You can for forget about salt and all that perl stuff and use openssl to generate the crypt. Openssl will add the salt for you. Just type $ openssl passwd Password: lu0t78Vw2b8XA and enter your password, a crypt will be generated. This will be a DES crypt. To generate a MD5 crypt. $ openssl passwd -1 Password: $1$yHhBvaFG$E.i/guQr.NFcoXuyOnIiN. You can also read your passwords in from a file if that is useful to you. $ openssl passwd -help Usage: passwd [options] [passwords] where options are -crypt standard Unix password algorithm (default) -1 MD5-based password algorithm -apr1 MD5-based password algorithm, Apache variant -salt string use provided salt -in file read passwords from file -stdin read passwords from stdin -quiet no warnings -table format output as table -reverse switch table columns Steve On Mon, 13 Jan 2003, Cipriano Groenendal wrote: > > > THIS IS A BADLY WRITTEN SCRIPT.
