Constructor Summary

DESKeyGenerator()

Method Summary

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 64 bits in size, otherwise strength can be 64 or 56 bits (if you don't count the parity bits).
