“PKIX路径构建失败”和“无法找到请求目标的有效证书路径”

问题描述 投票:301回答:26

我正在尝试使用twitter4j库为我的java项目发送推文。在我第一次运行时,我得到了关于证书sun.security.validator.ValidatorExceptionsun.security.provider.certpath.SunCertPathBuilderException的错误。然后我添加了twitter证书:

C:\Program Files\Java\jdk1.7.0_45\jre\lib\security>keytool -importcert -trustcacerts -file PathToCert -alias ca_alias -keystore "C:\Program Files\Java\jdk1.7.0_45\jre\lib\security\cacerts"

但没有成功。这是获得twitters的过程:

public static void main(String[] args) throws TwitterException {
    ConfigurationBuilder cb = new ConfigurationBuilder();
    cb.setDebugEnabled(true)
        .setOAuthConsumerKey("myConsumerKey")
        .setOAuthConsumerSecret("myConsumerSecret")
        .setOAuthAccessToken("myAccessToken")
        .setOAuthAccessTokenSecret("myAccessTokenSecret");

    TwitterFactory tf = new TwitterFactory(cb.build());
    Twitter twitter = tf.getInstance();

    try {
        Query query = new Query("iphone");
        QueryResult result;
        result = twitter.search(query);
        System.out.println("Total amount of tweets: " + result.getTweets().size());
        List<Status> tweets = result.getTweets();

        for (Status tweet : tweets) {
            System.out.println("@" + tweet.getUser().getScreenName() + " : " + tweet.getText());
        }
    } catch (TwitterException te) {
        te.printStackTrace();
        System.out.println("Failed to search tweets: " + te.getMessage());
    }

这是错误:

sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

  1. 转到firefox浏览器中的URL,单击HTTPS证书链(URL地址旁边)。点击"more info" > "security" > "show certificate" > "details" > "export.."。选择名称并选择文件类型example.cer。现在你有了keystore的文件,你必须将它添加到你的JVM
  2. 确定cacerts文件的位置,例如。 C:\Program Files (x86)\Java\jre1.6.0_22\lib\security\cacerts.
  3. 接下来,在命令行中将example.cer文件导入cacerts:

keytool -import -alias example -keystore C:\Program Files (x86)\Java\jre1.6.0_22\lib\security\cacerts -file example.cer

系统会要求您输入密码,默认为changeit

重新启动JVM / PC。

这不是Twitter特定的答案,但这是您搜索此错误时出现的问题。如果您的系统在连接到在Web浏览器中查看时似乎具有有效证书的网站时收到此错误,则可能表示该网站的证书链不完整。

有关问题的简短摘要:证书颁发机构不使用其根证书来签署任何旧证书。相反,它们(通常)签署也设置了证书颁发机构标志的中间证书(即允许签署证书)。然后,当您从CA购买证书时,他们会使用其中一个中间证书对您的CSR进行签名。

您的Java信任存储很可能只有根证书,而不是中间证书。

配置错误的网站可能只返回其签名的证书。问题:它是使用不在您的信任库中的中间证书签名的。浏览器将通过下载或使用缓存的中间证书来处理此问题;这最大化了网站兼容性。但是,像OpenSSL这样的Java和工具却不会。这将导致问题中的错误。

您可以使用Qualys SSL Test来验证这种怀疑。如果你针对网站运行它,它说

此服务器的证书链不完整。

然后证实了这一点。您还可以通过查看认证路径并查看文本Extra Download来查看此信息。

如何解决:服务器管理员需要配置Web服务器以返回中间证书。例如,对于Comodo来说,这就是.ca-bundle文件派上用场的地方。例如,在使用mod_ssl的Apache配置中,您将使用SSLCertificateChainFile配置设置。对于nginx,您需要连接中间证书和签名证书,并在SSL证书配置中使用它。您可以通过在线搜索“不完整的证书链”找到更多信息。

我们得出以上错误的原因是JDK与许多可信证书颁发机构(CA)证书捆绑在一个名为'cacerts'的文件中,但是这个文件并不知道我们的自签名证书。换句话说,cacerts文件没有导入我们的自签名证书,因此不会将其视为可信实体,因此它会产生上述错误。

