In hashtable.

On modern systems, /etc/shadow.

what hashing function does eunchs use

man crypt, and see the "Notes" section.

Oldschool Unix uses plain ol' DES; most systems use MD5 nowadays I think.

And on BSD, it's /etc/master.passwd

Things are sometimes very different from one system to another.

wrong, wrong, wrong. modern UNIX systems can store passwords in a variety of places using a variety of methods if they are even configured to use passwords at all. Pluggable Authentication Modules¹ are used by the most popular UNIX or unixlike systems including Solaris, Mac OS X, Linux, and FreeBSD...

With PAM, the passwords don't have to be hashed or even stored locally - they might come from LDAP or Active Directory, or maybe users are authenticated using SMB, or NIS, or whatever. Or the system could be configured not to use passwords but instead some other authentication mechanism.

of course, when your computing experience is limited to your mom's basement, you probably don't see any of these kinds of configurations.

The fact that passwords can come from a variety of sources doesn't mean the other posts are wrong.
And I have an LDAP server in my mom's basement which stores its passwords in /etc/passwd, so go fuck yourself.

The passwords can be anywhere.

There is no standard way to find these locations.

You will have to do like all *nix fags. Read a poorly written Wiki and hope there is a passing mention of what you are looking for.

Your odds are not in your favor though.

PAM is the authentication system standard and is specified by X/Open Single Sign-on Service (XSSO)¹. The standard way to find out where passwords are being stored is to interpret the PAM configuration.

This shit is thirteen years old. I can't be the only one that knows about this on here...

Everyone knows about PAM, but you're the only person here arrogant enough to think it could come as a revelation to everyone else. >>16 is a Windows user and a transparent troll.

I recently set up PAM with RADIUS to provide two-factor authentication. This was just a proof of concept though and I don't actually use it

Someone is confusing how passwords are stored with how they are served.

Wow. I did exactly that circa 2000, except it was for work / production.
