Is End-to-End Encryption Really Secure?
Quick Answer
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.
Detailed Explanation
End-to-end encryption using AES-256 is considered computationally secure by every major intelligence agency and security researcher. A brute-force attack against a 256-bit key would require more energy than exists in the solar system. The real risks aren't with the math — they're with implementation: weak random number generation, key management flaws, or backdoors. That's why open-source implementations matter — anyone can audit the code. zkChat uses the Web Crypto API (browser-native, battle-tested crypto) and is fully open source for independent verification.

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.
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.
What Is Military-Grade Encryption?
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.