How to fix the above error

要解决上述错误,我们只需将自签名证书导入cacerts文件即可。

首先,找到cacerts文件。我们需要找出JDK的位置。如果您通过IDE之类的IDE或IntelliJ Idea运行应用程序,请转到项目设置并找出JDK位置。例如,在Mac OS上,cacerts文件的典型位置将位于Window的机器上的此位置/ Library / Java / JavaVirtualMachines / {{JDK_version}} / Contents / Home / jre / lib / security中,它位于{{Installation_directory}下} / {{JDK_version}} / JRE / LIB /安全

找到cacerts文件后,现在我们需要将自签名证书导入此cacerts文件。如果您不知道如何正确生成自签名证书,请查看上一篇文章。

如果您没有证书文件(.crt)并且只有.jks文件,则可以使用以下命令生成.crt文件。如果您已经有.crt / .pem文件,则可以忽略以下命令

##从密钥库生成证书(.jks文件)####

keytool -export -keystore keystore.jks -alias selfsigned -file selfsigned.crt

上面的步骤将生成一个名为selfsigned.crt.Now的文件,将证书导入cacerts

Now add the certificate to JRE/lib/security/cacerts (trustore)
keytool -importcert -file selfsigned.crt -alias selfsigned -keystore {{cacerts path}}

例如

keytool -importcert -file selfsigned.nextgen.crt -alias selfsigned.nextgen -keystore /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre/lib/security/cacerts

这就是全部,重新启动您的应用程序,它应该工作正常。如果它仍然不起作用并获得SSL握手异常。这可能意味着您使用的是不同的域,然后在证书中注册。

添加cacerts不适合我。在启用带有标志-Djavax.net.debug=all的日志之后,就开始了解来自jssecacerts的java阅读。

导入jssecacerts终于工作了。

我试图通过他们的更新站点在Eclipse中安装Cucumber-Eclipse插件时遇到了这个问题。我收到了相同的SunCertPathBuilderException错误:

Unable to read repository at http://cucumber.io/cucumber-eclipse/update-site/content.xml.
    Unable to read repository at http://cucumber.io/cucumber-eclipse/update-site/content.xml.
    sun.security.validator.ValidatorException: PKIX path building failed: 
   sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

虽然其他一些答案对于这个问题的具体情况是恰当和有用的,但它们对我的问题无益和误导。

就我而言,问题是为其更新站点提供的URL是:

https://cucumber.io/cucumber-eclipse/update-site

但是,当通过浏览器导航到它时,它会重定向到(注意添加的“.github”):

http://cucumber.github.io/cucumber-eclipse/update-site/

所以解决方案是在eclipse中添加更新站点时简单地使用重定向版本的更新站点URL。

我遇到了同样的问题,并使用以下简单的步骤解决了这个问题:

1)从谷歌下载InstallCert.java

2)使用javac InstallCert.java编译它

3)使用带有主机名和https端口的java InstallCert.java运行InstallCert.java,并在请求输入时按“1”。它将“localhost”添加为可信密钥库,并生成名为“jssecacerts”的文件,如下所示:

java InstallCert localhost:443

4)将jssecacerts复制到$ JAVA_HOME / jre / lib / security文件夹中

我在ubuntu 15.10上遇到了同样的问题。请尝试在本地下载插件,例如https://github.com/lmenezes/elasticsearch-kopf/archive/master.zip并使用此命令安装:

sudo /usr/share/elasticsearch/bin/plugin install file:/home/dev/Downloads/elasticsearch-kopf-master.zip

路径可能因您的环境而异。

对我来说,证书错误突然出现,因为我在背景中运行小提琴手并且与证书混淆。它充当代理,如此接近并重启eclipse。

这是答案https://stackoverflow.com/a/36427118/1491414的补充。谢谢@MagGGG

  • 请确保您拥有管理员权限
  • 请使用双引号作为密钥库路径(-keystore C:\ Program Files(x86)\ Java \ jre1.6.0_22 \ lib \ security \ cacerts“),因为在Windows操作系统中,默认安装位置将是Program Files,您将获得由于程序文件之间的空间错误。

我用以下方法解决了这个问题 -

  1. 复制有连接问题的网址
  2. 转到Android Studio->设置 - > Http设置
  3. 在“测试连接”中,粘贴该网址并按“确定”
  4. 在Ok上单击,Android Studio将要求导入该URL的证书,导入它
  5. 而已。没有别的事情要做,我的问题就没了。也不需要重启工作室。

