Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

jwt-utils

JSON Web Tokens (JWT) utils.

npm version Build Status Coverage Status

This module is able to parse and generate both encrypted and unencrypted JWT tokens.

  • A hash key (hashKey) is needed to generate a JWT signature.
  • An encryption key (encryptKey) is needed only if you need to deal with encrypted JWT tokens.

This module only allows hexadecimal strings as hash and encryption keys. The encryption key must be a 32-length hexadecimal value (16 bytes) if the encryption algorithm is A128CBC.

The kid (key identifier) goes in the JWT header, and serves as a client identifier, in case you need to use different keys for different clients.

Installation

npm install jwt-utils

Examples

var config = { expiration: 600};
var jwt = require('jwt-utils')(config);

// Encode JWT token
jwt.buildJWT(payload, header, hashKey, function(err, token) {
    if (!err) {
        console.log(token); // something in the format "aaa.bbb.ccc"
    }
});

// Decode JWT token
jwt.readJWT(token, hashKey, function(err, token) {
    if (!err) {
        console.log(token.payload);
        console.log(token.header);
    }
});

// Encrypt JWT token
jwt.buildJWTEncrypted(payload, header, encryptKey, hashKey, function(err, token) {
    if (!err) {
        console.log(token); // something in the format "aaa.bbb.ccc.ddd.eee"
    }
});

// Decrypt JWT token
jwt.readJWTEncrypted(token, encryptKey, hashKey, function(err, token) {
    if (!err) {
        console.log(token.payload);
        console.log(token.header);
    }
});

// Read JWT header
jwt.readJWTHeader(token, function(err, header) {
    if (!err) {
        console.log(header);
    }
});

Configuration

  • expiration: Expiration time in seconds to generate exp field in token (this functionality can be disabled by setting the value to 0).
  • futureTolerance: Tolerance seconds to find out if a jwt comes from the future or not.
