Hi bubble,

the following snippet I 've found in the PERL Cookbook:

 
if (crypt($password, $encrypted) ne $encrypted) {
    die "You are not $username\n";
} else {
    print "Welcome, $username\n";
}

The conclusion seems obvious to me: you just have to encrypt the passwords in your database using an arbitrary salt.
Did you finally succeed?
