セキュリティ

パスワードの保存方法 – 概要説明 –

ログイン機能を持つシステムではパスワードを平文(いわゆるそのまま)でデータベースに格納するのではなく、
パスワードからハッシュ関数により生成したハッシュを格納するのが当たり前のようです。
色々な方法があるようですが、現在(2017年1月)で推奨される方法を記載します。 “パスワードの保存方法 – 概要説明 –”

ソルト(salt)とは何かを調べてみた

パスワードをデータベースに格納する時にそのままのパスワードを登録せず、salt(ソルト)を使用して登録しているのが当たり前のようです。
PHPのフレームワークLaravelやEC Cubeもsaltが使用されています。
名前だけ知っていたので、勉強も兼ねて調べてみました。 “ソルト(salt)とは何かを調べてみた”
