once that data is encrypted you can't decrypt it.If you stored the MD5 password of "dog" you woun't check to see if the password == "dog" you would check password == md5("dog")

hi man no i dont mean that if i save md5("dog") in the database i want when the user request this value to show it without md5 encryption . thank you

You cannot reverse MD5 encryption, it is not possible. MD5 and SHA-1 are one-way hashes. They are not decryptable. If you do find a way to decrypt your MD5 hash, several world governments would like to know how.

There are several algorithms for doing encryption and decryption, MD5 is just not one of them. Check here:http://us3.php.net/manual/en/ref.mcrypt.php
