Bcrypt (PHPPass) for CodeIgniter

Adaption of PHPPass (0.3) for use as a CodeIgniter Bcrypt library.

Allowed for the use of a separate config file, adjusted for some CodeIgniter configurability, added the scope of functions, changed hashing and checking functions to meet CodeIgniter standards for function names.

Installation

Place Bcrypt.php in your application/libraries folder.
Place bcrypt.php in your application/config folder.
Adjust options in the config file as neccessary.

Usage

First, load the Bcrypt library or autoload it in config/autoload.php.

$this->load->library('bcrypt');

Hashing

To hash a password, simply pass the string to hash_password().

$password = 'hunter2';
$hash = $this->bcrypt->hash_password($password);

The function will return the hashed password or * on error.

Checking

To check a hash password, simply pass the string and stored password to check_password().

$password = 'hunter2';

if ($this->bcrypt->check_password($password, $stored_hash))
{
	// Password does match stored password.
}
else
{
	// Password does not match stored password.
}

The function will return TRUE or FALSE dependant on success.

//For the model

function getUserByLogin($login, $password) {
$this->db->where('login',$login); $result = $this->getUsers($password);

if (!empty($result)) {
    return $result;
} else {
    return null;
}

}

function getUsers($password) { $query = $this->db->get('users');

if ($query->num_rows() > 0) {

    $result = $query->row_array();

    if ($this->bcrypt->check_password($password, $result['password'])) {
        //We're good
        return $result;
    } else {
        //Wrong password
        return array();
    }

} else {
    return array();
}
