Java7拒绝信任存储中的证书

我有一个奇怪的问题 - 供应商将TLS SSLv3与自签名客户端和服务器证书一起使用。 这对于Java1.5和Java1.6来说并不是问题 - 只需将客户端证书和私钥导入密钥库并将服务器公共证书导入到信任库。 一切正常。 但是，对于Java7，即使使用相同的信任库，服务器证书也不可信。 我尝试过使用Java7（1.7.03,04和05，x86和x64版本）的Windows和Red Hat，但都没有成功。

我从零开始重新创建密钥库/信任库，它们只包含这些证书。 已经设置了相应的系统属性（javax.net.ssl.keyStore，javax.net.ssl.trustStore），关键方面是完全相同的代码和配置在JDK5 / 6中完美运行。

我无所适从 - 我找不到任何其他检查的参考，但我会认为证书位于信任库中的事实应该表示它是可信的，无论是否自签名。

任何帮助赞赏。 广告

实际上，我遇到了一个类似的问题，Tomcat应用程序在使用Java 1.6时信任truststore中的ca证书，并用java 1.7拒绝它。 将keyUsage添加到我的ca证书后，它可以工作（在阅读错误报告后，JDK-7018897：CertPath验证无法处理具有错误KeyUsage的自签名证书）。

我所做的（Ubuntu 12.04 x64）：

openssl x509 -in oldca.pem -clrext -signkey oldca.key -extfile /etc/ssl/openssl.cnf -extensions v3_ca -out newca.pem

在处理JDK 1.7时我也遇到过这种情况。 如果使用-x509选项调用req命令，最好取消注释v3_ca部分中的keyUsage行， 然后再次生成CA（请参阅http://wwwneu.secit.at/web/documentation/openssl/openssl_cnf.html）

openssl req -new -x509 -days 3650 -keyout ca.key -out ca.crt -config openssl.cnf -extensions v3_ca -batch

如果您使用生成的CA证书签署其他证书，请确保您也取消注释该项目basicConstraints = CA：true并将值设置为true
