Question

.NET Core中是否存在System.Security.Cryptography.Pkcs.SignedCms类的替代方法？或者我是否必须深入研究BouncyCastle，就像他们在WinRT案例中那样？ Is there an alternative of SignedCMS in WinRT?

Answer 1

不，目前还没有相当于.NET Core中的SignedCms。

非常欢迎您在https://github.com/dotnet/corefx/issues上创建一个问题，以表明它是您想要被带来的类型。

仅供参考，以防万一。
似乎可以通过此NUGET软件包获得对SignedCms和其他基本的S / MIME .NET类的支持：

System.Security.Cryptography.Pkcs

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

添加NUGET程序包后，我可以成功编译。
