I am using vBulletin and the login uses this to cross-refer to the database.

md5(md5($pass).$salt)

How do i make a PHP script such that every password input will automatically be hashed and salted as well so that it is able to authenticate with the vBulletin database ?

回答1:

Because hashing is not encrypting, hashes can't be reversed.

If you want to be able to reverse passwords, you have to use an encryption function.

How to reverse hashed and salted password ?

Hashing is a one-way process. i.e. If you pass a string you get a hash which cannot be reversed., It can be used for comparison purposes.

Some of the hashing algorithms are md5()[not considered secure] , sha-1, sha-256

Best Hashing as of now...

Make use of crypt() coupled with some strong salt. If you have PHP 5.5 , then you can very well make use of password_hash()

Just use the code you posted. Get the form data and wrap it in the appropriate md5() function.
