我正在尝试构建一个使用的自托管服务,WebAPI
并且SSL
我需要能够自生成 SSL 证书才能使用。我希望能够从C#
. 我一直在玩BouncyCastle
。
我需要生成 2 个证书,一个根证书和一个站点证书。然后我需要将它们安装在 Windows 中的正确位置。
我不知道如何让我的第二个证书引用我的根 ca。我尝试过的所有事情都会让我遇到一个不受信任的证书错误。任何帮助,将不胜感激。

这就是我所做的(我使用的是 DSA,但如果您使用的是 RSA,只需更改密钥生成)。

另外:您必须将 CA 证书安装到客户端计算机的受信任 CA 存储中,以及客户端证书(它可能位于个人或第三方存储中)。
