public interface BasicAgreement

The basic interface that basic Diffie-Hellman implementations conforms to.

Method Summary

java.math.BigInteger	calculateAgreement(CipherParameters pubKey) given a public key from a given party calculate the next message in the agreement sequence.
int	getFieldSize() return the field size for the agreement algorithm in bytes.
void	init(CipherParameters param) initialise the agreement engine.

getFieldSize

public int getFieldSize()

return the field size for the agreement algorithm in bytes.

calculateAgreement

public java.math.BigInteger calculateAgreement(CipherParameters pubKey)

given a public key from a given party calculate the next message in the agreement sequence.
