pgp-cipher

A minimal, browser-based tool for PGP encryption and decryption. All cryptography runs locally in your browser - no keys or messages are ever sent to a server.

Features

• Encrypt a message with a recipient's PGP public key
• Decrypt a message with your PGP private key (passphrase-protected keys supported)
• One-click copy of encrypted/decrypted output

Usage

Open index.html in any modern browser. No build step or install needed.

To serve it locally instead:

python3 -m http.server

Then visit http://localhost:8000.

Built with

• OpenPGP.js (loaded via CDN)
• Plain HTML, CSS, and JavaScript

Security note

Keys and messages stay in your browser tab. Still, only paste a private key into tools you trust, and prefer running this locally.
