Hi Friends ....
I encrypt user password by SHA('$Password') method but now i want to add "Forget Password Module" for which I need to decrypt it first before tell my user but I don't Know how to decrypt it.
Please help me........

not reversible...
you could allow the user to change the password though on forget password !

Your code didn't display properly because you used (php) not (code=php).

Most of the encryption methods used for passwords are not reversible because it makes them more secure. Even with access to the database, you can't determine what the actual password is (except maybe by brute force). The normal approach for a lost password is for you to replace the lost password with a temporary password that you give them (and force them to change on the first login) or, allow them to create a new password to replace the one that was lost.

I use aes_encrypt and aes_decrypt for mysql. You just need to figure out a way to securely use a key to encrypt and decrypt with.

What is this "aes-encrypt".
Plz tell me more about it....



create table user_info(
user_infopk int primary key auto_increment,
name varchar(100),
email text,
phone text);

#insert a record with phone and email encrypted
insert into user_info(name, email, phone) values(
aes_encrypt('jimbo@email.com', 'passphrase to use to decrypt up to 128 bits'),
aes_encrypt('999-999-9999', 'passphrase to use to decrypt up to 128 bits'));

#pull the data out decrypted
select name, trim(aes_decrypt(email, 'passphrase to use to decrypt up to 128 bits')) as email, trim(aes_decrypt(phone, 'passphrase to use to decrypt up to 128 bits')) as phone from user_info;

obviously you have to be creative with how you store the pass phrase so that nobody can get ahold of it.

If a user of your web application could retrieve his password over “retrieve password” section he could understand that you save the password directly so if your site been hacked (with recently examples) his password would be almost public.

The best way in my view is in the retrieve password section to let your user enter new password and send him / her confirmation mail for that change (keeping the request in a separate table). Of course password should saved in shadow / hash algorithms and also I believe that the best way is your own “mix” of existence ones.

Be aware that to have maximum efficiency the first shadow pass (the first hash of the password) should be done by JavaScript in the users browser, so that in no case the password be sent throw Internet. (You can complete the hashing in PHP combining knowing algorithms and your own)

I agree, you should always use an irreversible method when dealing with passwords.

if you are that worried about posted passwords, the standard is SSL.

In my opinion JS is not a good solution. Sending the password:


or the hash (sha1 in this example):


it's the same for the attacker, it's always plain text. The attacker can sniff the user submission, catch the hash and send it to gain the access, you don't have the password, ok, but you have the "key".

I agree with R0bb0b, ssl is the right way to manage this problem.
