Learn how a hybrid autokey cipher combines a passphrase with ciphertext feedback to make every encrypted message unique — and why CipherPigeon uses it.
You do not need a special messenger to keep a message private. CipherPigeon turns any channel into a secure channel by encrypting before you send.
Cloud sync, AI assistants, and always-on networks are convenient. They also expand your attack surface. Offline encryption keeps your secrets off the map.
End-to-end encryption protects messages in transit. Device-side encryption, like CipherPigeon, protects them before they ever enter the channel.
