- End-to-end encryption is now standard; privacy debates must focus on metadata, identity exposure, and forensic traces.
- Three key security layers distinguish apps: cryptographic strength, identity anonymity, and forensic resistance.
- Signal excels in encryption but uses phone numbers, limiting anonymity; WhatsApp encrypts messages but collects metadata.
- Telegram lacks default end-to-end encryption and uses a criticized custom protocol; it's better for public channels.
- Session offers anonymity without phone numbers but lacks extensive cryptographic validation compared to Signal.
- xPal emphasizes full privacy: NIST-validated encryption, no phone number registration, and strong forensic resistance features.
- Real security requires holistic architecture, reducing data exposure beyond just encrypting message content.
