NetCommons3のパスワード暗号化方法

Posted at

下記コードは暗号化再現コード。実際にはCakePHP2の Security::hash() を使ってるのでこのとおりじゃないですが…

// $salt app/Config/application.ymlにあるSecurity.salt app/Config/core.phpにあるSecurity.saltじゃないので注意。 
// $password 入力したパスワード
$encrypt = hash('sha512', $salt . $password);

このように app/Config/application.yml に記述してある salt を使うのでこのファイルを上書き等で紛失すると、一切ログインできなくなります。

開発環境等でMySQLのクエリでパスワードをまとめて更新するなら下記クエリで。

UPDATE users SET `password`=sha2('{{Salt}}{{Password}}', 512);
