<PRE><?

srand ((double) microtime() * 1000000);

for ($i=0;$i<100;$i++) {
        $rand = rand();     
        echo $rand;
# try this script with and without the next line commented
#       echo ":".crypt($rand);
        echo "\n";
} 

?></PRE>

Also, crypt() seems to always use "i3" as a salt.  I'm guessing this is somehow related.
