答案 0 :(得分：0)
这只是意味着openssl无法找到CA的证书。检查openssl.cfg中提到的CA文件夹，然后将证书复制到那里。现在，它应该工作。
答案 1 :(得分：0)
根据您的转储，您需要CN=VeriSign Class 3 Public Primary Certification Authority - G5。您可以从VeriSign Root Certificates和Licensing and Use of Root Certificates获取。特别是，您需要Root 3 VeriSign Class 3 Primary CA - G5下载。
获得root后，通过s_client选项将其提供给-CAfile：
openssl s_client -CAfile PCA-3G5.pem -connect www.verisign.com:443
该命令将产生预期的结果：
$ openssl s_client -CAfile PCA-3G5.pem -connect www.verisign.com:443

这里只是自行车脱落，但可以改进：
SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP
也许以下密码套件列表对您和访客来说会更好一点。不需要SSLv2，低安全性密码和出口级密码。此外，它还删除了RC4（易于在SSL / TLS中使用）和MD5（远低于其理论安全级别）。
HIGH:!aNULL:!eNULL:!ADH:!MD5:!RC4:!SRP:!PSK
SRP和PSK实际上是首选密码套件，因为它们提供相互身份验证。但它们很少使用，所以不需要做广告。
