[Solved] Password Hash in PHP with Source Code

how to decrypt password_hash in php compares the integrity of your password submitted at login to the stored hash, eliminating the need to retain your actual password. Not all encryption algorithms are appropriate for modern business.

This is advantageous because the algorithm can evolve over time to become more powerful as needed without requiring you to update your code. Don’t worry about backwards compatibility: password hash() preserves the algorithm name in its hashes as well, allowing it to check hashes even if the algorithm is changed.

implement password hash in PHP, The password verify function takes your previously constructed hash, removes the salt, and hashes your value with the salt you have. password verify($value, $hash) is used because $value is the user’s password and $hash is required for the salt and the number of rounds from our previous hash.

A hashing function converts your password into a hash. The generated hash is compared to the hash stored in the database. If the the generated hash and the stored hash match, you’re granted access to the account. If the generated hash doesn’t match, you get a login error.

While the password should be encrypted during transmission, the password hash does not need to be encrypted at rest. Password hashing is cryptographically secure when done correctly. To get around the constraints of hash functions, this version would employ a salt.
