SHA512

public SHA512(boolean randomize)

Creates a new SHA512 digest that may optionally be initialized with random data.

Parameters:

randomize - True to randomize initial state of digest, false otherwise.

SHA512

public SHA512(byte[] salt)

Creates a new SHA512 digest and initializes it with the given salt.

Parameters:

salt - Salt data used to initialize digest computation.
