Forgot I already posted a ticket about this =)

Here's my suggestion for the password hashing detection.

The other patch is for the git HEAD, and the other one for Tiger 3.2.3.

(file #26713, file #26714)

Yes, I noticed that this patch dates back a while. It was included to Tiger on may 2011. Should this still be reconsidered and improved?

Also the patch doesn't seem to support the rounds syntax. When you've defined SHA_CRYPT_*_ROUNDS in login.defs, the hash string starts with "$6$rounds=<integer>$"...

I can't remember the details anymore sorry, it's been more than a year since I proposed the patch.

Is the passwd="md5" intended, instead of passwd="sha512"? Other hashing algorithms could be added from man 3 crypt, such as 2a for Blowfish and 5 for SHA-256.

describes a scheme for using SHA512 in /etc/shadow. This is the default used in Debian GNU/Linux squeeze so we are getting a lot of false positives from tiger.

[ Kees Cook ]
  * debian/local/common-password, debian/pam-configs/unix: switch from "md5"
    to "sha512" as password crypt default.
