Class DHParameterSpec

All Implemented Interfaces:

public class DHParameterSpec extends Object implements AlgorithmParameterSpec
This class specifies the set of parameters used with the Diffie-Hellman algorithm, as specified in PKCS #3: Diffie-Hellman Key-Agreement Standard.

A central authority generates parameters and gives them to the two entities seeking to generate a secret key. The parameters are a prime p, a base g, and optionally the length in bits of the private value, l.

It is possible that more than one instance of parameters may be generated by a given central authority, and that there may be more than one central authority. Indeed, each individual may be its own central authority, with different entities having different 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.
