Constructor Summary

GnuDHPrivateKey(java.math.BigInteger q, java.math.BigInteger p, java.math.BigInteger g, java.math.BigInteger x)           Convenience constructor.

GnuDHPrivateKey(int preferredFormat, java.math.BigInteger q, java.math.BigInteger p, java.math.BigInteger g, java.math.BigInteger x)           Constructs a new instance of GnuDHPrivateKey given the designated parameters.

 

Method Summary
boolean	equals(java.lang.Object obj)           Returns true if the designated object is an instance of javax.crypto.interfaces.DHPrivateKey and has the same parameter values as this one.
byte[]	getEncoded(int format)           Returns the encoded form of this private key according to the designated format.
java.math.BigInteger	getX()           Returns the private value x.
static GnuDHPrivateKey	valueOf(byte[] k)           A class method that takes the output of the encodePrivateKey() method of a DH keypair codec object (an instance implementing gnu.java.security.key.IKeyPairCodec for DH keys, and re-constructs an instance of this object.
