Encrypt and decrypt messages on any website. Secure chats with keypairs and seed-based accounts. Open source.

Majik Message: Post-Quantum Browser Encryption Majik Message Extension is a local-first security tool for encrypting and decrypting text directly within your browser. It is built on cryptographic identity rather than personal accounts—giving you total ownership of your private communications across any website or platform. Note: This extension focuses on local, offline encryption and decryption workflows. It operates entirely on your device and does not currently include real-time chat messaging or Threads. How It Works Quantum-Safe Encryption Anywhere • Highlight and Protect: Encrypt text on any website—from webmail and social media to document editors. Simply highlight text and use the right-click menu to transform your message into a secure cryptographic string. • Portable Output: Encrypted messages are generated as portable strings (prefixed with ~*$MJKMSG:) that you can share via any medium. Only your designated recipients with the correct keys can unlock them. Automatic Page Scanning & DOM Integration • Real-Time Detection: The extension scans web pages and input fields for ~*$MJKMSG: strings automatically. • Inline Decryption: When an encrypted message addressed to you is detected, it can be decrypted instantly without you ever leaving the page. Cryptographic Identity (No Accounts) • Seed Phrase Power: Your account is a 12-word BIP39 seed phrase—no email, phone number, or registration required. • Local-First Security: Your private keys never leave your device. They are encrypted at rest using Argon2id and are only loaded into memory during your active session. Why You Need Majik Message • Future-Proof Privacy: Protect your communications from future quantum threats today using ML-KEM-768 (FIPS-203) post-quantum encryption. • Zero Trust Architecture: You don't have to trust a company’s privacy policy when the software itself guarantees your security through mathematics. • Complete Ownership: You have full control of your data and keys; your messages are never sent to or stored by third parties. • Cross-Platform Portability: Easily back up or restore your account using a secure JSON file or your seed phrase.
