Modifier and Type	Method and Description
byte[]	generateKey() generate a secret key.
void	init(KeyGenerationParameters param) initialise the key generator - if strength is set to zero the key generated will be 192 bits in size, otherwise strength can be 128 or 192 (or 112 or 168 if you don't count parity bits), depending on whether you wish to do 2-key or 3-key triple DES.
