codefork/idunno.authentication

A filled with self-loathing implementation of Basic Authentication, and Certificate Authentication to make me feel like a real security person, all for for ASP.NET Core

idunno.Authentication

This repository contains a collection of various authentication mechanisms for ASP.NET Core, including

• Basic Authentication
• Certificate Authentication

Basic Authentication started as a demonstration of how to write authentication middleware and was not as something you would seriously consider using, but some people want Basic Authentication so here it is.

Certificate Authentication is a common request on the ASP.NET Core Security repo, so I wrote one for Core 2.x. ASP.NET Core 3.0 took that as a starting point and includes Certificate Authentication as a supported package.

Basic Authentication is available for ASP.NET Core 2.1, 3.0 and 3.1. Certification Authentication is only targeted at ASP.NET Core 2.1.

This is not an official Microsoft project, this is an "In my spare time, entirely unsupported"™ effort.

nuget packages

nuget packages are available for the ASP.NET Core 2.0 versions of the authentication handlers.

Authentication Type	Package Name	nuget link	Current Version
Basic	idunno.Authentication.Basic	https://www.nuget.org/packages/idunno.Authentication.Basic/	2.1.1
Certificate	idunno.Authentication.Certificate	https://www.nuget.org/packages/idunno.Authentication.Certificate/	2.1.1

Version History

Version	Notes
2.2.2	Basic auth now multi-targets Core 2.1, 3.0 and 3.1
2.2.1	Basic auth now returns a 421 request when a request is issued over HTTP, unless AllowInsecureProtocol is set
2.2.0	Basic auth no longer throws exception when invalid base64 data sent in authentication header Added property for suppressing the WWW-Authenticate header scheme Updated nuget license and package icon
2.1.1	Added SourceLink Changed library dependencies to remove demands for exact versions, following the .NET Core open-source library guidance nuget package is now signed
2.1.0	Added Certificate Authentication Fixed Basic Authentication event handling Packages are now Authenticode signed

What about older versions of ASP.NET Core?

Older versions of Basic Authentication are available in the appropriate branch. No nuget packages are available for ASP.NET Core 1.x.

Certificate Authentication is only available for ASP.NET Core 2.0. It will not be back ported to 1.x.

ASP.NET Core MVC Version	Branch
1.1	rel/1.1.1
1.0	rel/1.0.0

Notes

Each handler requires you to authenticate the credentials passed. You are responsible for hardening this authentication and ensuring it performs under load.
