有些客户接受SSL证书;其他人拒绝它-Java 学习之路

某些HTTP客户端接受此证书，而其他HTTP客户端则不接受 . 什么可以有所作为？

为什么行为不同？

某些HTTP客户端接受此证书，而其他客户端则不接受 . 什么可以有所作为？

简短的回答：负载 balancer ，虚拟主机和SNI .

答案很长......首先，这是对证书的分析 . 我们需要做到这一点，以确保没有明显的错误 .

从下面的转储中，公共名称中有一个通配符DNS名称 . IETF和CA /浏览器论坛都不推荐在CN中放置DNS名称 . “友好名称”应放在CN中，因为它会显示给用户 . 虽然它已被弃用，但并未被禁止 .

相反，DNS名称应该包含主题备用名称 . 应该有两个 . 第一个是 lucidpress.com ，第二个是 *.lucidpress.com . 您只需 lucidpress.com 因为通配符需要匹配标签 .

作为参考，IETF在RFC 6125第3.1节服务器标识中弃用CN中的DNS名称;第6.4.4节检查通用名称 .

CA /浏览器论坛在Baseline Requirements（BR）第9.2.2节“主题公共名称”字段中弃用CN中的DNS名称 . 此外，根据CA / B，主题替代名称是必需的 . 请参见第9.2.1节“主题备用名称扩展” .

相关：RFC 6125，第6.4.3节，也不允许 *.lucidpress.com 与 lucidpress.com 匹配 . CA / B BR在第11.1.3节中介绍了通配符，但没有讨论匹配规则 .

有了上面的背景信息和下面的证书，这里是正在发生的事情 .

您在默认证书中有2个名称 . 它默认由Apache服务，因为它的first virtual host in the configuration file .

lucidchart.com
*.lucidchart.com

Lucid Press'证书中有2个名字 .

lucidpress.com
*.lucidpress.com

我认为不同的是服务器名称指示（SNI） . 它是TLS扩展，因此您需要TLS 1.0或更高版本 . 那些没有问题的人可以获得Lucid Press认证并使用TLS 1.0或以上与SNI;那些有问题的人获得默认证书并使用SSLv3或没有SNI . Windows XP将使用TLS 1.0但不使用SNI，因此由于部署基础，它经常在现场使用 .

浏览器接受它，因为它们使用TLS 1.0或更高版本并发送SNI扩展 . 因为SNI允许您的Apache服务器在握手期间选择适当的证书，所以没有名称匹配问题 .

Java拒绝它，因为它使用SSLv3，即使你说 SSLContext.getInstance("TLS"); . 你必须跳过一些箍，以确保你真正获得TLS 1.0及以上 . 有关Stack Overflow的一些问题 . 例如，参见Which Cipher Suites to enable for SSL Socket? .

Python 拒绝它，因为我猜你正在使用2.x，或者你正在允许SSLv3 . 你需要3.0或更高才能获得SNI . 请参阅Python FAQ上的Python 3 Support? .

wget 在version 1.14中添加了对SNI的支持 . 我怀疑 wget 没有启用它或使用SSLv3 .

cURL 可能确保使用SNI（如果可用） . 丹尼尔是非常彻底的，他试图确保无故障体验和开箱即用的安全姿势 .

在OpenSSL转储中，感兴趣的选项是 -tls1 -servername . 您可以通过省略 -servername 来获得没有SNI的TLS . 所以你需要 tls1 和 -servername <host> .

$ openssl s_client -tls1 -servername www.lucidpress.com \
     -connect www.lucidpress.com:443 | openssl x509 -text -noout
