Mar*_*rco 7 java authentication ssl nginx sni
I'm having a hard time connecting to a service with client authentication. The service ("SecureService") is on AWS. The clients are on a Linux VM on my Mac. Nginx on SecureService enforces Client Authentication on the resource I'm accessing on port 443. I can get a successful response connecting from the same VM to the same SecureService, using a proof of concept Java standalone application (openjdk 1.8.0_60) or other clients (wget, openssl), but not from the same Java code hosted on Websphere AS (admittedly relying on older libraries and IBM J9 VM, build 2.6, JRE 1.6.0). When remapping the SecureService hostname to 127.0.0.1 in /etc/hosts, though, that same java code on Websphere AS connects successfully to a local openSSL server requiring client authentication from the same Certification Authority. The response from SecureServer in the failing connection reports "400 No required SSL certificate was sent"... "400 Bad Request", but tcpdump packet captures show it's NOT sending a Certificate Request, whereas it is in all the other cases. This is puzzling and leads me to think there is something in the ClientHello message that the server doesn't like, though ClientHello messages in successful and failing connections are very similar.
一个非常奇怪的细节也是tcpdump从未在失败的通信中捕获从我的客户端到服务器的第一个TCP SYN数据包,而它捕获其余的(来自服务器的SYN + ACK,然后来自客户端的ACK)和所有数据包(所有其他通信上的SYN,SYN + ACK,ACK).
所有通信都在其所有部分中使用TLSv1.2.

有谁知道会出现什么问题？目前,我没有管理权限甚至帐户登录服务器.
已解决 - 我发现 Nginx 服务器需要在 Client Hello 中指定“server_name”扩展名。事实上，以下 openssl 命令会提示服务器发出证书请求...
/usr/local/Cellar/openssl/1.0.2e/bin/openssl s_client -cert client_identity.crt -key client_identity.key -connect SecureServerHostName:443 -debug <post_request.txt -tls1_2 -servername SecureServerHostName
...而省略“-servername”选项则不会。
我将如何强制 WebsphereAS 添加该扩展是另一双鞋。也许升级 Java 版本会有所帮助，因为可以更新 TLS 协议的实现。
更新：是的，将 IBM JDK 从 1.6 升级到 1.7.1 有效，生成带有服务器名称指示的客户端 Hello 消息，如此处所述（默认情况下 Java SE 7 启用服务器名称指示 (SNI)。）。
