Field Summary

static int

MISTY1_KEY_SIZE The Misty1 key size (16 bytes)

Constructor Summary

Misty1KeyGenerator()

Method Summary

SecretKey	generateKey() Generate a Misty1 key.
void	init(AlgorithmParameterSpec params, SecureRandom random) Since Misty1 keys are of a fixed size and do not require any parameters, this method only sets the source of randomness.
void	init(int strength, SecureRandom random) Since Misty1 keys are of a fixed size, this method only sets the source of randomness.
void	init(SecureRandom random) Initialize the key generator with the given source of randomness.

Method Detail

init

public void init(AlgorithmParameterSpec params,
                 SecureRandom random)

Since Misty1 keys are of a fixed size and do not require any parameters, this method only sets the source of randomness.

Overrides:

init in class SecretKeyGenerator

Parameters:

params - the parameters (not used)

random - the source of randomness

init

public void init(int strength,
                 SecureRandom random)

Since Misty1 keys are of a fixed size, this method only sets the source of randomness.

Overrides:

init in class SecretKeyGenerator

Parameters:

strength - the key strength (not used)

random - the source of randomness for this key generator

init

public void init(SecureRandom random)

Initialize the key generator with the given source of randomness.

Overrides:

init in class SecretKeyGenerator

Parameters:

random - the source of randomness

generateKey

public SecretKey generateKey()

Generate a Misty1 key.

Overrides:

generateKey in class SecretKeyGenerator

Returns:

the generated Misty1Key
