public Class JPAKEPrimeOrderGroups

extends Object
Class Inheritance
Imports
java.math.BigInteger
Standard pre-computed prime order groups for use by J-PAKE. (J-PAKE can use pre-computed prime order groups, same as DSA and Diffie-Hellman.)

This class contains some convenient constants for use as input for constructing JPAKEParticipants.

The prime order groups below are taken from Sun's JDK JavaDoc (docs/guide/security/CryptoSpec.html#AppB), and from the prime order groups published by NIST.
