java.lang.Objectjavax.crypto.spec.DHParameterSpec
public class DHParameterSpec
The base set of parameters necessary to perform Diffie-Hellman key exchange. Each party in the key exchange shares these parameters.
Each set of parameters consists of a base generator
g
, a prime modulus p
, and an
optional length, in bits, of the private exponent.
See PKCS #3 - Diffie-Hellman Key Agreement Standard for more information.
