我正在使用带有 HTTPS 和有效证书的 Jetty，但我不确定它是否正确，因为服务器日志中的密码套件似乎是 SSL_NULL_WITH_NULL_NULL。然而，客户端日志看起来不错。
长话短说:我附上了一个需要 Jetty-7.6.10 的 Java 示例和两个用于创建 keystore 和信任库的脚本。
JettyHttpsForStackOverflow 同时或单独运行客户端和服务器以去复杂化日志。
create-chains.sh 脚本创建 keystore 和信任库。 keystore 包含一个由临时 keystore 生成的根证书颁发机构结尾的链。它使用证书颁发机构和中间证书复制真实案例。
create-single-autosigned.sh 脚本也创建 keystore 和信任库，但使用自签名证书。
请注意，SSL_NULL_WITH_NULL_NULL 显示为具有两个证书链的服务器密码套件。
我觉得服务器域名没有问题。对于在域名与正确签名证书中的专有名称匹配的机器上运行的服务器，我遇到了同样的问题。 SSLLab 确认我的服务器上的 SSL 工作正常(B 级)，并且 Google Chrome 可以愉快地连接。
我觉得Jetty客户端没有问题。当我使用它时，它只是调用我正在设置的 SSLContextFactory 来创建一个 SSLSocket。令人惊讶的是，在 Jetty 客户端日志中，TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA 似乎是正在使用的密码套件。
在 Jetty 服务器日志中获取 SSL_NULL_WITH_NULL_NULL 是否正常？如果不是，如何正确处理？

最佳答案
事实证明，Jetty-7.6.10.v20130312 中的 SslConnection 记录不正确，而加密却按预期进行。
长话短说:在创建时，SslConnection 从 SSLEngine 中提取初始的 SSLSession 对象，并用它继续记录。初始 SSLSession 有一个 SSL_NULL_WITH_NULL_NULL 密码，这是正常的，因为 SSL 握手尚未发生。激活-Djavax.net.debug=all显示确实发生了握手，交互式调试显示SSLEngine升级为具有真实密码的SSLSession .问题只是 Jetty 的 SslConnection 仍然使用初始 SSLSession 对象进行记录。 (它还使用来自初始 SSLSession 的值来分配缓冲区，但这是另一个问题。)
修补 SslConnection 以使用 _engine.getSession() 进行日志记录会得到预期的结果。
结语:Jetty 9 完全重写了它的 SslConnection。
