Method Detail
-
init
public void init(CipherParameters param)
initialise the EC Elgamal engine.- Specified by:
init
in interfaceECPairTransform
- Parameters:
param
- the necessary EC key parameters.
-
transform
public ECPair transform(ECPair cipherText)
Transform an existing cipher text pair using the ElGamal algorithm. Note: the input cipherText will need to be preserved in order to complete the transformation to the new public key.- Specified by:
transform
in interfaceECPairTransform
- Parameters:
cipherText
- the EC point to process.- Returns:
- returns a new ECPair representing the result of the process.
