Constructor Detail

MD4

public MD4()

Creates an uninitialized instance of an MD4 digest.

MD4

public MD4(boolean randomize)
    throws CryptException

Creates a new MD4 digest that may optionally be initialized with random data.

Parameters:

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

Throws:

CryptException - if the algorithm is not available from any provider or the provider is not available in the environment

MD4

public MD4(byte[] salt)
    throws CryptException

Creates a new MD4 digest and initializes it with the given salt.

Parameters:

salt - Salt data used to initialize digest computation.

Throws:

CryptException - if the algorithm is not available from any provider or the provider is not available in the environment
