如何使用客户端证书/相互身份验证调用Web服务?

我正在使用vb .net构建一个Web服务客户端。 Web服务使用ssl,基本身份验证进行保护,还需要客户端证书。所以我在Visual Studio中创建了一个Web引用并提供了凭据:

Dim cred As New System.Net.NetworkCredential("usr", "passwd")
Dim proxy As New SimpleFromLocal.simple
proxy.Credentials = cred

Console.WriteLine(proxy.helloWorld())

只要我关闭服务器端的相互身份验证,这就可以正常工作。 我添加了这样的客户端证书:

Dim cert As X509Certificate = X509Certificate.CreateFromCertFile(certFile)
proxy.ClientCertificates.Add(cert)

已加载证书,但Web服务调用失败。我可以发布异常,但它是德语,这本身就是一个问题。它基本上说:身份验证失败,因为远程站点关闭了连接。 我尝试在服务器端调试ssl握手,看起来好像没有传输客户端证书。

那我在这里错过了什么?是否需要在本地计算机上安装客户端证书?

最后!

question让我尝试使用X509Certificate2(请注意班级名称中的 2 )。我将它用于仅包含单个证书的PKCS#12密钥库。所以这就是我所做的:

创建密钥库文件

我使用了Java的keytool。创建自签名证书后,需要将其导出为所需格式:

keytool -importkeystore -srckeystore keystore.jks \
        -srcstoretype JKS \
        -destkeystore keystore.pfx \
        -deststoretype PKCS12

注意:将证书导出到文件并直接使用它不起作用。

将客户端证书添加到代理

Dim proxy As New SimpleFromLocal.simple
Dim cred As New NetworkCredential("usr", "passwd")
Dim cert As New X509Certificate2(certFile, "passwd")
proxy.Credentials = cred
proxy.ClientCertificates.Add(cert)

Console.WriteLine(proxy.helloWorld())

就是这样。无论出于何种原因,相同的设置都无法使用X509Certificate
