+--javax.crypto.spec.DHGenParameterSpec
- public class DHGenParameterSpec
- extends java.lang.Object
- implements java.security.spec.AlgorithmParameterSpec
This class specifies the set of parameters used for generating
Diffie-Hellman (system) parameters for use in Diffie-Hellman key
agreement. This is typically done by a central
authority.
The central authority, after computing the parameters, must send this
information to the parties looking to agree on a secret key.
