From 9715ddcd2b2a3f3ed0f27398048191ac2de60c8b Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Fri, 5 Feb 2016 21:28:26 +0100 Subject: generate: have a default length of 25 Folks are lazy and don't want to type very much, so they'd like to have a default password length to generate that can be configured via environment variables per usual. I'm making the default 25. If the user forbids the use of symbols, pwgen will use a-zA-Z0-9, ensuring that at least one A-Z and at least one 0-9 is used. We want to have a password of at least 128-bits, so factoring in the issue with "at least one of this character type", 25 gets us there squarely. Signed-off-by: Jason A.
