问题描述

我正在尝试从通过Internet通信的Java客户端/服务器应用程序保护连接。我的想法是使用带有自签名证书和客户端身份验证的SSL套接字。我做了以下事情：

I'm trying to secure a connection from a Java Client/Server application that communicates over the Internet. My idea was to use SSL sockets with self-signed certificates and client authentication. I did the following:


  • 服务器：包含新的自签名证书的密钥库。 keytool -genkey -kelalg RSA ...

  • 客户端：包含新自签名证书的密钥库。 keytool -genkey -kelalg RSA ...

  • 服务器：包含导出的客户端证书的Truststore（来自上面的项目符号）。 keytool -export 导出客户端证书和 keytool -import -v -trustcacerts 将其导入服务器的信任库

  • 客户端：包含导出的服务器证书的Truststore（从第一个项目符号点开始）。 keytool -export 导出服务器证书和 keytool -import -v -trustcacerts 将其导入客户端的信任库

  • Server: Keystore containing new self-signed certificate. keytool -genkey -kelalg RSA ...
  • Client: Keystore containing new self-signed certificate. keytool -genkey -kelalg RSA ...
  • Server: Truststore containing exported client certificate (from bullet point above). keytool -export to export client certificate and keytool -import -v -trustcacerts to import it into the server's truststore
  • Client: Truststore containing exported server certificate (from first bullet point). keytool -export to export server certificate and keytool -import -v -trustcacerts to import it into the client's truststore

Trust-和keystores正确连接到服务器/客户端。我可以看到正在加载的证书（SSL调试信息）。但整件事情都行不通。在SSL握手期间，我收到以下错误（SSL调试信息）：

Trust- and keystores are attached correctly to the server/client. I can see the certificates being loaded (SSL debug information). But the whole thing doesn't work. During the SSL handshake, I get the following error (SSL debug information):

main, WRITE: TLSv1 Handshake, length = 897
main, READ: TLSv1 Handshake, length = 141
*** Certificate chain
***
main, SEND TLSv1 ALERT:  fatal, description = bad_certificate
main, WRITE: TLSv1 Alert, length = 2
main, called closeSocket()
main, handling exception: javax.net.ssl.SSLHandshakeException: null cert chain
main, IOException in getSession():  javax.net.ssl.SSLHandshakeException: null cert chain

    at sslsocket.Server.getClientDistinguishedName(Server.java:86)
    at sslsocket.Server.main(Server.java:37)

当我禁用客户端身份验证时，它可以正常运行。

When I disable client side authentication, it works flawlessly.

我真的很感激一些帮助。非常感谢！

I'd really appreciate some help. Thank you very much!

推荐答案

第一个SSL跟踪似乎是第二个跟踪的一部分，显示在服务器上。请确认。

The first SSL trace appears to be part of the second one, displayed at the server. Please confirm.

第二条跟踪显示服务器要求签署由'CN = xxxxxx客户端签名的RSA或DSS证书，OU =通信，O = xxxxxx，L = Zuerich，ST = ZH，C = CH'，客户端通过发送空证书链来回复。这只能意味着客户端的密钥库中没有这样的证书，或者客户端没有使用正确的密钥库。

The second trace shows that the server asked for an RSA or DSS certificate signed by 'CN=xxxxxx Client, OU=communication, O=xxxxxx, L=Zuerich, ST=ZH, C=CH', and the client replied by sending an empty certificate chain. That can only mean either that the client's keystore doesn't have such a cert in it or that the client wasn't using the correct keystore.
