c# - .NET Core 中的 SignedCms 替代方案

Question

.NET Core 中是否存在 System.Security.Cryptography.Pkcs.SignedCms 类的替代方案？还是我必须深入研究 BouncyCaSTLe，就像他们在 WinRT 案例中所做的那样？ Is there an alternative of SignedCMS in WinRT?

Answer 1

仅供引用，以防有帮助。似乎可以通过此 NUGET 程序包获得对 SignedCms 和 S/MIME 的其他基本 .NET 类的支持:

System.Security.Cryptography.Pkcs

即在将此 NUGET 包添加到我的 Visual Studio 2017 (VS2017) .NET Core 项目之前，我收到了以下编译错误:

添加NUGET包后，编译成功。
