Overrides:

init in class SecretKeyGenerator

Parameters:

keySize - the key size

random - the source of randomness

init

public void init(SecureRandom random)

Initialize the key generator with the default parameters and the given source of randomness.

Overrides:

init in class SecretKeyGenerator

Parameters:

random - the source of randomness

generateKey

public SecretKey generateKey()

Generate a new PBEKey.

Overrides:

generateKey in class SecretKeyGenerator

Returns:

the generated PBEKey
