使用Zend Framework保存密码

Question

我已经创建了一个带有密码字段的表单，用于在网站上注册。

new Zend_Form_Element_Password('password', array(
    'required' => true,
    'label' => $this->getView()->translate('createprofile_password'),
    'filters' => array('StringTrim'),
    'validators' => array(
        new Zend_Validate_StringLength(array('min' => 6, 'max' => 20, 'encoding' => 'utf-8')),
    ),
    'class' => "validate['required','length[6,20]']",
)),

如何将其保存到数据库中？我试过这样的方法，但不起作用。密码未加密。

$profile = new Profile();
$entry = $profile->createEntry(array(
    'firstname' => $requestPost['firstname'],
    'lastname' => $requestPost['lastname'],
    'email' => $requestPost['email'],
    'password' => $requestPost['password'],
    'published' => 1,
));
$profileId = $entry->save();

Answer 1

这是一个简单的示例：

$profile = new Profile();
$entry = $profile->createEntry(array(
    'firstname' => $requestPost['firstname'],
    'lastname' => $requestPost['lastname'],
    'email' => $requestPost['email'],
     //hash password using sha1 and a salt (returns 40 character string) . 
     //Save the salt reference somewhere so you can rebuilt the string to compare hashes for authentication.
     //a salt is arbitrary data prepended or appended to the data being hashed
    'password' => sha1($salt . $requestPost['password']),
    'published' => 1,
));
$profileId = $entry->save();

要在以后对密码进行身份验证，请重新构建并散列字符串：

//both hashes should match exactly
if (sha1($salt . $inputPassword) === $password)//$password form data store

散列通常用于密码，因为它在资源上更容易使用，并且除了创建密码的人之外，没有人可以知道它。没有合理的方法来撤消加了盐的哈希。您所知道的就是输入的散列password+salt是否与保存的散列password+salt相同。