经过几个小时尝试构建证书文件以使我的Java 6安装与新的twitter证书一起使用后,我终于偶然发现了一个非常简单的解决方案,其中包含了其中一个留言板的评论。只需从Java 7安装中复制cacerts文件,并覆盖Java 6安装中的文件。可能最好先备份cacerts文件,但是你只需要复制新的文件和BOOM!它只是工作。

请注意,我实际上将Windows cacerts文件复制到Linux安装上,它运行得很好。

该文件位于新旧Java jdk安装中的jre/lib/security/cacerts中。

希望这可以拯救别人几个小时的恶化。

当您使用atlassian软件时遇到以上错误。 JIRA

2018-08-18 11:35:00,312 Caesium-1-4 WARN anonymous    Default Mail Handler [c.a.mail.incoming.mailfetcherservice] Default Mail Handler[10001]: javax.mail.MessagingException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target while connecting to host 'imap.xyz.pl' as user '[email protected]' via protocol 'imaps, caused by: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

您可以将证书添加到其可信密钥库(将missing_ca更改为正确的证书名称):

keytool -importcert -file missing_ca.crt -alias missing_ca -keystore /opt/atlassian/jira/jre/lib/security/cacerts

如果要求输入密码changeit并确认y

之后只需重启jira。

如果您的存储库URL也适用于HTTP并且安全性不是问题,您可以转到settings.xml(通常但不总是位于%USERPROFILE%/.m2中)并使用HTTP替换HTTPS以用于<repository><pluginRepository> URL。

例如,这个:

<repository>
    <snapshots>
        <enabled>false</enabled>
    </snapshots>
    <id>central</id>
    <name>libs-release</name>
    <url>https://<artifactory>/libs-release</url>
</repository>

应该替换为:

<repository>
    <snapshots>
        <enabled>false</enabled>
    </snapshots>
    <id>central</id>
    <name>libs-release</name>
    <url>https://<artifactory>/libs-release</url>
</repository>

通过arg -Djavax.net.ssl.trustStore=我使用自己的信任商店而不是JRE

无论信任库中的证书是什么,我都收到此错误。对我来说,问题是arg行传递的属性的排序。当我在-Djavax.net.ssl.trustStore=-Djavax.net.ssl.trustStorePassword= args之前放-Dspring.config.location=-jar时,我能够通过https成功调用我的休息呼叫。

如果您在java应用程序尝试与另一个应用程序/站点通信时在linux容器中看到此问题,那是因为证书已错误地导入负载均衡器。导入证书需要遵循一系列步骤,如果操作不正确,您将看到类似的问题

Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid 
certification path to requested target

一旦正确导入证书,就应该完成。无需修改任何JDK证书。

这是一个解决方案,但我的故事形式有这个问题:

我几乎死了尝试上面给出的所有解决方案(3天),没有任何对我有用。

我失去了所有希望。

我联系了我的安全团队,因为我是代理人,他们告诉他们最近更新了他们的安全策略。

我没有通知开发人员,因此严厉责骂他们。

后来他们发布了一个新的“cacerts”文件,其中包含所有证书。

我删除了%JAVA_HOME%/ jre / lib / security中存在的cacerts文件,它解决了我的问题。

因此,如果您遇到此问题,可能来自您的网络团队也是这样的。

目标:

  1. 使用https连接
  2. 验证SSL链
  3. 不要处理cacerts
  4. 在运行时添加证书
  5. 不要丢失cacerts的证书

怎么做:

  1. 定义自己的密钥库
  2. 将证书放入密钥库
  3. 使用我们的自定义类重新定义SSL默认上下文
  4. ???
  5. 利润

我的Keystore包装文件:

        }
    }

    public SSLSocketFactory getSocketFactory() {
        return socketFactory;
    }
}

此类作为单例生成,因为只允许一个defaultSSL上下文。那么,现在用法:

