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";

perl -e "$q=$_;map({chr unpack qq;H*;,$_}split(q;;,q*H*));print;$q/$q;"
