Laravel How the password is stored
Laravel makes secure password storage easy with its built-in hashing and salting features. Learn how to keep your user passwords safe with an example.
Password Storage in Laravel
Laravel uses the bcrypt
hashing algorithm to store passwords. This algorithm is designed to be slow and expensive in terms of computing resources. The purpose is to make it difficult for hackers to guess the passwords. In Laravel, the make:auth
command creates a migration that contains a users
table with a password
column. The password
column is a VARCHAR
with a length of 60
characters. The bcrypt
algorithm is used to hash the passwords before storing them in the password
column.
Below is an example of how a password is stored in the password
column using the bcrypt
algorithm:
$password = 'my secret password';
$hashedPassword = bcrypt($password);
echo $hashedPassword;
// Output: $2y$10$a/Q2Ew.GKfZG6HN/iitd/eVfzFm/K6/yM2F2QcO1Fjx.OoZPjXyXu
As you can see, the generated hash is significantly longer than the original password. This is a security measure so that if the database is compromised, the hacker will not be able to easily guess the original password. Also, since the bcrypt
algorithm is designed to be slow, it makes it difficult for hackers to guess the passwords even if they have the hashed version of the passwords.
Laravel also provides a Hash
facade which can be used to hash and verify passwords. The make:auth
command also creates a RegisterController
which uses the Hash
facade to hash the passwords before storing them in the database. The Hash
facade also provides methods to verify passwords, which is used when logging in to an application.
In summary, Laravel uses the bcrypt
algorithm to store passwords in the database. The generated hash is significantly longer than the original password. The Hash
facade provides methods to hash and verify passwords. This ensures that passwords are stored securely in the database.