            CertificateManager certificateManager = new CertificateManager("C:\\myapplication\\mykeystore.jks", "changeit");
            String certificatePath = "C:\\myapplication\\public_key_for_your_ssl_service.crt";
            try {
                certificateManager.addCustomCertificate(certificatePath, "alias_for_public_key_for_your_ssl_service");
            } catch (Exception e) {
                log.error("Can't add custom certificate");
                e.printStackTrace();
            }
            CustomTrustManager.getInstance().register(certificateManager);

可能,它不适用于此设置,因为我将证书文件保存在资源文件夹中,所以我的路径不是绝对的。但一般来说,它完美地运作。

如果您的主机位于防火墙/代理后面,请在cmd中使用以下命令:

keytool -J-Dhttps.proxyHost=<proxy_hostname> -J-Dhttps.proxyPort=<proxy_port> -printcert -rfc -sslserver <remote_host_name:remote_ssl_port>

<proxy_hostname><proxy_port>替换为配置的HTTP代理服务器。将<remote_host_name:remote_ssl_port>替换为远程主机(基本上是url)和具有认证问题的端口之一。

获取打印的最后一个证书内容并将其复制(同时复制开始和结束证书)。将其粘贴到文本文件中,并为其指定.crt扩展名。现在使用java keytool命令将此证书导入cacerts,它应该可以工作。

keytool -importcert -file <filename>.crt -alias randomaliasname -keystore %JAVA_HOME%/jre/lib/security/cacerts -storepass changeit

下载cert文件,并使用证书文件更新密钥库,如下面的命令所示。

sudo keytool -importcert -alias“aws2”-file~ / Desktop / * aws.crt -keystore /Library/java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/jre/lib/security/cacerts

我偶然发现了这个需要花费数小时研究才能修复的问题,特别是使用自动生成的证书,这与官方证书不同,它们非常棘手,而Java并不那么喜欢它们。

请检查以下链接:Solve Problem with certificates in Java

基本上,您必须将证书从服务器添加到Java Home证书。

  1. 生成或获取证书并配置Tomcat以在Servers.xml中使用它
  2. 下载类InstallCert的Java源代码并在服务器运行时执行它,提供以下参数server[:port]。不需要密码,因为原始密码适用于Java证书(“changeit”)。
  3. 程序将连接到服务器,Java将抛出异常,它将分析服务器提供的证书,并允许您在执行程序的目录中创建jssecerts文件(如果从Eclipse执行,请确保配置Run -> Configurations的工作目录)。
  4. 手动将该文件复制到$JAVA_HOME/jre/lib/security

执行这些步骤后,与证书的连接将不再在Java中生成异常。

以下源代码很重要,它从(Sun)Oracle博客中消失,我发现它唯一的页面是在提供的链接上,因此我将其附在答案中以供参考。

我的UI方法:

  1. 下载http://www.keystore-explorer.org/
  2. 打开$ JAVA_HOME / jre / lib / security / cacerts
  3. 输入PW:更改它(可以在Mac上更改)
  4. 导入.crt文件

CMD线:

  1. keytool -importcert -file jetty.crt -alias jetty -keystore $ JAVA_HOME / jre / lib / security / cacerts
  2. 输入PW:更改它(可以在Mac上更改)

当我的系统上存在JDK和JRE 1.8.0_112时,情况略有不同。

我使用已知的命令将新CA证书导入[JDK_FOLDER]\jre\lib\security\cacerts

keytool -import -trustcacerts -keystore cacerts -alias <new_ca_alias> -file <path_to_ca_cert_file>

尽管如此,我仍然保持相同的PKIX路径构建失败错误。

我使用java -Djavax.net.debug=all ... > debug.log将调试信息添加到java CLI。在debug.log文件中,以trustStore开头的行是:实际指向[JRE_FOLDER]\lib\security\cacerts中的cacerts存储。

在我的情况下,解决方案是将JDK(添加了新CA)使用的cacerts文件复制到JRE使用的文件上并修复了问题。

1.检查证书

尝试在浏览器中加载目标URL并查看站点的证书(通常可以通过带有锁定符号的图标访问它。它位于浏览器地址栏的左侧或右侧)是否由于其他原因而过期或不受信任。

2.安装最新版本的JRE和JDK

新版本通常附带更新的可信证书集。

如果可能的话,卸载旧版本。这将使错误配置错误显而易见。

3.检查您的配置:

