A breakdown of the technologies and features that make Cipher Messaging the most secure, privacy-focused messaging platform.
Cipher Messaging uses cutting-edge encryption, zero metadata design, and decentralized communication to ensure that your conversations remain private and secure from start to finish. This page explains exactly how we achieve this.
Understanding the core concepts that make Cipher Messaging fundamentally different from every other messaging platform.
Messages encrypted on your device, decrypted only by the recipient. No intermediary can ever read your content.

Follow the journey of a message from creation to delivery, with complete privacy at every step.
Your message is instantly encrypted using XChaCha20-Poly1305 before it ever leaves your device. Military-grade encryption ensures only the intended recipient can read it.
The recipient receives an encrypted wake-up notification through Tor. This signal contains no message content or metadata about the sender.
The recipient authenticates using biometric data or their PIN. Keys are unlocked from the device's secure hardware enclave.
Your device establishes a direct peer-to-peer encrypted connection with the recipient. No intermediary servers can access the content.
Once the message is read, it's permanently deleted from both devices. No traces remain, ensuring perfect forward secrecy.
Deep dive into the four key architectural components that make Cipher Messaging the most secure platform.
Cipher Messaging uses a blockchain-based identity system, where each user's contact card is encrypted and stored on the Solana blockchain. This ensures self-sovereign identities without the need for personal information like email addresses or phone numbers.
