Secret messages via any app
Free
Hide encrypted messages inside normal text over WhatsApp, Telegram, Signal, iMessage or any app.
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, iMessage 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 encryption. 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.
Take back your absolute privacy today—without convincing your friends to download yet another chat app.
