相关疑难解决方法(0)

这些是我用于密码加密和密码验证的一些功能.想知道这是否是处理它的好方法.我正在使用codeigniter框架.

这是'加密'的功能:

function crypt_pass( $input ){
    $salt = substr(sha1(date('r')), rand(0, 17), 22);
    $cost = 10;
    $hash = '$2y$' . $cost . '$' . $salt;

    $pw_and_salt['pw'] = crypt($input, "$hash");
    $pw_and_salt['salt'] = $salt;

    return $pw_and_salt;
}

我将密码和盐存储在我的数据库中.这是登录功能:

function login(){

    $this->db->select('salt');
    $salt = $this->db->get_where('users', array('username' => $this->input->post('username') ) )->row();



    $where = array(
        'username' => $this->input->post('username'),
        'password' => crypt( $this->input->post('password'), '$2y$10$' . $salt->salt),
    );


    $user = $this->db->get_where('users', $where)->first_row();

    if (!$user) {
        return FALSE;
    }else{
        if(!empty($user->activation)){

            return 2;

        }else if($user && empty($user->activation)){
            $this->session->set_userdata('id',$user->id);
            $this->session->set_userdata('username',$user->username);
            $this->session->set_userdata('first_name',$user->first_name); …
