IdentityModel is a .NET library for claims-based identity, OAuth 2.0 and OpenID Connect.
It provides an object model to interact with the endpoints defined in the various OAuth and OpenId Connect specifications in the form of:
- types to represent the requests and responses
- extension methods to invoke requests
- constants defined in the specifications, such as standard scope, claim, and parameter names
- other convenience methods for performing common identity related operations
IdentityModel targets .NET Standard 2.0, making it suitable for .NET and .NET Framework.
