GMKeyPairGenerator

public GMKeyPairGenerator()

Method Details

initialize

public void initialize(int key_size,
 SecureRandom random)

Initializes the key pair generator with the specified key size and random number generator.

Specified by:

initialize in class KeyPairGeneratorSpi

Parameters:

key_size - The size of the key to generate (in bits). Must be at least KEY_SIZE.

random - The secure random number generator to use (currently unused in this implementation).

Throws:

IllegalArgumentException - If the key size is less than KEY_SIZE.

generateKeyPair

public KeyPair generateKeyPair()

Generates a key pair for the Goldwasser-Micali encryption scheme.

Specified by:

generateKeyPair in class KeyPairGeneratorSpi

Returns:

A KeyPair containing the public and private keys.
