64 DES full example with all the stages I'm trying to write a code to perform encryption and decryption of 64-bit DES but I'm having a problem in verifying that my code is working correctly. My graduation project is about DES crypt-analysis so I'm trying to implement DES to generate the pairs used in the attack.

Can anyone give me an example on encryption of DES with all stages?

For instance, I would like to see the key schedule and the values of all 16 round keys generated by the input key.
Might I suggest the "DES cipher internals in Excel" page by Nayuki? Because everything's in Excel, all the internal values are openly displayed.
