Class DHParameterSpec

public class DHParameterSpec extends Object implements AlgorithmParameterSpec

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.

Since: 1.4

Constructor Summary
	DHParameterSpec(BigInteger p, BigInteger g) Create a new set of Diffie-Hellman parameters.
	DHParameterSpec(BigInteger p, BigInteger g, int l) Create a new set of Diffie-Hellman parameters.

Method Summary
BigInteger	getG() Get the base generator, g.
int	getL() Get the length of the private exponent, in bits.
BigInteger	getP() Get the prime modulus, p.

Constructor Detail

public DHParameterSpec(BigInteger p, BigInteger g)

Create a new set of Diffie-Hellman parameters.

Parameters: p The prime modulus. g The base generator.

public DHParameterSpec(BigInteger p, BigInteger g, int l)

Create a new set of Diffie-Hellman parameters.

Parameters: p The prime modulus. g The base generator. l The size of the private exponent, in bits.

public BigInteger getG()

Get the base generator, g.

Returns: The base generator g.

public int getL()

Get the length of the private exponent, in bits.

Returns: The length of the private exponent, in bits, or 0 if this has not been explicitly set.

public BigInteger getP()

Get the prime modulus, p.

Returns: The prime modulus, p.
