>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. -- Jorge Godoy <[EMAIL PROTECTED]> ---------------------------(end of broadcast)--------------------------- TIP 9: In versions below 8.0, the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
