When did UNIX start using encrypted passwords, and not displaying passwords when you type them in?
I've been using various versions of UNIX and Linux since 1993, and I've never run across one that showed your password as you type it in when you log in, or one that stored passwords in plain text rather than encrypted. I'm writing a script for work for a security audit, and two of the requirements are that passwords not be displayed when you type it as you log in, and that passwords not be stored in clear text. Can anyone point me to some documentation saying either that UNIX has never done those things, or when UNIX (AIX, specifically, but other flavors might be helpful later on) stopped doing those things?
