MySqlConnection（.NET）を使用してMySqlサーバーへのSSL接続が特定のクライアントから失敗する

Question

これはSSLに関する質問です。ソケットトレースは以下のとおりです。以前はMySqlを使用していました。

using (MySqlConnection con = new MySqlConnection(@"server=xxx.yyy.zzz.uuu;database=whopper;user=Username;password=Secret;Certificate Store Location=CurrentUser;Pooling=false;SSL Mode=Required;Certificate Thumbprint=NNNN;Keepalive=60")) { 
    con.Open(); 
} 

：とにかく、私たちはそうと、MySqlConnectionに（両方の.NET 2.0 & 4.0、バージョンは関係ありません）を使用して（クライアント.PFX証明書を使用して）SSL上のMySQLサーバに接続しようとしています証明書がパーソナルストアにインストールされていて、この全部がで動作します。マシンです。他の人には適用されません。 StackTrace：

、私はMySqlConnectionに最新のSRCをダウンロードしたので、私はAuthenticateAsClientへの呼び出しまで、あらゆるものに従うことができ、これをデバッグする - MySqlConnectionには、SSL接続をセットアップするために、.NETフレームワークを呼び出します。次の私はApp.configファイルに次を追加しました（ソケットトレースを取得することと、調査を継続する）：

（私は上記のファイルの証明書の部分を切り捨てました）。とにかく私の推測では、いくつかのマシンで受け取るエラーは、SSLハンドシェイクで選択されている暗号アルゴリズムに根ざしているということです。しかし、それは本当に暗い（？）のパンチで、私はこの瞬間に私の髪を裂いています。 SSLハンドシェイクは、一部のマシンでは失敗するようです。

私はWireSharkにいて、数時間頭を叩きましたが、上記の16進数をSSLに与える方法はまだ分かりません解剖学者）。または誰でも直接違いを見つけることができます/ 2番で失敗したものは、大いに役立ちます！

Answer 1

TLSプロトコルを解剖しているときに解決策を見つけました。上記の例で動作しないクライアントは、ハンドシェイク中にクライアント証明書を送信していることがわかります。そのクライアントはで作業しますはしません。とにかく暗号化が確立されている（私はTLSプロトコルを継続していない）、おそらく証明書交換/鍵交換がさらに行われる。

接続を有効にするには、接続文字列を変更してすべてのCertificate * =キーを削除するだけでした。特に、「証明書ストアの場所= CurrentUser」。 MySQLのSSLたconnectionStringを働くことである私の現在：

また

server=xxx.yyy.zzz.uuu;database=whopper;user=Username;password=Secret;Pooling=false;SSL Mode=Required;Keepalive=60 

、サイドノートとして、通信を解剖しながら、私はTamosのCommViewは、VPN通信にしばらく解剖&を傍受にWireSharkのより良い仕事をしていることが分かりました。おそらくWinPCapsがWindows 7 x64でVPNパケットを解読できないことが原因です。また、CommViewのTLSディセクタは、私がハンドシェイクの問題を見つけるのを本当に助けたものです。

また、第2の副言として。 WindowsのすべてのSSL/TLS通信は、schannel.dllというDLLによって処理されます。そのDLLのシステムイベントログへの完全なログオンは、値7のDWORD HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ SecurityProviders \ SCHANNEL \ EventLoggingを作成することで有効にできます。詳細はhttp://support.microsoft.com/kb/260729を参照してください。

これを機能させるにはものを取り除く。
