NSign.Abstractions

Abstractions for signing and verification of signatures on HTTP messages. The abstractions by themselves are not very meaningful in most cases, as they contain mostly interface definitions and abstract base classes. They are useful though for building more extensions, or also things like middleware for other web server stacks or HTTP clients other than the ASP.NET Core stack, for which the package NSign.AspNetCore already provides middleware, or the HttpClient class from the System.Net.Http namespace, for which the NSign.Client package already provides the middleware.

And, just as important, the package NSign.SignatureProviders holds implementations for standard signature algorithms outlined in RFC 9421 ¹.
