Introduction

Cogito is an open-source identity management system. For a quick introduction, visit cogito.mobi or watch an introduction video. You may want to start by following the Tutorial or by browsing through the rest of this documentation.

Use cases

Identity

Use Cogito to identify the users on your website. Each user presents its own unique identifier, without the need for a username & password combo. Cogito identities are backed by a cryptographic private-public keypair. The private keys remain safely on the phones of your users.

Encryption

Enable end-to-end encryption between the user of your website without having to worry about key management. The private keys are safely stored on the phones of your users.

Blockchain transactions

Allow your users to interact with smart contracts on an Ethereum blockchain. The cryptographic signatures that are required are generated by Cogito.

API

The Javascript API allows webapps to identify Cogito users, provide end-to-end encryption using Cogito managed keys, and interact with Ethereum smart contracts.

We also provide convenience components for React based web apps.

Cogito Packages

More information about the individual components can be found in the Components section of the documentation.

Deployment overview

Web apps communicate with the Cogito mobile app through an end-to-end encrypted communication channel called Telepath. Web apps can also choose to interact with Ethereum contracts using the well-known web3.js api.

Cogito Deployment

The following overview illustrates how Telepath is used throughout all the packages and the demo app.

Telepath Usage Overview

Development

Cogito is still very much a work in progress. If you'd like to contribute, then you're more than welcome to. Our source code lives on GitHub. We wrote a guide to help you get started on your first contribution.
