	Generate passwords on #OpenBSD romanzolotarev.com/bin/pass_new /dev/urandom + tr + fold + head [:alnum:] is 5.954 bits of entropy per char, so 20 chars is safe for pretty everything ;) pic.twitter.com/wtKRdQ4ntR

	Replying to @romanzolotarev Many sites won’t let you in without a “special” char in the password. I remember seeing similar but “better” script on z3bra.org’s gopher site

	Replying to @bnastic 1. Close the browser tab and clear the history. Never visit those sites again. 2. Better? No way :) <3 z3bra.org

	Replying to @bnastic Hmm, okay.jpeg ' -~' vs [:alnum:] aren't the same head -1 vs sed 1q, really?

	Replying to @romanzolotarev I just copied the line verbatim. The ‘ -~’ is the important difference. Despite you not liking it, I can’t dictate what password policy services want to enforce.

You can also stack characters you want to allow: $ tr -cd [:alnum:][:punct:] < /dev/urandom | fold -w 20 | head -1 or just specific characters like comma, period, and underscore: $ tr -cd [:alnum:]',._' < /dev/urandom | fold -w 20 | head -1

	Replying to @gumnos @bnastic Or just $ tr -cd [:print:] ...

	Replying to @romanzolotarev @bnastic Or that, but more showing the set-composability aspect 😉
