ICP HTTP Proxy

This application is currently only a proof of concept implementation and should be used at your own risk.

Overview

An implementation of the ICP HTTP Gateway Protocol that enables end-to-end secure connections with dApps being served from the Internet Computer.

Motivation and Goals

• Connect to the ICP network without the need for any trusted intermediaries.

• Verify HTTP responses received from the ICP network for authenticity.

• Resist censorship by bypassing traditional DNS infrastructure.

• Enable resolution of crypto domains (not implemented yet).

Key Features

• Translate between ICP API calls and HTTP Asset Requests.

• Terminate TLS connections locally with a self-generated root certificate authority.

• Detect IC domains from principals and custom domain DNS records.

• Bypass remote HTTP gateway denylists.

Supported Platforms

• Windows

• MacOSX

• Debian

Other platforms can also be supported by adding the generated root certificate to the device's trusted store and adding the proxy HTTP server to the active network interface configuration.
