public class PFlashKeyPairGenerator

extends KeyPairGenerator

This class implements key pair generation of the pLASH signature scheme.

The PFlashKeyPairGenerator can be used as follows:

Key generation:

1. get instance of pFLASH key generator
   KeyPairGenerator kpg = Registry.getKeyPairGenerator("pFLASH");
2. initialize generator with "default" set of parameters
   kpg.initialize(null, secureRandom);
3. generate keys
   KeyPair keys = kpg.genKeypair();

initialize

public void initialize(int keysize,
                       SecureRandom srandom)

Initialize the key pair generator. (not supported)

Overrides:

initialize in class KeyPairGenerator

Parameters:

keysize -

srandom -

initialize

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

Description copied from class: KeyPairGenerator

Initialize the key pair generator using the specified parameter set and the SecureRandom implementation of the highest-priority installed provider as the source of randomness. (If none of the installed providers supply an implementation of SecureRandom, a system-provided source of randomness is used.).

Overrides:

initialize in class KeyPairGenerator

Following copied from class: de.flexiprovider.api.keys.KeyPairGenerator

Parameters:

params - the parameter set used to generate the keys

random - a source of randomness

Throws:

InvalidAlgorithmParameterException - if the given parameters are inappropriate for this key pair generator.

genKeyPair

public KeyPair genKeyPair()

Generate a pFLASH key pair, consisting of a PFlashPublicKey and a PFlashPrivateKey.

Overrides:

genKeyPair in class KeyPairGenerator

Returns:

the generated key pair
