MatrixCipher lets you turn messages into encrypted, shareable URLs instantly.
MatrixCipher is a client-side encrypted messaging tool that transforms plain text into shareable URLs. It runs entirely in the browser, requiring no server-side message storage, no accounts, and no database setup. Just type your message, generate the encrypted link, and share it.
Built with a sleek retro terminal-inspired interface, MatrixCipher keeps everything lightweight and fast while giving users a simple way to create encrypted message links on demand.
✅ Client-Side Encryption – Encrypt messages directly in the browser.
✅ URL-Based Sharing – Messages are stored in the URL fragment for instant sharing.
✅ No Backend Required – No database, no user accounts, no server-side message handling.
✅ Optional URL Compression – Uses compression to create shorter, more shareable links.
✅ Instant Decryption – Open a valid MatrixCipher link and decrypt the message instantly.
✅ Clipboard Integration – Quickly copy generated links or the current URL.
✅ Minimal Terminal UI – Clean cyberpunk-inspired interface with a simple workflow.
✅ Rich Text Input Handling – Message input is converted into plain text before processing.
✅ Single-File Deployment – Easy to host and run from a single HTML file.
✅ Mobile Friendly – Responsive layout for desktop and mobile browsers.
MatrixCipher uses a number of open-source tools to work properly:
- CryptoJS – Handles AES-based encryption and decryption in the browser.
- LZString – Compresses encrypted data for shorter URLs.
- Alpine.js – Powers the app’s lightweight reactive behavior.
- Tailwind CSS – Used for styling and layout.
- TailwindCSSMod – Custom styling utility used in the interface.
MatrixCipher is fully web-based – no installation needed.
To run locally:
git clone https://github.com/michaelsboost/MatrixCipher.git
cd MatrixCipher
To preview MatrixCipher locally, use a simple Python server:
python3 -m http.server 8000
Then open http://localhost:8000 in your browser.
You can also deploy the HTML file directly to any static host.
MatrixCipher follows a simple workflow:
- Type your message into the editor.
- Click to generate an encrypted URL.
- The message is encrypted in the browser.
- The encrypted output is optionally compressed.
- The result is stored inside the URL fragment (
#). - Share the full URL with the recipient.
- Opening the link allows the app to read and decrypt the message locally.
Because everything happens in the browser, there is no message persistence on a server. The encrypted payload lives entirely in the URL.
MatrixCipher was built for people who want a fast, simple way to share encrypted messages without relying on a backend or complicated setup.
It is ideal for:
- Sending quick private notes
- Sharing encoded messages through a link
- Lightweight browser-based encryption workflows
- Static hosting with zero server logic
- Experimental or educational crypto-inspired projects
MatrixCipher includes:
- A terminal-inspired encrypted message editor
- One-click URL generation
- Instant decryption from URL hash
- Compression toggling for shorter links
- Status feedback for encryption, decryption, and clipboard actions
- Quick clear/reset functionality
The UI is designed to feel minimal, fast, and focused.
