public class MeRSAKeyPairGenerator

extends KeyPairGenerator

This class is used to generate key pairs for the multi-exponent RSA algorithms. It can be initialized with an instance of MeRSAKeyGenParameterSpec or with the bit length of the modulus n. The default bit length of the modulus is 1024.

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 MeRSAKeyGenParameterSpec.

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 prime p

secureRand - the source of randomness.

genKeyPair

public KeyPair genKeyPair()

Generate a MeRSA key pair, consisting of a MeRSAPrivateKey and an RSAPublicKey.

Overrides:

genKeyPair in class KeyPairGenerator

Returns:

the generated key pair
