Good work but minor bug?
by Dave , Earth, on Tuesday Sep 26, 2006
Thank-you for the source it was very helpful. One thing to note is that I believe there is a bug in the generate_sub_keys() routine. "input_key = c_block & d_block" needs to be added before running permuted_choice_2. (without this line the output is encrypted although it is not standard DES)
