if you want to use md5 encryptioon you can do it in your php script

$pass = $_GET['pass'];

$newPass = md5($pass)

and then insert it into the database that way, however MD5 is a one way encryption method and is near on impossible to decrypt without difficulty

use MD5    query  INSERT INTO ptb users  id  user id  first name  last name  email   VALUES  NULL    NULL       firstname         lastname         email     MD5     password           but MD5 is insecure  Use SHA2    Encryption and Compression Functions SQLFiddle Demo

Don t use MD5 as it is insecure   I would recommend using SHA or bcrypt with a salt   SHA256     password       http   en wikipedia org wiki Salt  cryptography

Darren Davies is partially correct in saying that you should use a salt - there are several issues with his claim that MD5 is insecure   You ve said that you have to insert the password using an Md5 hash  but that doesn t really tell us why  Is it because that s the format used when validatinb the password  Do you have control over the code which validates the password   The thing about using a salt is that it avoids the problem where 2 users have the same password - they ll also have the same hash - not a desirable outcome  By using a diferent salt for each password then this does not arise  with very large volumes of data there is still a risk of collisions arising from 2 different passwords - but we ll ignore that for now    So you can aither generate a random value for the salt and store that in the record too  or you could use some of the data you already hold - such as the username    query  INSERT INTO ptb users  id          user id          first name          last name          email           VALUES  NULL            NULL               firstname                 lastname                 email             MD5    user id  password                    I am assuming that you ve properly escaped all those strings earlier in your code

You can use MD5   in mysql or md5   in php  To use salt add it to password before running md5  f e     salt   my string    hash   md5  salt    password     It s better to use different salt for every password  For this you have to save your salt in db  and also hash   While authentication user will send his login and pass  You will find his hash and salt in db and find out   if   hash    md5  salt     POST  password
