The crypt function is the traditional way of generating the hashed-password strings in /etc/passwd (or, these days, /etc/shadow). It's used in login.c to allow logins based on local passwords in addition to Kerberos passwords. Usually that function is in the standard C library; you don't say what type of OS you're on, but perhaps it's in another library there?
