What Is Military-Grade Encryption?
Quick Answer
Military-grade encryption typically refers to AES-256, the same encryption standard approved by the NSA for TOP SECRET information and used by militaries worldwide.
Detailed Explanation
'Military-grade encryption' is a marketing term, but it has a real technical basis: AES-256 encryption, which the US National Security Agency (NSA) has approved for encrypting TOP SECRET classified information. When a service advertises 'military-grade encryption,' they should mean AES-256 or equivalent. However, encryption strength alone isn't enough — implementation matters. A service using AES-256 but storing keys on its servers isn't truly secure. zkChat uses AES-256-GCM (the authenticated mode, which adds tamper detection) with keys that never leave the client browser. This is genuine military-grade encryption with proper key management.

What Is AES-256 Encryption?
AES-256 is the Advanced Encryption Standard with a 256-bit key — the same encryption used by the US military, banks, and governments worldwide. It's considered unbreakable.
Is End-to-End Encryption Really Secure?
Yes. Properly implemented E2EE using algorithms like AES-256-GCM is mathematically secure — breaking it would take longer than the age of the universe with current technology.
How Does End-to-End Encryption Work?
Your device encrypts the message before sending it. Only the recipient's device can decrypt it. The server in between only sees scrambled data it cannot read.
