Majik Message

Majik Message is a private messaging platform built on cryptographic identity — not usernames, phone numbers, or email addresses. Your account is a pair of cryptographic keys derived from a 12-word seed phrase. Every message is protected by end-to-end post-quantum encryption, ensuring your privacy is safe from today’s threats and future quantum computers. How It Works • Seed Phrase Identity: When you create an account, Majik Message generates a 12-word BIP-39 mnemonic seed phrase. This phrase mathematically derives your unique X25519 (identity) and ML-KEM-768 (post-quantum) keypairs. • Argon2id Security: Your private keys are encrypted on your device using Argon2id, a modern, memory-hard key derivation function (KDF) that is highly resistant to GPU and ASIC cracking. • Hybrid Encryption: We use a hybrid cryptographic approach: ML-KEM-768 (FIPS-203) for post-quantum key encapsulation, X25519 for identity verification, and AES-256-GCM for message content. • No Personal Data: Your public key is your address. Share your "invite key" to connect—no phone number or email is ever required. Works Offline, No Registration Required You don't need an internet connection or an account to use the core encryption tools. From the Message tab, you can: • Encrypt text for one or more recipients entirely offline. • Decrypt any message addressed to you. • The output is a portable, self-contained string (prefixed ~*$MJKMSG:) that you can send via any channel (email, WhatsApp, or even paper). Real-Time Chats Unlock live messaging by registering your identity on the Majikah network. • Post-Quantum Delivery: Real-time messages use the same ML-KEM-768 security. • Automatic Expiry: Chat messages expire and are wiped from servers after 24 hours (expandable up to 30 days). • Group Chats: Secure conversations with up to 25 participants, with each message individually sealed for every member. • GIF support in chats • Emoji reactions in chats Threads — Immutable, Tamper-Proof Records Threads are designed for high-trust conversations that require a permanent, auditable record. • Blockchain-Like Integrity: Every message is cryptographically hashed and linked to the previous one, creating a tamper-evident chain. • Collaborative Deletion: A thread can only be deleted if all participants approve. • Secure Archival: Upon deletion, an encrypted JSON archive is emailed to all participants, which can be verified independently. Multi-Account & Cross-Platform Support 25 Local Accounts: Manage multiple identities on one device, each isolated and secured by its own seed phrase. • Chrome Extension: Use the companion extension to detect and decrypt ~*$MJKMSG: strings directly within your browser. • Secure Directory: Contacts are identified by verified public key fingerprints, stored locally and never synced to a server. Who Majik Message Is For Majik Message is for legal/healthcare professionals, journalists and security researchers who need verifiable message integrity. It is also for everyday users who believe their private conversations should stay private—guaranteed by mathematics, not just a privacy policy.

The Data Krypter

The easy way to keep your data secure well into the future when quantum computers become mainstream. -encrypts files, folders and blocks of text -when encrypting a file/folder, you can: - -give the file/folder a random name - -securely erase the original -makes your data useless to an attacker in case you are ever a victim of ransomware. But you need to prepare ahead of time by encrypting your sensitive files. Then the attacker cannot: - -use your data or - -threaten to make your files public -you can receive encrypted files from someone else and only one of you needs to have a paid version (or a non-expired trial version) of the Data Krypter. i.e. an accountant or lawyer pays for the software and all their clients can send encrypted files with a trial version (even if it has expired). -even if someone has access to your computer they can't decrypt your files because your: - -master password is encrypted - -private keys are encrypted - -secret keys are encrypted (stored only to help recover keys). -recovery any lost keys or master password with the Data Recovery module <== NEW -symmetric encryption (the same secret key to encrypt and decrypt) using PERNG -asymmetric encryption (public/private keys) using NTRU-2x2 -both types of encryption are quantum proof -send encrypted emails by encrypting the text then pasting it into an email -no back door
