我的问题是通过软件更新在我的工作笔记本电脑上安装了一个云访问安全代理NetSkope。这正在改变证书链，在将整个链导入到cacerts密钥存储库后，我仍然无法通过java客户端连接到服务器。我禁用了NetSkope，并且能够成功连接。

I am working on a tutorial for REST web services at www.udemy.com (REST Java Web Services). The example in the tutorial said that in order to have SSL, we must have a folder called "trust_store" in my eclipse "client" project that should contain a "key store" file (we had a "client" project to call the service, and "service" project that contained the REST web service - 2 projects in the same eclipse workspace, one the client, the other the service). To keep things simple, they said to copy "keystore.jks" from the glassfish app server (glassfish\domains\domain1\config\keystore.jks) we are using and put it into this "trust_store" folder that they had me make in the client project. That seems to make sense: the self-signed certs in the server's key_store would correspond to the certs in the client trust_store. Now, doing this, I was getting the error that the original post mentions. I have googled this and read that the error is due to the "keystore.jks" file on the client not containing a trusted/signed certificate, that the certificate it finds is self-signed.

为了让事情更清楚，让我说一下我理解的“密钥库”。“Jks”包含自签名的certs，以及“cacerts. Jks”。“jks”文件中包含CA证书(由CA签名)。“密钥存储库。Jks是“密钥存储库”，cacerts是“cacerts”。Jks”是“信任商店”。正如一位名叫“布鲁诺”的评论者所说，“密钥库。Jks是本地的，cacerts是本地的。Jks”用于远程客户端。

So, I said to myself, hey, glassfish also has the "cacerts.jks" file, which is glassfish's trust_store file. cacerts.jsk is supposed to contain CA certificates. And apparently I need my trust_store folder to contain a key store file that has at least one CA certificate. So, I tried putting the "cacerts.jks" file in the "trust_store" folder I had made, on my client project, and changing the VM properties to point to "cacerts.jks" instead of "keystore.jks". That got rid of the error. I guess all it needed was a CA cert to work.

这对于生产来说可能并不理想，甚至对于开发来说也不理想。例如，您可以使用“keytool”命令将CA证书添加到“密钥存储库”中。Jks”文件在客户端。但无论如何，希望这至少能缩小可能导致错误的情况。

另外:我的方法似乎对客户端有用(服务器证书添加到客户端trust_store)，看起来上面解决原始帖子的注释对服务器有用(客户端证书添加到服务器trust_store)。欢呼。

Eclipse项目设置:

MyClientProject src 测验 JRE系统库 .．. trust_store ——cacerts.jks ——keystore.jks

MyClientProject.java文件片段:

static {
  // Setup the trustStore location and password
  System.setProperty("javax.net.ssl.trustStore","trust_store/cacerts.jks");
  // comment out below line
  System.setProperty("javax.net.ssl.trustStore","trust_store/keystore.jks");
  System.setProperty("javax.net.ssl.trustStorePassword", "changeit");
  //System.setProperty("javax.net.debug", "all");

  // for localhost testing only
  javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(new javax.net.ssl.HostnameVerifier() {
        public boolean verify(String hostname, javax.net.ssl.SSLSession sslSession) {
          return hostname.equals("localhost");
        }

  });
}

我的问题是通过软件更新在我的工作笔记本电脑上安装了一个云访问安全代理NetSkope。这正在改变证书链，在将整个链导入到cacerts密钥存储库后，我仍然无法通过java客户端连接到服务器。我禁用了NetSkope，并且能够成功连接。

我在我的windows 10笔记本电脑上创建了一个ubuntu，当我试图从https://github.com/yahoo/CMAK网站加载CMAK网站下载时遇到了问题。首先，它给出了致命的ssl错误。

openssl s_client -showcerts -servername github.com -connect github.com:443 </dev/null 2>/dev/null | sed -n -e '/BEGIN\ CERTIFICATE/,/END\ CERTIFICATE/ p'  > github-com.pem

并使用以下命令(确保您为ca-cert设置了正确的路径)

cat github-com.pem | sudo tee -a /etc/ssl/certs/ca-certificates.crt

然后使用以下语句(确保cert的路径正确):

git config --global http.sslCAinfo /etc/ssl/certs/ca-certificates.crt

然后我能够下载CMAK，但当我尝试。/sbt清洁语句时遇到了问题。它给出了一个pkix路径错误。原因是我的cacert文件中没有存储我的公司颁发证书。

我已经下载了公司证书(谷歌)，并根据本文将下载的证书添加到cacert文件中。使用sudo update-ca-certificates之前一次。/ sbt。这对我很管用。

注意:在执行以上步骤时，您可能需要在root和exit之间切换。

这就是我所做的。

我想在Java 10上开发应用程序，我有Eclipse IDE 2020-06。 证书导入解决方案对我不起作用。 因此，我安装了Java 11 JDK，切换到最新的Eclipse IDE(在Java 11上运行)，并通过在Maven POM下添加以下语句来确保源代码仍然可以根据Java 10编译:

    <maven.compiler.target>1.10</maven.compiler.target>
    <maven.compiler.source>1.10</maven.compiler.source>
    <maven.compiler.release>10</maven.compiler.release>

它就像一个魔法;没有错误。

在我的例子中，我遇到了这个问题，因为在我的tomcat进程中，特定的密钥存储库是使用的

-Djavax.net.ssl.trustStore=/pathtosomeselfsignedstore/truststore.jks

当我将证书导入JRE/lib/security的cacert时，没有反映更改。 然后执行以下命令，其中/tmp/cert1。Test包含目标服务器的证书

keytool -import -trustcacerts -keystore /pathtosomeselfsignedstore/truststore.jks -storepass password123 -noprompt -alias rapidssl-myserver -file /tmp/cert1.test

可以再次检查证书导入是否成功

keytool -list -v -keystore /pathtosomeselfsignedstore/truststore.jks

并查看是否在别名rapidssl-myserver中找到您的taget服务器
