[oclug] Encryption methods (for Linux 2.2.12) and password salt questions

[Liam Gibbs]

Does anyone know what salt to use for encrypting strings in Linux 2.2.12? In an example of a password check, I know that generally the UNIX method is to take the first two characters of whatever the password is and use that as the salt. But that seems to be impossible with Linux 2.2.12, as it seems (by checking in /etc/passwd) that all of the passwords are x (not even two characters). I've tried 'x' as the salt, but this wasn't successful. It also seems strange to see that all of the passwords are x, and yet they're not all the same password. Something is up, but I can't quite tell. Can anyone help?

Thanks in advance,

Liam Gibbs
