----
hkmaly has updated his crypt/decrypt code at http://adela.karlin.mff.cuni.cz/~hkmaly/crypt_using_md5.php.txt
and made a sha1 version.
Note that if you crypt_md5 twice, you get back the first 16 characters.
<?
$time= 1110039695; // time();
$key= "secret key";
print crypt_md5(crypt_md5('This is a very long etc.',$key,$time),$key,$time);
?>
Produces:
This is a very lfkãµìÄcÜ
The same is true for decrypt_md5, and for the _sha1 versions. (The $time parameter is new. Remove
it if you're using the old code.)
You can assess whether this would be a problem in your own situation.
