AES-256-GCM Encryption
Military-grade authenticated encryption for every message, header, and stored key. Tamper-evident by design.
Secure Channels
Protocol-GradeEncrypted Communication
Signal-spec Double Ratchet, post-quantum hybrid key exchange, and a zero-knowledge architecture that stores nothing. Built for security teams who need to coordinate response when the network itself is the risk.
Cryptographic Foundation
What Protects Every Message
Every layer of the protocol is designed to minimize metadata exposure and maximize forward secrecy — even against quantum adversaries.

What Protects Every Message

Double Ratchet Protocol
Signal-spec key ratcheting provides forward secrecy and break-in recovery. Compromising one message reveals nothing else.
Post-Quantum Hybrid
X25519 + ML-KEM-768 (Kyber) hybrid key exchange. Resistant to both classical and quantum attacks, NIST-standardized.
Header Encryption
Message headers are encrypted alongside content. Even the server cannot see who is talking to whom, or when.
Full Sealed Sender
Sender identity is cryptographically sealed. The server routes messages without knowing origin — only the recipient can decrypt.
Plausible Deniability
Conversation transcripts cannot be cryptographically attributed to either party. No one can prove you said anything.
How It Works
Three Steps to Secure Communication
No phone number. No email. No personal data. Just a Hat — and encrypted channels that leave no trace.
Create a Hat
Generate an anonymous identity (a "Hat") with a single click. No registration, no personal information, no phone number required.
Communicate Securely
Start encrypted conversations or send one-time Dead Drops. Every message is end-to-end encrypted with post-quantum key exchange.
Burn Everything
Destroy your Hat and all associated channels instantly. Messages self-destruct, keys are zeroed. Nothing remains on the server.
🛡 Threat Model
What Protects Every Message
No system is invulnerable. Stating what we defend against — and where our boundaries are — is more credible than claiming absolute security.
