JDK 8迁移到JDK 10时的解决方案

证书是非常不同的 JDK 10有80个，而JDK 8有151个 JDK 10最近添加了certs https://dzone.com/articles/openjdk-10-now-includes-root-ca-certificates http://openjdk.java.net/jeps/319

JDK 10

root@c339504909345:/opt/jdk-minimal/jre/lib/security #  keytool -cacerts -list
Enter keystore password:
Keystore type: JKS
Keystore provider: SUN

Your keystore contains 80 entries

JDK 8

root@c39596768075:/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/cacerts #  keytool -cacerts -list
Enter keystore password:
Keystore type: JKS
Keystore provider: SUN

Your keystore contains 151 entries

修复步骤

我删除了JDK 10证书，并将其替换为JDK 8 由于我正在构建Docker图像，我可以使用多阶段构建快速完成 我正在使用jlink作为/opt/jdk/bin/jlink \构建一个最小的JRE ——模块路径/ opt / jdk / jmods……

这里是不同的路径和命令的顺序…

# Java 8
COPY --from=marcellodesales-springboot-builder-jdk8 /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/cacerts /etc/ssl/certs/java/cacerts

# Java 10
RUN rm -f /opt/jdk-minimal/jre/lib/security/cacerts
RUN ln -s /etc/ssl/certs/java/cacerts /opt/jdk-minimal/jre/lib/security/cacerts

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");
        }

  });
}

我在试图从我的应用程序访问https url时遇到了这个错误，该应用程序正在使用自签名证书。 他们提供的是一个.cert文件，我不知道该把它放在哪里。我是这样解决的:

keytool的位置在JDK/bin文件夹下

方法1:将证书添加到默认的Java信任库- cacerts:

keytool -import -alias myCert -file C://certificate.cert -keystore C://Program Files//Java//jdk1.8.0_271//jre//lib//security//cacerts

密码:changeit

方法2:

创建信任存储:

keytool -import -alias myCert -file C://certificate.cert -keystore myTrustStore

它会给你以下提示，可以填充为:

Enter keystore password:changeit
Re-enter new password:changeit
Trust this certificate?yes

这将在运行此命令的文件夹中创建一个myTrustStore文件。 将这个“mytrustStore”复制到一个方便的位置。

使用信任存储:

当你运行你的应用程序/服务器时，传递这些JVM参数:

-Djavax.net.ssl.trustStore=C://myTrustStore -Djavax.net.ssl.trustStorePassword=changeit

在我的情况下，我得到错误连接到AWS Gov Postgres RDS。GOV RDS CA证书有一个单独的链接- https://s3.us-gov-west-1.amazonaws.com/rds-downloads/rds-combined-ca-us-gov-bundle.pem

将此pem certs添加到java的cacerts中。您可以使用下面的脚本。

——WINDOWDS步骤

使用VSCODE编辑器，安装openssl, keytool插件 在C:/rds-ca目录下创建目录 将“cacerts”文件和下面的脚本文件-“addCerts.sh”在目录“rd-ca” 运行vscode: 4.1 CD /c/rds-ca/ . 4.2。/ addCerts.sh 拷贝cacerts到${JAVA_HOME}/jre/lib/security目录下

脚本代码:

#!/usr/bin/env sh

OLDDIR="$PWD"

CACERTS_FILE=cacerts

cd /c/rds-ca

echo "Downloading RDS certificates..."

curl  https://s3.us-gov-west-1.amazonaws.com/rds-downloads/rds-combined-ca-us-gov-bundle.pem > rds-combined-ca-bundle.pem

csplit -sk rds-combined-ca-bundle.pem "/-BEGIN CERTIFICATE-/" "{$(grep -c 'BEGIN CERTIFICATE' rds-combined-ca-bundle.pem | awk '{print $1 - 2}')}"

for CERT in xx*; do
    # extract a human-readable alias from the cert
    ALIAS=$(openssl x509 -noout -text -in $CERT |
                   perl -ne 'next unless /Subject:/; s/.*CN=//; print')
    echo "importing $ALIAS"
    
    keytool -import \
            -keystore  $CACERTS_FILE \
            -storepass changeit -noprompt \
            -alias "$ALIAS" -file $CERT
done

cd "$OLDDIR"
echo "$NEWDIR"

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。

I had the same problem with sbt. It tried to fetch dependencies from repo1.maven.org over ssl but said it was "unable to find valid certification path to requested target url". so I followed this post and still failed to verify a connection. So I read about it and found that the root cert is not enough, as was suggested by the post,so - the thing that worked for me was importing the intermediate CA certificates into the keystore. I actually added all the certificates in the chain and it worked like a charm.
