Public & Private Keys in .NET besides RSA

Question

Hi All,

Am I missing something obvious here (I hope I am), besides RSA, are there any other crypto methods in .NET that use a public & private key?

Thanks!

Answer 1

• DSA
• ECDiffieHelman (Contrary to MSDN docs, not supported on Windows XP)

Answer 2

http://en.wikipedia.org/wiki/Public-key_cryptography#Examples

Answer 3

Rsa is derived from the class AsymmetricAlgorithm

From there, MSDN lists the following derived classes:

System.Security.Cryptography.DSA
System.Security.Cryptography.ECDiffieHellman
System.Security.Cryptography.ECDsa
System.Security.Cryptography.RSA

Answer 4

No. You are not missing anything. RSA appears to be the only public key encryption scheme implemented in .NET. DSA and ECDSA are signature schemes and Diffie-Hellman is a key agreement scheme.
