[RESOLVED] need a encryption function other than md5()

toxic_brain

i am passing an SQL string with url to a serach result display pageand retrieve it using $_GET. but i don't want to view it on the address bar as plain text.
can u suggest any simple algorithm to encrypt and decrypt it.
i am not able to use md5() since it does not have decryption.

See if you have mcrypt installed (use phpinfo() to find out). If you have that installed then use code similar to this:

Otherwise, if you have PEAR installed, then you can use the blowfish encryption class which doesn't need mcrypt installed:
http://pear.php.net/package/Crypt_Blowfish

And if you don't have PEAR installed then you'll have to come up with one of your own functions. Here's is one:
