Cylinder provides a simple and practical cryptographic signing and verification API for Rust projects. By building upon other cryptographic crates (such as secp256k1), Cylinder avoids implementing any cryptography directly.

Features include:

  • A Signer API for generating a signature by signing bytes with a private key
  • A Verifier API for verifying a signature for a given message and public key
  • A secp256k1 implementation of the Signer and Verifier APIs
  • Functions for finding and loading keys in a consistent manner
  • Support for Cylinder-compatible JSON Web Tokens (JWTs)
