Class DHPublicKeySpec

  1. java.lang.Object
  2. extended byjavax.crypto.spec.DHPublicKeySpec
All implemented interfaces:
java.security.spec.KeySpec

  1. public class DHPublicKeySpec
  2. extends java.lang.Object
  3. implements java.security.spec.KeySpec
This class specifies a Diffie-Hellman public key with its associated parameters.

Note that this class does not perform any validation on specified parameters. Thus, the specified values are returned directly even if they are null.
