Passwords and password cracking
- Should you use the terms "dehashing", "reversing", or "decrypting" when talking about password cracking? No - no, you should not.
- Systems that I use in my password research include 'irongiant' (hashcat benchmark, personal blog post) and a ZTEX 1.15y cluster running John the Ripper
- ken's Salty Rainbow is an archive of descrypt hashes for common non-personal passwords
- My hashcat activity on GitHub (mostly docs PRs, feature requests, and bug reports)
- My convenience mirror of MDXfind - a highly efficient, multi-iteration/nested hashing tool
- I am a moderator of the hashcat forums
- I am a moderator of the Hashes.org Discord
- I contribute to the Security StackExchange on password and hashing topics
- I'm proud of this hashcat feature request for sha1crypt support
- Many of my GitHub gists are password-related
- Some of my publications and talks are password-related.
- Minimal true VeraCrypt FAT containers for hashcat testing
- 0x38b - an Alaskan password-hash puzzle - on a bumper sticker
