Cylinder

Overview

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)
