then it is much easier:

I have already tried crypto++ and I'm able to generate 512 bit DSA keypair, but the length of privatekey x parameter is varies and also the values of PQG group parameters should be constant.

When coming to beecrypt, I'm unable to install it in windows7 platform.

Please, suggest me a way to overcome these problems.

Thanks for your reply.

Perhaps try here as you are already some way down the path.
