Need DSA (Digital Signature Algorithm) to authenticate incoming msgs or digitally sign outgoing msgs.  Already have a private & public key set.  Messages are incoming our outgoing messages being sent across Ethernet.  Must be able to generate a signature with a private key for outgoing msgs or authenticate incoming msgs with a public key.

Hi,

Can you explain in more detail what you are looking for?  Are you looking for a pre-written library of code, or just algorithms?

DSA (Digital Signature Algorithm) is part of the SSL standard.  I'm looking for some utilities to add signatures to the end of outgoing messages(small data stream) or authenticate incoming messages. This algorithm uses private & public keys for the authentication process.
