A Brief History of Password Storage, Transmission, and Cracking
- jhallenworld 11y agoOne of the first things we did at school when we first saw the UNIX source code was to optimize DES to make a good password cracker (I remember the one used by the library was very badly written). It was then so easy to try /usr/dict/words on the then non-hidden password file.
- vezzy-fnord 11y agocrack was the standard of its day, could it have been that? (https://en.wikipedia.org/wiki/Crack_%28password_software%29 https://en.wikipedia.org/wiki/Crack_%28password_software%29)
- jhallenworld 11y agoNo, we wrote our own. It's not hard.
- grymoire1 11y agoAs I recall, Matt Bishop and Dan Klein made significant contributions to research regarding bulk password cracking. "Improving System Security via Proactive Password Checking" (1992) http://www.klein.com/dvk/publications/passwd-matt-final.pdf http://www.klein.com/dvk/publications/passwd-matt-final.pdf Matt was the one who speed up DES cracking, and Dan Klein developed rules for cracking based on dictionaries. They should be acknowledged, IMHO.
