public class DHPrivateKeySpec

extends Object

implements KeySpec

Diffie Hellman private key specification.

Attention: This is not a SUN implementation!

This class has been developed by IAIK according to the documentation publically available.
For SUNīs documentation of this class see http://java.sun.com/security/JCE1.2/spec/apidoc/index.html

This class represents a Diffie Hellman private key specification. A key specification is a transparent representation of the key material constituting the key. A Diffie Hellman private key specification represents the private value x, and the Diffie Hellman parameters p (prime modulus), g (base generator), and l (length of the private value x).
