OpenSSL：サードパーティの証明書をチェックするためのOCSPサーバーの設定方法
CMTSデバイスの証明書失効機能をテストしています。これには、OCSPレスポンダをセットアップする必要があります。テストにのみ使用されるため、OpenSSLによって提供される最小限の実装で十分であると思います。
ケーブルモデムから証明書を抽出し、それを自分のPCにコピーして、PEM形式に変換しました。それをOpenSSL OCSPデータベースに登録し、サーバーを起動します。
これらの手順はすべて完了しましたが、クライアント要求を実行すると、サーバーは常に「不明」で応答します。私の証明書の存在を完全に認識していないようです。
誰かが私のコードを見て喜んでいただければ幸いです。便宜上、CAのセットアップからサーバーの起動まで、使用されたすべてのコマンドの順次リストで構成される単一のスクリプトを作成しました。 http://code.google.com/p/stacked-crooked/ source/browse/trunk/Misc/OpenSSL/AllCommands.sh
カスタム構成ファイルと私がテストしている証明書も見つけることができます： http://code.google.com/p/stacked-crooked/source/browse/trunk/Misc/OpenSSL/
どんな助けでも大歓迎です。
ご興味のある方のために：これが私の解決策です。
最初にOpenSSLのOCSPレスポンダーを捨てました。自己署名CAで作成されていない証明書には使用できません。
次に、OpenCAライブラリを使用して、OSCP要求からOCSP応答を作成できるコマンドラインユーティリティを作成しました。完全にファイルベースで機能します。DER形式のOSCP要求を入力ファイルとして実行し、DER形式のOCSP応答ファイルを出力します。
コマンドラインユーティリティの2番目の引数は、失効ステータスです。有効、失効、または不明です。応答ファイルの証明書ステータスは、渡された引数と同じになります。コードはこれに基づいています sampleこの投稿 の The Rook によって私に指摘されました。
最後のステップは、コマンドラインユーティリティを基に構築するHTTPサーバーを作成することでした。 RubyのMerbフレームワークを使用しました。気の利いた機能は、失効ステータスをHTTP URLとして要求できることです（例： http://127.0.0.1:5000/good ）。
