Thread: Brute-force with only half of the cipher text
Post: RE: Brute-force with only half of the cipher text
| You don't have enough information to be able to recover a key.

Thread: Candidate definition
Post: RE: Candidate definition
| In the context of my question, an "invalid" key doesn't just mean the wrong key for my hash - it means a key that cannot be used with the DES cipher..

Post: RE: Error with estimated time
| Cheers @philsmd - I went to test it and run into another issue preventing -m 14000 from working, so I raised it as an issue in Github.
Thanks! |
