jwt 0.1.0

JWT

A Simple D implementation of JSON Web Tokens.

Supported Algorithms

• none
• HS256
• HS384
• HS512

How To Use

Encoding

import jwt.jwt;
import jwt.exceptions;
import jwt.algorithms;
import std.json;
import std.datetime;

void main() {

    Token token = new Token(JWTAlgorithm.HS512);

    token.claims.exp = Clock.currTime.toUnixTime();

    token.claims.set("id", 60119);

    string encodedToken = token.encode("supersecret");

    // work with the encoded token

}

Verifying

import jwt.jwt;
import jwt.exceptions;
import jwt.algorithms;

void main() {

    // get encoded token from header or ...

    try {

        Token token = verify(encodedToken, "supersecret", JWTAlgorithm.HS512);

        writeln(token.claims.getInt("id"));

    } catch (InvalidSignature e) {

        writeln("This token has been tampered with");

    } catch (ExpiredException e) {

        writeln("Token has expired");

    }

}

Limitations

• ##### Since Phobos doesn't support RSA algorithms this library only provides HMAC signing.
• ##### Currently this library only supports primitive data types(bool, string, int, float, double, null) in claims(working to remedy the situation)

Note

this library uses code and ideas from jwtd and jwt-go
