JWSETKit

A library for working with JSON Web Signature (JWS) and JSON Web Token (JWT).

Overview

JSON Web Signature (JWS) represents content secured with digital signatures or Message Authentication Codes (MACs) using JSON-based RFC7159 data structures. The JWS cryptographic mechanisms provide integrity protection for an arbitrary sequence of octets.

JSON Web Token (JWT) is a compact claims representation format intended for space constrained environments such as HTTP Authorization headers and URI query parameters.

This module makes it possible to serialize, deserialize, create, and verify JWS/JWT messages.

Supported Swift Versions

This library was introduced with support for Swift 5.8 or later.

Getting Started

To use JWSETKit, add the following dependency to your Package.swift:

dependencies: [
    .package(url: "https://github.com/amosavian/JWSETKit", .upToNextMinor(from: "0.19.0"))
]

Note that this repository does not have a 1.0 tag yet, so the API is not stable.

You can then add the specific product dependency to your target:

dependencies: [
    .product(name: "JWSETKit", package: "JWSETKit"),
]

Usage
