JPAKEPrimeOrderGroups (Bouncy Castle Library 1.52 API Specification)

org.bouncycastle.crypto.agreement.jpake

## Class JPAKEPrimeOrderGroups

- java.lang.Object
- - org.bouncycastle.crypto.agreement.jpake.JPAKEPrimeOrderGroups

-     public class JPAKEPrimeOrderGroups
      extends java.lang.Object

  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 `JPAKEParticipant`s.

  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.
