  1. My account information was stolen after the hack https://forums.phpfreaks.com/topic/298874-alert-the-phpfreaks-forum-members-data-appears-to-have-been-stolen/ But it appears there is no way to delete my account now? I don't want to be a member of this group anymore. How do I delete my account?
  2. I did some research on hashing, and it looks like both md5() and sha1() can be reversed, given enough time and processing power. I wrote a function that (I think) would make it considerably more difficult to unhash a value. Do you think this is overkill? Are there any problems that jump out at you? Here is the code: <?php function hyper_hash($value) { for ($i = 0; $i < 100; $i++) { if ($i %2 == 0) { $value = sha1($value); } else if ($i %3 == 1) { $value = base64_encode($value); } else { $value = md5($value); } } return $value; } $initial = microtime(true); echo "\"12345\" hashed to: " . hyper_hash("12345"). "<br /><br />"; $final = microtime(true); $delta = $final - $initial; echo "Time taken: " . $delta . " s"; ?>Here's a page with this code running: [removed] Thanks for the feedback, Zach
