/etc/shadow hash changes?
Hi, I was just messing around, and I realized that the new accounts I've created on my system have a much longer hash, and begin with $6$ instead of $1$ like my older useraccounts that havn't had their passwords changed in awhile. What's the reason for this, and what does it mean? What do the cooresponding $1$ and $6$ mean, and whatever other values might be there?

Hi.
The $X$ string tells crypt what hash to use - $1$ is MD5. $5$ and $6$ are SHA, presumably SHA-1 and SHA2 respectively, although I can't find any documentation which is particularly helpful (googleing for strings like $6$ doesn't get much joy).
