Crate Docs Build Status Apache2/MIT licensed Rust Version Project Chat

Pure Rust implementation of the JSON Web Key (JWK) component of the Javascript Object Signing and Encryption (JOSE) specification as described in RFC7517.

A JWK is a way to represent cryptographic keys in JSON, typically public keys. This format contains information about how the key needs to be used so a child node can validate what a parent node sends (e.g. with JWTs) or encrypt messages for the parent node using this key (e.g. with JWEs). This crate provides data structures to interface with this format.
