Interface URoutine

public interface URoutine

Custom routine interface for computing 'u' as 'H(A | B)'.

If you don't want to employ the default routine for computing 'H(A | B)' message you can use this interface to define your own. Remember to make sure that exactly the same routine is used by both client and server session, else authentication will fail.

java.math.BigInteger	computeU(SRP6CryptoParams cryptoParams, URoutineContext ctx) Computes 'u' as 'H(A | B)'.

Method Detail

computeU

java.math.BigInteger computeU(SRP6CryptoParams cryptoParams,
                              URoutineContext ctx)

Computes 'u' as 'H(A | B)'.

Parameters:

cryptoParams - The crypto parameters for the SRP-6a protocol.

ctx - Snapshot of the SRP-6a client session variables which may be used in the computation of the hashed keys message.

Returns:

The resulting 'u' as 'H(A | B)'.
