javax.crypto.KeyGeneratorSpi

iaik.security.cipher.CAST128KeyGenerator

public class CAST128KeyGenerator
extends VarLengthKeyGenerator

This class provides the functionality of KeyGenerator for generating keys to be used by the CAST128 cipher.

An application uses

 KeyGenerator key_gen = KeyGenerator.getInstance("CAST128");
 

for creating a KeyGenerator object for the CAST128 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 new_key = key_gen.generateKey();
