Implements SAML v2.0 assertions, protocol, bindings and profiles.
ComponentSpace SAML for ASP.NET Core is a .NET class library that enables ASP.NET Core applications to participate in SAML v2.0 federated single sign-on (SSO). It provides APIs and middleware that manage SAML assertions, protocol messages, and security validation while integrating with the ASP.NET Core authentication and authorization pipeline. The library supports both service provider and identity provider roles for enterprise identity federation scenarios.

SAML V2.0 Protocol Implementation

Implements the OASIS Security Assertion Markup Language (SAML) v2.0 specification, including assertions, protocol messages, bindings, profiles, and metadata. The library provides a complete SAML implementation that handles message creation, transport, validation, and security processing within ASP.NET Core applications.

Service Provider And Identity Provider Roles

Allows applications to operate either as a SAML service provider (SP) or a SAML identity provider (IdP). This flexibility supports a range of federation architectures where applications authenticate users through external identity services or provide authentication for connected services.

Single Sign-On Workflows

Supports web browser single sign-on scenarios including both SP-initiated and IdP-initiated authentication flows. Applications can redirect users to identity providers for authentication and receive SAML responses that establish authenticated sessions within the application.

Single Logout Support

Implements SAML single logout (SLO) functionality, enabling coordinated logout across identity providers and service providers. This ensures that user sessions terminate consistently across participating systems within a federated identity environment.

XML Signature And Encryption Handling

Provides built-in support for generating and verifying XML signatures on SAML messages, assertions, and metadata. It also encrypts and decrypts SAML assertions, attributes, and identifiers to maintain message integrity and confidentiality during authentication exchanges.

Metadata Generation And Consumption

Generates and processes SAML metadata used to exchange configuration information between identity providers and service providers. This metadata defines endpoints, certificates, and protocol capabilities required for establishing trusted federation relationships.

SAML Queries And Identifier Management

Supports authentication, attribute, and assertion queries, along with name identifier management and mapping. These capabilities allow applications to retrieve identity information and manage user identifiers exchanged through SAML federation processes.

Identity Provider Discovery And Artifact Resolution

Includes support for identity provider discovery mechanisms and artifact resolution. These features allow applications to identify appropriate identity providers for authentication and resolve SAML artifacts into full protocol messages during secure exchanges.

ASP.NET Core Authentication Integration

Integrates with the ASP.NET Core authentication and authorization pipeline, enabling SAML authentication to work alongside existing application security infrastructure. This integration allows developers to incorporate federated login flows within standard ASP.NET Core identity workflows.
