如何使用USB令牌和capicom工具在ASP.NET中对XML文件进行数字签名？

Question

我想知道如何使用USB令牌在ASP.NET C＃中对XML文件进行数字签名？

我想知道如何从mosearbear USB令牌获取证书并使用其中包含的私钥对XML文件进行数字签名？

由于 USB在客户端计算机上，我想在客户端系统上签署XMl文件，那么如何做到这一点？

我所知道的是不容易在客户端计算机上访问设备，但是 我已经知道它可以用capicom完成，但不要“知道如何 。

我最近得知的是微软停止使用capicom。那又有什么选择？

我有一些代码，但这似乎不是我想要的。任何人都可以帮助我吗？
