How to encrypt a password field using BCRYPT using DataTables Editor in PHP?

sondhi

In one of my PHP based application, I am using DataTables Editor for CRUD functionality. Everything is OK until when I am trying to register a user. I want to use a custom hashing using PHP PASSWORD_BCRYPT rather than the DataTables default one.

But the problem is I can't figure out where I need to do that and how to do that!

Here is the function that I want to use in DataTables Editor for password hashing.

function encryption($password)
{
        $data = $password;
        $hash = "";
        if (version_compare(PHP_VERSION, '7.0', '>=')) {
            $hash = password_hash($data, PASSWORD_BCRYPT);
        } else {
            $options = [
                'cost' => 10,
                'salt' => mcrypt_create_iv(22, MCRYPT_DEV_URANDOM),
            ];
            $hash = password_hash($data, PASSWORD_BCRYPT, $options); //options is deprecated from PHP 7.0
        }

        return $hash;
}

Can anyone help me?

Use a custom setFormatter that will execute your encryption function and return the hash which will then be written to the database.

How can I write a custom setFormatter? Can you please provide any idea?

Here is something from my own coding. A password and a repeat password with validation plus get and set formatting.

Field::inst( 'user.password' )
    ->validator( function ( $val, $data, $opts ) {
        return validatorPassword($val);
    } )
    ->getFormatter( function ( $val, $data, $opts ) {
        return '';                   
    } )
    ->setFormatter( function($val, $data, $opts) {
        return password_hash($val, PASSWORD_DEFAULT, ['cost' => 14]);
    }),
Field::inst( 'user.password AS repeatPassword' )->set( false )
    ->validator( function ( $val, $data, $opts ) {
        return validatorPassword($val, $data['user']);
    } )
    ->getFormatter( function ( $val, $data, $opts ) {
        return '';                   
    } ),

The documentation shows a getFormatter code example and also notes that the setFormatter is basically the same.
