JWTCodable

JWTCodable is a JSON Web Tokens decoder framework for iOS in swift.

📲 Installation

JWTCodable is available on CocoaPods:

pod 'JWTCodable'

if you want to use Decoder only you can install only JWTDecoder Readme

if you want to use Encoder only you can install only JWTEncoder Readme

📝 How

Code Implementation

import JWTCodable

Decoder

Example JWT Token

let jwtToken = "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c"

Header

{
  "alg": "HS256",
  "typ": "JWT"
}

Payload

{
  "sub": "1234567890",
  "name": "John Doe",
  "iat": 1516239022
}

Signature

HMACSHA256(
  base64UrlEncode(header) + "." +
  base64UrlEncode(payload),
  your-256-bit-secret)

Example Payload object

Create your own Payload object Codable, For example reference from payload JSON

struct Payload: Codable {
    var sub: String?
    var name: String?
    var iat: Int?
}

Decode to [String: Any]

let dict:[String: Any] = JWTDecoder.shared.decodeDict(jwtToken: jwtToken) 
// [String: Any]

Decode only Payload to Object

let payload:Payload? = JWTDecoder.shared.decodePayload(jwtToken: jwtToken, type: Payload.self) 
// Payload?

Decode to Object

let jwt:JWT? = JWTDecoder.shared.decode(jwtToken: jwtToken, payloadType: Payload.self) 
// JWT<Payload>?

jwt?.header 
// value as object JWTHeader?

jwt?.payload  
// value as object Payload? 
        
jwt?.signature  
// signature value as String?
        
jwt?.jwtToken  
// jwtToken value as String?

Encoder

Create JWT Token String

let header = JWTHeader(alg: .hs256)
let payload = Payload(sub: "1234567890", name: "John Doe", iat: 1516239022)
let signature = "SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c"
let jwt = JWT<Payload>(header: header, payload: payload, signature: signature)
// Create JWT Object

let jwtToken = JWTEncoder.shared.encode(jwt: jwt)
// Create jwtToken value as String?
