Working with Passwords

Most developers know that passwords cannot be stored in plain text, but many developers believe it's still safe to hash passwords using md5 or sha1. There was a time when using the aforementioned hashing algorithms was sufficient, but modern hardware makes it possible to reverse such hashes and even stronger ones very quickly using brute force attacks.

Authorization

Authorization is the process of verifying that a user has enough permission to do something. Yii provides two authorization methods: Access Control Filter (ACF) and Role-Based Access Control (RBAC).
