获取 javax.net.ssl.SSLHandshakeException:Android 5.0.2 中的连接被对等方关闭

Getting javax.net.ssl.SSLHandshakeException: Connection closed by peer in Android 5.0.2(获取 javax.net.ssl.SSLHandshakeException:Android 5.0.2 中的连接被对等方关闭)

问题描述

首先，我已经上网搜索，调试了3天.

First, I've already searched the internet and have been debugging for 3 days.

这是确切的错误，

出于保密原因，我无法发布代码.StackTrace 给出的异常不是由异常引起的，所以我无法真正诊断问题.

这里有一些我可以分享的信息.

Due to confidentiality reasons, I can't post the codes. There's no caused by exception given by the StackTrace so i can't really diagnose the problem.

Here are some information I can share.

• 请求正在发送到 https://[IP_address]:443/
• 我正在向特殊硬件(例如控制箱)发送请求.我只能通过 POST 请求写入和检索数据.
• 我在 CustomTrustManager 的 checkServerTrusted 方法中收到的证书链有一个 CN，它不是 IP 地址也不是 DNS，更像是一个词(即 CN=commonname).
• 我的 HostNameVerifier 暂时是 ALLOW_ALL_HOSTNAME_VERIFIER(我认为这可以解决第三个信息的问题?).
• 我正在使用 SSLContext.getInstance("TLS")，我的协议是 TLSv1、TLSv1.1 和 TLSv1.2.
• 所使用的证书是自签名的.
• 在 checkServerTrusted 方法中，X509Certificate 链始终受信任管理器信任(我创建了一个始终信任证书的 trustManager).

我们将不胜感激.

Any inputs will be appreciated.

推荐答案

我的问题的答案是我注释了将生成的私钥添加到我的密钥库的代码，因此 SSL HandShake 在客户端身份验证期间失败.

The answer to my problem was that I commented the code for adding my generated private key to my key store so the SSL HandShake fails during client authentication.

我希望这个答案可以帮助别人.

I hope this answer can help somebody.
