public class MpRSAKeyPairGenerator

extends KeyPairGenerator

This class extends the KeyPairGenerator class. A key pair consists of a MpRSAPubKey and a MpRSAPrivKey.

The default bit length of n is 1024 bits and the default number of prime is 3.

MpRSAKeyPairGenerator

public MpRSAKeyPairGenerator()

Method Detail

initialize

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

Initialize the key pair generator with the given parameters and source of randomness. If the parameters are null, the default parameters are used.

Overrides:

initialize in class KeyPairGenerator

Parameters:

params - the parameters

random - the source of randomness

Throws:

InvalidAlgorithmParameterException - if the parameters are not an instance of MpRSAKeyGenParameterSpec.

initialize

public void initialize(int keySize,
                       SecureRandom secureRand)

Initialize the key pair generator with the given key size and source of randomness.

Overrides:

initialize in class KeyPairGenerator

Parameters:

keySize - the bit length of the modulus n

secureRand - the source of randomness

genKeyPair

public KeyPair genKeyPair()

Generate a new multi-prime RSA key pair, consisting of an MpRSAPrivateKey and an RSAPublicKey.

Overrides:

genKeyPair in class KeyPairGenerator

Returns:

the generated key pair
