Method Detail

getFixed

public static FixedSecureRandom getFixed(byte[] seed,
                                         int strength)

Return a seeded FixedSecureRandom representing the result of processing a CMCE test seed with the CMCE RandomNumberGenerator.

Parameters:

seed - original CMCE seed

strength - bit-strength of the RNG required.

Returns:

a FixedSecureRandom containing the correct amount of seed material for use with Java.
