potatosalad/erlang-jose

This system is a cryptographic library for the Erlang and Elixir ecosystems, specifically designed to implement the JSON Object Signing and Encryption (JOSE) standards. It provides comprehensive support for JSON Web Encryption (JWE), JSON Web Signature (JWS), and JSON Web Tokens (JWT), enabling users to encrypt, sign, and verify data using a wide array of modern algorithms including Ed25519, ChaCha20-Poly1305, and RSA. The architecture is modular, allowing for flexible JSON backend selection and dynamic configuration of cryptographic backends, while maintaining rigorous correctness through extensive test vectors and property-based testing.

How it got here

2015 · Elixir API and cryptographic refactoring

This period focused on restructuring the library's internal architecture and introducing a high-level Elixir API for JSON Web standards. The work included significant internal refactoring to improve modularity, alongside the addition of comprehensive test suites and property-based tests for cryptographic algorithms.

2016–2023 · Modern cryptographic algorithm support

This period focused on expanding cryptographic capabilities by adding support for modern algorithms like Ed25519, Ed448, and ChaCha20-Poly1305. The codebase was updated to support multiple JSON backends and improved key agreement and wrapping mechanisms, while also refactoring internal code generation tools.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 6 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit c8b669c86d — the exact code this score is about.
  • Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
