Create a utility function to hash a password coming from the user.

And another utility to verify if a received password matches the hash stored.

And another one to authenticate and return a user.

# HTTP Basic 認証 { #http-basic-auth }

最もシンプルなケースでは、HTTP Basic 認証を利用できます。

HTTP Basic 認証では、アプリケーションはユーザー名とパスワードを含むヘッダーを期待します。

それを受け取れない場合、HTTP 401 "Unauthorized" エラーを返します。

そして、値が `Basic` のヘッダー `WWW-Authenticate` を、任意の `realm` パラメータとともに返します。

これにより、ブラウザは組み込みのユーザー名とパスワード入力プロンプトを表示します。

その後、そのユーザー名とパスワードを入力すると、ブラウザはそれらをヘッダーに自動的に付与して送信します。
