Method Detail

engineInit

protected void engineInit(java.security.spec.AlgorithmParameterSpec params,
                          java.security.SecureRandom random)
                   throws java.security.InvalidAlgorithmParameterException
Description copied from class: KeyGeneratorSpi
Initializes the key generator with the specified parameter set and a user-provided source of randomness.
Overrides:
engineInit in class KeyGeneratorSpi
Following copied from class: javax.crypto.KeyGeneratorSpi
Parameters:
params - the key generation parameters
random - the source of randomness for this key generator
Throws:
java.security.InvalidAlgorithmParameterException - if params is inappropriate for this key generator

engineInit

protected void engineInit(java.security.SecureRandom random)
Description copied from class: KeyGeneratorSpi
Initializes the key generator.
Overrides:
engineInit in class KeyGeneratorSpi
Following copied from class: javax.crypto.KeyGeneratorSpi
Parameters:
random - the source of randomness for this generator

engineInit

protected void engineInit(int keySize,
                          java.security.SecureRandom random)
Description copied from class: KeyGeneratorSpi
Initializes this key generator for a certain keysize, using the given source of randomness.
Overrides:
engineInit in class KeyGeneratorSpi
Following copied from class: javax.crypto.KeyGeneratorSpi
Parameters:
keysize - the keysize. This is an algorithm-specific metric, specified in number of bits.
random - the source of randomness for this key generator.
Throws:
java.security.InvalidParameterException - if keysize is wrong or not supported.

engineGenerateKey

protected SecretKey engineGenerateKey()
Description copied from class: KeyGeneratorSpi
Generates a secret key.
Overrides:
engineGenerateKey in class KeyGeneratorSpi
Following copied from class: javax.crypto.KeyGeneratorSpi
Returns:
the new key.
