I sometime use something along these lines, which does pretty well (you can make it into a sub if you like).
#!/usr/bin/perl -w
my $gmtime =join '', gmtime;
my $time = time;
my $rand = rand time;
my @salt = ('.','/','A'..'Z',0..9,'a'..'z');
my $salt = join '', (@salt)[rand @salt, rand @salt];
my $uniquetempass = crypt( $gmtime.$rand.$time, $salt);
print 'gmtime ', $gmtime, "\n";
print 'time ',$time,"\n";
print 'rand ', $rand,"\n";
print 'salt ', $salt, "\n";
print $uniquetempass, "\n";

Disclaimer: Don't blame. It came from inside the void
perl -e "$q=$_;map({chr unpack qq;H*;,$_}split(q;;,q*H*));print;$q/$q;"
