Jose: Open-Source Cryptography Library

Jose is an open-source cryptography library that provides encryption and digital signature functions. It supports JSON Web Tokens (JWT), JSON Web Signatures (JWS), and JSON Web Encryption (JWE) standards.

What is Jose?

Jose is an open-source cryptography library written in JavaScript. It can be used both in Node.js backends and browser-based frontend applications.

Jose provides functions to encrypt, decrypt, sign and verify JSON data using popular standards like JSON Web Tokens (JWT), JSON Web Signatures (JWS) and JSON Web Encryption (JWE). It supports all JWS and JWE algorithms including HS256, HS384, HS512, RS256, RS384, RS512, ES256, ES384, ES512, PS256, PS384 and PS512.

A key benefit of Jose is that it builds on JavaScript native crypto APIs like Web Crypto API and Node.js crypto module instead of relying on external native libraries. This makes it very easy to integrate into JavaScript projects.

Some typical uses cases of Jose include:

  • Generating signed or encrypted JWTs for authentication
  • Signing and validating data sent to/from API servers
  • Encrypting/decrypting sensitive data at rest

Overall, Jose provides a light-weight set of functions to bring industry-standard cryptography capabilities to JavaScript applications.
