Java:SSL客户端身份验证和自签名证书

Question

我正在尝试保护通过Internet进行通信的Java客户机/服务器应用程序的连接。我的想法是使用带有自签名证书和客户端身份验证的SSLsocket。我做了以下工作：

• 服务器：包含新的自签名证书的密钥库keytool -genkey -kelalg RSA ...
• 客户端：包含新的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信任库（来自上面的要点）keytool -export导出客户端证书，并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信任库（从第一个要点开始）keytool -export导出服务器证书keytool -import -v -trustcacerts将其导入客户端的信任库

信任和密钥存储正确地连接到服务器/客户端。我可以看到正在加载的证书（SSL调试信息）。但这一切都不起作用。在SSL握手过程中，我收到以下错误（SSL调试信息）：

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
javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated
    at com.sun.net.ssl.internal.ssl.SSLSessionImpl.getPeerCertificateChain(Unknown Source)
    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，它可以完美地工作

我非常感谢你的帮助。多谢各位

第一个SSL跟踪似乎是服务器上显示的第二个SSL跟踪的一部分。请确认

第二个跟踪显示，服务器请求一个RSA或DSS证书，该证书由'CN=xxxxxx Client，OU=communication，O=xxxxxx，L=Zuerich，ST=ZH，C=CH'签名，客户端通过发送一个空证书链进行回复。这只能意味着客户机的密钥库中没有这样的证书，或者客户机没有使用正确的密钥库
