DES Encryption: Looking for results for each round of encryption/decryption to debug code I've been searching for a few days in different forums trying to find an example of DES that gives the key/output values for all 16 layers. I found one that gives the encryption which helped me fix that part, but my decryption isn't working correctly. It's easier to debug if I know what I'm aiming for.
Is there someplace that has all the encryption/decryption round outputs that I can look at?
Should they be the same only backward? Decryption round 1 output = encryption round 16 output?
Thank you for any help you can give.

Yes, that is correct; the decryption subkeys are exactly the encryption subkeys in the opposite order.
I don't have the per-round test vectors you were asking for, but I can make this suggestion: if you have DES working in the encrypt direction, you can generate the test vector yourself; recording the state of the block after each round.  Then, when you attempt to decrypt the block, the per-round block state is supposed to traverse the same path backwards; for example, if the block state after encryption round 15 was X, then the block after after decryption round 1 should also be X.  If decryption isn't working, then somewhere during the cipher it went wrong; by looking at the per-round states, you should be able to narrow it down to a specific round.
