All, I need to exchange DH public keys with a Java servlet. This servlet uses the Sun JCE provider for its crypto stuff. I'm obviously using Crypto++.
I can get the DH public key into a SecByteBlock using GenerateKeyPair (). However, Java encodes its DH public keys using the X.509 SubjectPublicKeyInfo standard - as far as I can tell. So, I need to do the same. Here is the question; how the hell do I get a DH public key encoded in the same format? I've trawled the doxygen manual and have found hints: DEREncode () - what does this do exactly? Encode the entire 'this' object? Encode the public key only? If so does it comply to X.509 SubjectPublicKeyInfo? The inherited AccessMaterial or GetMaterial methods of a DH object. The X509PublicKey class - but this seems to be a pure virtual/abstract class so I can't instantiate it. Any help would be gratefully appreciated!