  • 检查JAVA_HOME环境变量指向的位置。
  • 检查用于运行程序的java版本。在IntelliJ检查中: 文件 - >项目结构... - >项目设置 - >项目 - >项目SDK: 文件 - >项目结构... - >平台设置 - > SDK

4.从新Java版本复制整个密钥库

如果您使用JDK以外的最新版本进行开发 - 尝试用最新安装的JRE替换%JAVA_HOME%/jre/lib/security/cacerts文件(首先制作备份副本),如@ jeremy-goodell在他的answer中建议的那样

5.将证书添加到密钥库

如果以上没有解决您的问题,请使用keytool将证书保存到Java的密钥库:

keytool -trustcacerts -keystore "%JAVA_HOME%jre\lib\security\cacerts" -storepass changeit -importcert -alias <alias_name> -file <path_to_crt_file>

带有证书的文件可以从@MagGGG在他的answer中建议的浏览器中获得。

注意1:您可能需要对链中的每个证书重复此操作,以获取您站点的证书。从根目录开始。

注2:<alias_name>在商店的钥匙中应该是唯一的,否则keytool会显示错误。

要获取商店中所有证书的列表,您可以运行:

keytool -list -trustcacerts -keystore "%JAVA_HOME%jre\lib\security\cacerts" -storepass changeit

如果出现问题,这将有助于您从商店中删除证书:

keytool -delete -alias <alias_name> -keystore "%JAVA_HOME%jre\lib\security\cacerts" -storepass changeit

我想为smtp.gmail.com导入证书

只有解决方案适用于我1.输入命令查看此证书

D:\ openssl \ bin \ openssl.exe s_client -connect smtp.gmail.com:465

  1. 将“----- BEGIN CERTIFICATE -----”和“----- END CERTIFICATE -----”之间的行复制并保存到文件gmail.cer中
  2. 跑 keytool -import -alias smtp.gmail.com -keystore“%JAVA_HOME%/ jre / lib / security / cacerts”-file C:\ Users \ Admin \ Desktop \ gmail.cer
  3. 输入密码chageit
  4. 单击“是”以导入证书
  5. 重启java

现在运行命令,你很高兴

问题背景:

当我尝试在我的项目中运行mvn clean install并通过Netbeans IDE clean和build选项时,我遇到了以下错误。此问题是由于我们通过NET beans IDE /通过命令提示符下载时无法使用证书,但能够通过浏览器下载文件。

错误:

Caused by: org.eclipse.aether.transfer.ArtifactTransferException: Could not transfer artifact com.java.project:product:jar:1.0.32 from/to repo-local (https://url/local-repo): sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target  

解析度:

1.下载相关网址的证书:

  • 通过“以管理员身份运行”启动IE(否则,我们将无法下载证书)
  • 在IE-> https://url/local-repo中输入网址(在我的情况下,这个网址有一个不受信任的certificateenter image description here。)
  • 单击证书错误 - >查看证书下载证书
  • 选择Details选项卡 - > copy to file - > next - >选择“DER编码二进制X.509(.CER)
  • 将证书保存在某个位置,例如:c:/user/sheldon/desktop/product.cer
  • 恭喜!您已成功下载该站点的证书

2.现在安装密钥库以解决问题。

  • 运行keytool命令将下载的密钥库附加到现有证书文件中。
  • 命令:在jdk(JAVA_HOME)的bin文件夹中的命令下面。

C:\ Program Files \ Java \ jdk1.8.0_141 \ jre \ bin> keytool -importcert -file“C:/user/sheldon/desktop/product.cer”-alias product -keystore“C:/ Program Files / Java / jdk1.8.0_141 / JRE / lib / security中/ cacerts中”。

  • 系统将提示您输入密码。输入密钥库密码:再次为“信任此证书?[否]:”输入“changeit”,输入“是”

示例命令行命令/输出:

keytool -importcert -file "C:/Users/sheldon/Desktop/product.cer" -alias product -keystore "C:/Program iles/Java/jdk1.8.0_141/jre/lib/security/cacerts"
Enter keystore password:
Trust this certificate? [no]:  yes
Certificate was added to keystore
  • 恭喜!现在你应该摆脱Netbeans IDE中的“PKIX路径构建失败:sun.security.provider.certpath.SunCertPathBuilderException”错误。
