About:
libjwt is a C library designed for creating and verifying JSON Web Tokens (JWTs). It provides a robust and portable solution for implementing authentication and authorization mechanisms in C-based applications. The library supports various JWT algorithms, including HS256, RS256, and ES256, ensuring secure token handling.
Key Features:
  • Support for multiple signing algorithms (HS256, RS256, ES256, etc.)
  • Pure C implementation for high portability
  • JWS (JSON Web Signature) and JWE (JSON Web Encryption) support
  • Integration with OpenSSL for cryptographic operations
Use Cases:
  • Implementing authentication in C-based web services and APIs
  • Securing microservices communication using JWTs
  • Validating tokens in embedded systems or backend daemons
Alternatives:
  • jwt-cpp – C++ library, whereas libjwt is pure C.
  • node-jsonwebtoken – Node.js specific, while libjwt targets C environments.
