The Rubber-Hose Threat Model
Standard encryption fails when an adversary physically seizes your unlocked device. Layergram provides a mathematically undeniable alibi in extreme 'rubber-hose cryptanalysis' scenarios.
Expellable Passphrases & Hidden Identities
Create secondary, completely isolated cryptographic identities protected by a secret passphrase. You can instantly 'expel' this identity from the device's RAM with a single tap.
The 'Lost Key' Alibi
If forced to open Layergram, your alibi is built into the protocol: 'Those messages belong to an old identity whose keys I have deleted.' Because the payload is signature-less, no forensic analyst can mathematically prove you are lying.
Local Metadata Blinding (Hive DB)
Inside the local Hive database, both the Message IDs and Timestamps are heavily encrypted. An adversary cannot reconstruct the timeline of your conversations without the exact key.
Perfect OpSec: Ephemeral Transport
Use Layergram with WhatsApp disappearing messages and Layergram's "Delete after read" feature. The ciphertext vanishes from both the transport servers and the recipient's local database.
Cryptographic Repudiation
Because Layergram uses ECDH (X25519) key agreement, the recipient has the mathematical ability to forge a message that looks exactly like it came from you. It is mathematically impossible to prove whether you authored the message, or the recipient forged it.
