How to Manually Encode a Password
How to Manually Encode a Password¶
For historical reasons, Symfony uses the term “password encoding” when it should really refer to “password hashing”. The “encoders” are in fact cryptographic hash functions.
If, for example, you’re storing users in the database, you’ll need to encode the users’ passwords before inserting them. No matter what algorithm you configure for your user object, the hashed password can always be determined in the following way from a controller:
// whatever *your* User object is $user = new AppBundle\Entity\User(); $plainPassword = 'ryanpass'; $encoder = $this->container->get('security.password_encoder'); $encoded = $encoder->encodePassword($user, $plainPassword); $user->setPassword($encoded);
In order for this to work, just make sure that you have the encoder for your
user class (e.g.
AppBundle\Entity\User) configured under the
$encoder object also has an
isPasswordValid method, which takes
User object as the first argument and the plain password to check
as the second argument.
When you allow a user to submit a plaintext password (e.g. registration form, change password form), you must have validation that guarantees that the password is 4096 characters or fewer. Read more details in How to implement a simple Registration Form.
