What is a end-to-end encryption (e2ee)?
End-to-end encryption means only the sender and recipient can read a message; everything in between - including any server - sees only ciphertext.
The message is encrypted on the sender’s device and decrypted only on the recipient’s, using keys that never leave those devices. No provider in the middle can read it.
PrivaMesh goes further than typical E2EE apps: because there is no server in the middle at all, the only "ends" that exist are the two devices. It uses X3DH, the Double Ratchet and AES-256-GCM to seal every message.
