5 years ago - Unsecure Tripcodes (!xxx from #xxx) Exmaple: this old gem
- Secure Tripcodes (!! from ##xxx) Each board has its own salt
- Double Tripcode (!xxx!xxx from #xxx#xxx) (possibly) Legacy feature that could be revived See http://4-ch.net/dqn/kareha.pl/1160523823/ and https://dollars-bbs.org/test/res/1325934865.html and https://www.lurkmore.com/view/Tripcode
- Possible source code https://pastebin.com/4JVjS02b
- Tripphrases (as in http://worrydream.com/tripphrase/) Possible new “easter egg feature” at least 12 bits of info per word
- Hash methods Traditionally DES crypt() Modern boards use MD5 or SHA1
- Character encodings Traditionally, a mutated type of shift-JIS Modern board uses UTF8
- Hash length by truncation Traditionally 8 Base64 characters (48bits) Modern board uses 10~12 (60~72bits) See tripphrases
