1Why do you need it decrypted? Isn't a hash sufficent? – juergen d Mar 22 '12 at 12:41

To comapre when user enters the password while login i need to check and compare it with it one that is data base. Ya hash will be enough but how to do that? – adesh Mar 22 '12 at 12:46

A little search here on SO or on google would have brought up this: http://stackoverflow.com/questions/1289061/best-way-to-use-php-to-encrypt-and-decrypt – Thorsten Dittmar Mar 22 '12 at 12:46

juergen d, that is a valid point, but perhaps his vocabulary doesn't yet include the word hash?=) – Shaun Mason Mar 22 '12 at 12:46

@adesh: Well, if you create a hash in PHP and compare it to the hash in the database, then this is perfect. Just to get you on the way: When adding a new user to the database, store the user name and a hash of the password. Then, when the user logs in, search for an entry in the database which matches the entered user name and the hash of the password that the user has entered. That way you don't need to store any passwords at all in your database. – Thorsten Dittmar Mar 22 '12 at 12:47
