Layergram

Standard encryption protects your data, but it still screams: "I have a secret." Layergram changes the game by hiding your encrypted messages in plain sight.

Layergram is not a new messaging app. It is a powerful, transport-agnostic encryption layer that allows you to send end-to-end encrypted messages over the platforms you already use—WhatsApp, Telegram, Signal, Discord, SMS, or even email.

How it works:

Type a normal, innocent-looking "cover message" (like a grocery list or a casual greeting). Then, type your highly sensitive "secret message". Layergram encrypts the secret data and steganographically weaves it into your cover text using invisible, zero-width Unicode characters.

To ISPs, chat platforms, and casual observers looking over your shoulder, it’s just a boring conversation. Only a Layergram client with the correct private key can trial-decrypt and reveal the hidden payload.

Key Features:

> Transport-Agnostic: Keep using your favorite apps. Layergram turns any text-based platform into a secure, visual-deniability channel.

> Military-Grade Cryptography: Powered by X25519 key agreement, HKDF-SHA256, and AES-GCM-256. Your private keys are generated locally and never leave your device.

> BIP39 Seed Phrase Backups: No complex key files to manage. Securely back up your cryptographic identity using a simple, standard sequence of words (BIP39), just like a crypto wallet.

> No Central Servers: We don't route your messages or store your data. You leverage existing networks, eliminating single points of failure.

> Signature-less Payloads: The hidden encrypted data is mathematically indistinguishable from random noise, protecting you against automated platform filters.

> Biometric & Anti-Screenshot Locks: Keep your decrypted secrets strictly for your eyes only, even if you hand your unlocked phone to someone else.

Advanced OpSec & Plausible Deniability:

Layergram is engineered to protect you not just from network surveillance, but from physical coercion ("rubber-hose cryptanalysis").

> Expellable Passphrases: Create completely hidden secondary identities. With a single tap, you can purge a hidden identity from your device's RAM.

> The "Lost Key" Alibi: Because Layergram payloads are signature-less, any encrypted data found on your device is mathematically indistinguishable from abandoned messages. No forensic analyst can prove otherwise.

> Local Metadata Blinding: Inside your local database, message IDs and timestamps are heavily encrypted, preventing adversaries from reconstructing your communication timeline.

Open Core & Auditable:

Security requires transparency. The core cryptography and the Layergram Message Format (LMF) protocol are open-source and available for public review.
