Method Detail

initialize

public void initialize(AlgorithmParameterSpec algorithmParameterSpec,
                       SecureRandom random)
                throws InvalidAlgorithmParameterException

Initializes the key pair generator using the specified parameter set and source of randomness. If the parameter set is true, the implementation defaults to SLHDSAAlgorithmParameterSpec, Furthermore, if source random is null, the implementation defaults to the SecureRandom implementation of the JCE Provider.

Overrides:

initialize in class KeyPairGeneratorSpi

Parameters:

algorithmParameterSpec - algorithm parameter specification.

random - secure random.

Throws:

InvalidAlgorithmParameterException - if algorithmParameterSpec is not an instance of SLHDSAAlgorithmParameterSpec.

initialize

public void initialize(int keySize,
                       SecureRandom random)

Initializes this KeyPairGenerator with the given key size and PRNG.

Specified by:

initialize in class KeyPairGeneratorSpi

Parameters:

keySize - public key size in bits, corresponding to the NIST security levels 1, 3 and 5 respectively

random - source of randomness, if null, SecureRandom from the JCE Provider is used later on

Throws:

IllegalArgumentException - for invalid key size

generateKeyPair

public KeyPair generateKeyPair()

Generates a KeyPair consisting of a SLHDSAPrivateKey and SLHDSAPublicKey depending on the initialisation of this object. If SLHDSAKeyPairGenerator was not initialized, the implementation defaults to SLHDSAAlgorithmParameterSpec.

Specified by:

generateKeyPair in class KeyPairGeneratorSpi

Returns:

a KeyPair consisting of a SLHDSAPublicKey and a SLHDSAPrivateKey.
