Class Poly1305KeyGenerator

java.lang.Object

javax.crypto.KeyGeneratorSpi

iaik.security.mac.Poly1305KeyGenerator

public class Poly1305KeyGenerator
extends VarLengthKeyGenerator

This class provides the functionality of KeyGenerator for generating 256 bit keys to be used by the Poly1305 authenticator.

An application uses

 KeyGenerator key_gen = KeyGenerator.getInstance("Poly1305", "IAIK");
 

for creating a KeyGenerator object for the Poly1305 algorithm. For actually generating the requested secret key from the KeyGenerator object just created, an application calls the generateKey method after having initialized the generator with some random seed or relied on the default system-provided source of randomness:

 SecretKey key = key_gen.generateKey();
