About:
OpenSAML is a foundational C++ library that provides a comprehensive API for processing, creating, and consuming SAML assertions and protocol messages. It enables developers to integrate SAML-based Single Sign-On (SSO) and federation capabilities into custom applications and services. Its main value is offering a robust, low-level toolkit for building secure identity providers and service providers compliant with SAML 2.0 standards.

Key Features:

C++ API for SAML 2.0
Handles XML signing, encryption, and verification
Supports SAML protocol messages and assertions
Integrates with XMLTooling and OpenSSL

Use Cases:

Building custom SAML Service Providers (SP)
Developing SAML Identity Providers (IdP)
Integrating enterprise SSO into C++ applications

Alternatives:

Spring Security SAML – Java-based alternative offering higher-level configuration for Spring applications.
python3-saml – Python library providing SAML support, easier to integrate into web frameworks like Django.
