DHParameterSpec

open class DHParameterSpec : AlgorithmParameterSpec

kotlin.Any
↳	javax.crypto.spec.DHParameterSpec

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.

Summary

Public constructors
DHParameterSpec(p: BigInteger!, g: BigInteger!) Constructs a parameter set for Diffie-Hellman, using a prime modulus p and a base generator g.
DHParameterSpec(p: BigInteger!, g: BigInteger!, l: Int) Constructs a parameter set for Diffie-Hellman, using a prime modulus p, a base generator g, and the size in bits, l, of the random exponent (private value).

Public methods
open BigInteger!	getG() Returns the base generator g.
open Int	getL() Returns the size in bits, l, of the random exponent (private value).
open BigInteger!	getP() Returns the prime modulus p.
