[comp.unix.questions] shadow...

AGRISCS@umcvmb.missouri.edu (Don Ingli) (01/02/90)

First of all, let me apologize for my last posting, I ran it through a
speller/sentence restructurer that I am TRYING to write :-) and it did a good
job of chopping up my sentences.

What good is shadow??  Well the permissions for the shadow file are

-r-------- 1 root    sys     2267 Dec 21 14:49 /etc/shadow

Root owns it and ONLY root can read it... thus no user can read it for
encryption/decryption routines.  This is a secure way for your machine
to keep the hackers out of the passwds.

To create this 2-file passwd scheme, look up the man page  pwconv(1M).

This is SYS V ..  does anyone know if BSD has this also??

  BSD 4.3 doesn't have a shadow password scheme.  However, it is
included (and optional, I believe) in BSD 4.4.
