RabbitMQ has inbuilt support for TLS. Develop a greater intuition for the proper use of cryptography. aes-256-ctr is arguably the best choice for cipher algorithm as of 2016. AES/GCM/NoPaddingの暗号化にOracleUcryptoプロバイダを使用すると、Solaris 11以降のリリースで予期しないIllegalBlockSizeExceptionがスローされる場合があります。 次の回避策を使用できます。. Note that symmetric encryption is not sufficient for most applications because it only provides secrecy but not authenticity. Therefore, customer interactions with AWS via modern web browsers or client applications which appropriately negotiate AES-GCM for TLS/SSL are not impacted by this issue. 誰もGCMモードで認証されたAESを簡単に提供する、Pythonライブラリまたはacライブラリのラッパーを知っていますか? PyCryptoはそれをサポートしておらず、PyOpenSSLがOpenSSLの対称暗号部分への直接アクセスをサポートしているようには見えません. the AWS Management Console, S3, CloudFront, and ELB, prefers and recommends AES-GCM TLS/SSL cipher suites. AES-GCM is authenticated cipher. encode('utf-8')).
