createBlockDecryptor

public SingleBlockDecryptor<ElGamal.Parameters> createBlockDecryptor(AsymmetricKey key,
                                                                     ElGamal.Parameters parameters)

Description copied from interface: AsymmetricOperatorFactory

Create a block decryptor for the passed in key and parameter set.

Parameters:

key - the key to be used in the decryptor.

parameters - the parameter set for the decryptor.

Returns:

an initialised block decryptor for the passed in arguments.
