http2https 🚀

Made by Aryan Giri

http2https is a Python-based CLI tool that helps you access an HTTP-only local service through HTTPS.

It is useful when a browser, client, or tool expects a secure https:// address, but your actual service is still running on plain HTTP.

---

What it does

Your service runs locally on HTTP, for example:

HTTP server:  localhost:8000

Then http2https runs an HTTPS proxy, for example:

HTTPS proxy:  localhost:8080

So instead of opening:

http://IP:8000

you open:

https://IP:8080

The tool accepts the secure connection, decrypts it locally, forwards the request to your HTTP server, and sends the response back to the client.

Why this is useful

Some tools and browsers expect HTTPS by default, even when the backend service itself only speaks HTTP. This tool helps in situations like:

• local development servers
• internal dashboards
• AI tools running on HTTP
• cybersec tools and lab panels
• browser testing on modern HTTPS-only environments

---

Features

• automatic TLS certificate generation
• Subject Alternative Names support
• CA-style certificate flags for browser compatibility
• custom certificate title
• reuse or regenerate existing certificates
• reverse proxy from HTTPS to HTTP
• simple CLI experience
• designed for local use

Installation

Clone the repository

git clone https://github.com/giriaryan694-a11y/http2https
cd http2https

Standard Python installation

pip install cryptography pyfiglet termcolor colorama requests

Termux installation

If you are using Termux, do not install cryptography with pip first. Use the Termux package instead to avoid build errors.

pkg update && pkg upgrade
pkg install python python-cryptography
pip install pyfiglet termcolor colorama requests

---

Usage

1. Start your local HTTP server.

Example:

python -m http.server 8000

2. Run the tool.

python main.py

3. Enter the requested details.

Typical values:

• Certificate Title: MyDevCA
• Domains / IPs: localhost, 127.0.0.1, 10.192.37.173
• Internal Port: 8000
• HTTPS Port: 8080

4. Open the HTTPS proxy in your browser.

Example:

https://127.0.0.1:8080

Trusting the certificate

To avoid browser certificate warnings, install the generated certificate as a trusted root certificate on your system.

Windows

1. Open the generated certificate file.
2. Click Install Certificate.
3. Choose Current User.
4. Select Place all certificates in the following store.
5. Choose Trusted Root Certification Authorities.
6. Finish the wizard.
7. Restart your browser.

Linux

Install the certificate into your system trust store using your distro’s certificate management method.

Android

Import the certificate through the device security settings if your device supports user certificate installation.

---

Notes

• This tool is intended for local or authorized development use.
• Keep the certificate and proxy endpoint private.
• If you change domains or IPs, regenerate the certificate.
• The proxy only bridges HTTPS to an HTTP backend; it does not turn the backend itself into an HTTPS server.

Example flow

Browser / Client
        ↓ HTTPS
http2https proxy on 8080
        ↓ HTTP
Local service on 8000
