Constructor Detail

SHA1

public SHA1()

Creates an uninitialized instance of an SHA1 digest.

SHA1

public SHA1(boolean randomize)

Creates a new SHA1 digest that may optionally be initialized with random data.

Parameters:

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

SHA1

public SHA1(byte[] salt)

Creates a new SHA1 digest and initializes it with the given salt.

Parameters:

salt - Salt data used to initialize digest computation.
