What Happens When an Encrypted App Gets Hacked?
Quick Answer
It depends on the architecture. If the app stores data on servers, hackers get that data. With zero-knowledge architecture like zkChat, hackers get only encrypted blobs they can't decrypt.
Detailed Explanation
When a messaging service gets breached, what hackers obtain depends entirely on what the server stores. Telegram breach: access to all non-secret-chat messages in plaintext. WhatsApp breach: access to metadata, contacts, groups, and potentially unencrypted backups. Signal breach: minimal data (phone numbers and last-seen timestamps). zkChat breach: encrypted blobs that are cryptographically impossible to decrypt (keys are never on the server), no user identities (no accounts exist), no metadata (none is collected), and most data would already be destroyed (ephemeral). This is why zero-knowledge architecture matters — it's not about preventing breaches (which are always possible), it's about making breaches worthless.

Are Encrypted Messages Safe from Hackers?
Yes — properly encrypted messages using AES-256-GCM cannot be decrypted by hackers. The bigger risk is the service itself being hacked, which is why zero-knowledge matters.
What Is Zero-Knowledge Encryption?
Zero-knowledge encryption means the service provider is technically unable to access your data — not just promising not to, but cryptographically prevented from doing so.
Can Encrypted Messages Be Intercepted?
Encrypted messages can be intercepted in transit, but they appear as meaningless scrambled data. Without the decryption key, intercepted ciphertext is useless.
