Method Detail

initialize

public void initialize(MessageDigest md)

Initialize the RNG with the given message digest.

Parameters:

md - the message digest for constructing the random numbers

nextSeed

public byte[] nextSeed(byte[] outSeed)

Compute the next seed value, return a random byte array, and update the seed to the next value.

Parameters:

outSeed - byte array in which (1 + inSeed + RAND) mod 2ⁿn will be stored

Returns:

byte array containing H(inSeed)
