用Java访问本地机器证书存储区？

Question

是否可以从Java Servlet访问存储在本地计算机存储(而不是当前用户)中的证书？我尝试使用MSCAPI提供程序打开"Windows-MY"和"Windows-ROOT"存储,但都不包含本地计算机存储中的证书.

您要查找的证书位于 java keystore 文件中或在启动服务器时传递到 tomcat

http://tomcat.apache.org/tomcat-4.0-doc/ssl-howto.html

如果您尝试将它们加载到应用程序中，请在此处查找发出 HTTPS 请求，然后 HTTPClient 文档将帮助您入门

不确定这是否对您有帮助，但如果您可以提供更多详细信息，那么您也许可以获得更具体的答案
