Hi guys,
 I am new to this cryptography thing.This is what I need to do ..
The system uses public key encryption .So I need to generate the Public key
and private key pair and send the public key to the other party.The key has
to be a 1024 RSA key.
The party has given me their public key and they want me to use DES3
encryption to encrypt the file and send it to them.
I was reading the documentation on MSDN
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/htm
l/cpconencryptingdecryptingdata.asp

and it mentions that .NET supports only Digital Signature Algorithm and RSA
for public key encryption.So does it mean that using a .NET solution is out
of question. If so could any one guide on the alternatives.

Any help or advice in this matter would be greatly appreciated.
Thanks in advance

James
