public class RCxKeyGenerator

extends VarLengthKeyGenerator

This class provides the functionality of KeyGenerator for generating keys to be used by the RC2 and RC4 ciphers.

An application uses

 KeyGenerator key_gen = KeyGenerator.getInstance("RC2");
 

respectively

 KeyGenerator key_gen = KeyGenerator.getInstance("RC4");
 

for creating a KeyGenerator object for the RC2/RC4 algorithm. For actually generating the requested secret TripleDES 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 rcx_key = key_gen.generateKey();
