JWTDecode

This library will help you work with JWTs.

This library doesn't validate the token, any well formed JWT can be decoded from Base64.

Usage

To run the example project, clone the repo, and run pod install from the Example directory first.

Requirements

iOS 7+

Installation

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

pod "JWTDecode"

Or you can add A0JWTDecoder.h and A0JWTDecoder.m to your project.

###Decoding JWT token

NSString *jwt = @"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJodHRwczovL3NhbXBsZXMuYXV0aDAuY29tLyIsInN1YiI6ImZhY2Vib29rfDEwMTU0Mjg3MDI3NTEwMzAyIiwiYXVkIjoiQlVJSlNXOXg2MHNJSEJ3OEtkOUVtQ2JqOGVESUZ4REMiLCJleHAiOjE0MTIyMzQ3MzAsImlhdCI6MTQxMjE5ODczMH0.7M5sAV50fF1-_h9qVbdSgqAnXVF7mz3I6RjS6JiH0H8";
NSError *error;
NSDictionary *payload = [A0JWTDecoder payloadOfJWT:jwt error:&error];
NSLog(@"JWT payload is %@", payload);

let jwt = "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJodHRwczovL3NhbXBsZXMuYXV0aDAuY29tLyIsInN1YiI6ImZhY2Vib29rfDEwMTU0Mjg3MDI3NTEwMzAyIiwiYXVkIjoiQlVJSlNXOXg2MHNJSEJ3OEtkOUVtQ2JqOGVESUZ4REMiLCJleHAiOjE0MTIyMzQ3MzAsImlhdCI6MTQxMjE5ODczMH0.7M5sAV50fF1-_h9qVbdSgqAnXVF7mz3I6RjS6JiH0H8"
var error:NSError?
let payload = A0JWTDecoder.payloadOfJWT(jwt, error: &error)
println("JWT payload is \(payload)")

###Get JWT token expiration date

NSString *jwt = @"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJodHRwczovL3NhbXBsZXMuYXV0aDAuY29tLyIsInN1YiI6ImZhY2Vib29rfDEwMTU0Mjg3MDI3NTEwMzAyIiwiYXVkIjoiQlVJSlNXOXg2MHNJSEJ3OEtkOUVtQ2JqOGVESUZ4REMiLCJleHAiOjE0MTIyMzQ3MzAsImlhdCI6MTQxMjE5ODczMH0.7M5sAV50fF1-_h9qVbdSgqAnXVF7mz3I6RjS6JiH0H8";
NSDate *expireDate = [A0JWTDecoder expireDateOfJWT:jwt error:&error];
NSLog(@"JWT expire date is %@", payload);

let jwt = "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJodHRwczovL3NhbXBsZXMuYXV0aDAuY29tLyIsInN1YiI6ImZhY2Vib29rfDEwMTU0Mjg3MDI3NTEwMzAyIiwiYXVkIjoiQlVJSlNXOXg2MHNJSEJ3OEtkOUVtQ2JqOGVESUZ4REMiLCJleHAiOjE0MTIyMzQ3MzAsImlhdCI6MTQxMjE5ODczMH0.7M5sAV50fF1-_h9qVbdSgqAnXVF7mz3I6RjS6JiH0H8"
var error:NSError?
let expireDate = A0JWTDecoder.expireDateOfJWT(jwt, error: &error)
println("JWT expire date is \(expireDate)")

###Check if JWT token is expired

NSString *jwt = @"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJodHRwczovL3NhbXBsZXMuYXV0aDAuY29tLyIsInN1YiI6ImZhY2Vib29rfDEwMTU0Mjg3MDI3NTEwMzAyIiwiYXVkIjoiQlVJSlNXOXg2MHNJSEJ3OEtkOUVtQ2JqOGVESUZ4REMiLCJleHAiOjE0MTIyMzQ3MzAsImlhdCI6MTQxMjE5ODczMH0.7M5sAV50fF1-_h9qVbdSgqAnXVF7mz3I6RjS6JiH0H8";
BOOL expired = [A0JWTDecoder isJWTExpired:jwt];

let jwt = "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpc3MiOiJodHRwczovL3NhbXBsZXMuYXV0aDAuY29tLyIsInN1YiI6ImZhY2Vib29rfDEwMTU0Mjg3MDI3NTEwMzAyIiwiYXVkIjoiQlVJSlNXOXg2MHNJSEJ3OEtkOUVtQ2JqOGVESUZ4REMiLCJleHAiOjE0MTIyMzQ3MzAsImlhdCI6MTQxMjE5ODczMH0.7M5sAV50fF1-_h9qVbdSgqAnXVF7mz3I6RjS6JiH0H8"
let expired = A0JWTDecoder.isJWTExpired(jwt)
