Description
MiniOAuth2 is a lightweight, modern C++20 library that simplifies OAuth 2.0 Authorization Code Flow with PKCE. It is designed to integrate seamlessly with CrowCPP, but can be used in any C++ project thanks to its header-only architecture and minimal dependencies.
Highlights:
RFC-compliant Authorization Code Flow + PKCE
Secure token handling with URL-safe Base64 and SHA-256 (via PicoSHA2)
Optional support for nlohmann/json for parsing token responses
Standalone Google Login example using CrowCPP
No Boost. No linking. MIT licensed.
Whether you're building a web backend in C++, or need OAuth support for an embedded system, MiniOAuth2 provides a secure and minimal solution.
