irisJWT

irisJWT is an ObjectScript library for JWT (JSON Web Token) encoding and decoding in InterSystems IRIS. It supports both symmetric (HMAC) algorithms and allows optional custom headers.

Features

• Encode payloads into JWTs
• Decode and verify JWTs
• Optional custom headers
• Symmetric (HS256) support by default
• Compatible with IRIS 2024.1+ (uses latest classes)

Future Implementation

• Asymmetric JWT Support (RSA / EC)

Installation

1️⃣ Install via ZPM (InterSystems Package Manager)

ZPM> INSTALL irisJWT

⚙️ Installation

Clone the Repository

git clone https://github.com/AshokThangavel/irisjwt.git
cd irisjwt

Running the Application with Docker

Build and start the app using Docker Compose:

docker-compose up --build

Stopping the Application

To stop and remove the running containers:

docker-compose down

Usage

Set token = ##class(irisjwt.JWT).Encode(payloadDAObject, secret, algorithm, headerDAOject) ; returns JWT token
Set payload =  ##class(irisjwt.JWT).Encode(token, secret, algorithm) ; retuns %DynamicObject
Set supportedAlog =  ##class(irisjwt.JWT).SupportedAlgorithms() ; returns supported alogrithms

The Encode and Decode methods return the JWT string or decoded payload on success. If an error occurs, they return an empty string ("").
You can check the following variables for details:

• %jwterror → Contains the exact error message.
• %objlasterror → Contains detailed error information for debugging.
