Signal is an encrypted messaging platform built on the Double Ratchet protocol. Every message is a bioluminescent organism — alive only in the dark between two endpoints.
Six primitives that make Signal the most private messaging layer in the known universe.
Forward-secret key rotation on every message. Compromise one key, the past stays sealed.
Set a half-life. Messages decay into the void after seconds, minutes, or days — your call.
Even metadata is encrypted. Observers see only noise — no sender, no recipient, no pattern.
Post-quantum key encapsulation layered beneath classical curves. Ready for the next era.
Route through community-operated relays across the void. No single throat to choke.
Every line auditable. Reproducible builds. The protocol is the product, not a black box.
Signal runs end-to-end encryption by default. We never hold your keys, never log your metadata, never see your plaintext. The server is a relay — a dark current that carries light it cannot read.
Keys are generated on-device and never leave. The server cannot decrypt, even under subpoena.
X3DH + Double Ratchet, reviewed by independent security firms. Annual public audits published in full.
Identity is a cryptographic handle you control. No carrier, no directory, no leak surface.
// signal handshake — live trace → init session :: alice → relay → fetch prekey :: bob_identity_pub → derive shared :: hkdf(sha256, dh1|dh2|dh3) → root key :: 0x9f2a...c41e → chain key :: 0x4af6...e0b3 → message key :: 0x1d7c...88aa → ratchet step :: ← advance → → encrypt :: aes-256-gcm(payload) → transmit :: sealed_sender // relay forwards opaque bytes ✓ delivered :: bob decrypts locally // server saw nothing.
No accounts, no phone numbers, no central directory. Just cryptographic identity and the void between you.
Create an Ed25519 identity keypair on your device. Your handle is a fingerprint of that key — share it however you like.
→Send a message to a handle. Signal runs an X3DH handshake through a federated relay and derives a shared secret.
→Each message ratchets a new key. Forward secrecy guarantees past messages stay sealed even if a key leaks tomorrow.
The protocol is open source forever. Pay only if you want hosted relays, team controls, and deeper voids.
Full encryption for personal use. Self-host or use community relays.
Hosted relays, admin controls, and verified identity for small teams.
Dedicated relays, on-prem deployment, and SLA-backed voids.
