swift-jwt

Swift Framework for JWT (JSON Web Token)

Created for Authentiq ID

Installation

Available in CocoaPods

SwiftJWT is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "SwiftJWT"

In case you want to use the project with Ed25519 algorithm support, you can install it using:

pod "SwiftJWT/with-ed25519"

Examples

import JWT

let jwt_str = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzY29wZSI6InBob25lIiwicGhvbmVfbnVtYmVyIjoiKzE2NTAyODU1NjAwIiwidHlwZSI6ImxhbmRsaW5lIiwiYXVkIjoiaHR0cHM6Ly9hdXRoZW50aXEuY29tIn0.CAqNpbmOA9lz9aq7Sp1NqqbdLJARmFKY3L7CKcgXLNU"

var jwt = JWT(algorithms: ["none","HS256"])
var j = jwt.loads(jwt_str, key: "secret")
let new_jwt_str = jwt.dumps("xxx")!

import JWT

let jwt_ed = "eyJhbGciOiJFZDI1NTE5IiwidHlwIjoiSldUIiwia2lkIjoiWE43VnBFWDF1Q3h4aHZ3VXVhY1lodVU5dDZ1eGdMYWhSaUxlU0VIRU5payJ9.eyJmb28iOiJiYXIifQ.a2dDcKXByKxiouOLnXUm7YUKHMGOU3yn_g91C90e8YmKjlF1_9ylAKukfMm6Y6WS3dZp2ysaglzzTnVxnRYyDQ"

let pk = "XN7VpEX1uCxxhvwUuacYhuU9t6uxgLahRiLeSEHENik"

var jwt = JWTNaCl(algorithms: ["Ed25519","none"])
jwt.loads(jwt_ed)
jwt.header["alg"] = "none"
println(jwt.dumps()!)

import JWT

jwt = JWT(header: ["alg":"HS256"],
    body: [
        "sub": "1234567890",
        "name": "John Doe",
        "admin": true
    ], algorithms: nil)
println(jwt.dumps("secret")!)

The Bridging Header

CommonCrypto is not a modular header in Xcode 7. This makes it very challenging to import into Swift. To work around this, the necessary header files have been copied into SwiftJWT.h, which needs to be bridged into Swift. You can do this either by using SwiftJWT as a framework, adding #import "SwiftJWT/SwiftJWT.h" to your existing bridging header, or making SwiftJWT/SwiftJWT.h your bridging header in Build Settings, "Objective-C Bridging Header."

Hopefully Apple will make CommonCrypto a modular header soon. When this happens, the bridging header will not be needed, and SwiftJWT can be a single file.
