Discover how our advanced security features work together to provide you with the most private messaging experience available.
Send and receive messages even when you're offline. Your messages are encrypted and stored securely on your device until the recipient is online.
Machine learning algorithms run on your device to detect abnormal behavior and potential security threats, providing real-time alerts.
Engage in group chats that are fully decentralized. Messages are only delivered when all members are online and authenticated, ensuring complete privacy.
Cipher Messaging eliminates all metadata, meaning no one knows who you talk to, when, or where you are.
Select the level of encryption that suits your needs—ultra-secure for sensitive conversations or optimized for performance in regular chats.
Access your app securely with biometric authentication (fingerprints, face recognition) as an additional layer of protection.
Enter a duress PIN to instantly wipe your data and send revocation messages to your contacts, ensuring no traces of communication remain.
Explore the technical architecture behind our most powerful security features.
Offline Messaging allows users to send encrypted messages even when they are not connected to the internet. The system stores messages securely on the sender's device, and once the recipient comes online, the message is transmitted in a peer-to-peer manner.
The sender creates a message, which is encrypted using XChaCha20-Poly1305 encryption.
The message is stored in an encrypted queue on the sender's device.
Once the recipient's device is online, the message is delivered directly using secure peer-to-peer communication.
The message is decrypted on the recipient's device and is erased after being read.

Cipher Messaging is built for people who need the highest level of privacy and security in their communications.
Protect your sources by ensuring complete anonymity and eliminating the risk of metadata being traced back to you.
Coordinate and communicate without exposing your location, social network, or communication patterns to surveillance.
Maintain attorney-client privilege with complete confidentiality, ensuring no third parties can access your conversations.
Take control of your privacy with a decentralized messaging platform designed to keep your identity and messages safe from surveillance.
Under the hood, Cipher Messaging uses state-of-the-art cryptographic algorithms and protocols.
We use XChaCha20-Poly1305, a high-speed and secure authenticated encryption algorithm, to encrypt your messages. This ensures that only the intended recipient can decrypt and read the message.
Ed25519 is used for identity signing, ensuring that the communication cannot be tampered with and is verified by the recipient's device.
We use X25519 for secure key exchange during the encryption process. This ensures forward secrecy, meaning that even if a long-term key is compromised, past messages cannot be decrypted.
Forward Secrecy ensures that even if a private key is compromised in the future, it cannot be used to decrypt past conversations. This is achieved by rotating keys for each session.
