From the man page of the crypt that I have here:

================================================================================
GNU EXTENSION
The glibc2 version of this function has the following additional
features. If salt is a character string starting with the three
characters "$1$" followed by at most eight characters, and optionally
terminated by "$", then instead of using the DES machine, the glibc
crypt function uses an MD5-based algorithm, and outputs up to 34 bytes,
namely "$1$<string>$", where "<string>" stands for the up to 8
characters following "$1$" in the salt, followed by 22 bytes chosen
from the set [a-zA-Z0-9./]. The entire key is significant here
(instead of only the first 8 bytes).

Programs using this function must be linked with -lcrypt.

CONFORMING TO
SVID, X/OPEN, 4.3BSD, POSIX 1003.1-2001
================================================================================

Well... I suppose DES is not Enigma, but I may be wrong. I just quoted this
"extension" because it shows both algorithms used here.
