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.
