Engineering Defense & Cryptography

Infrastructure Security &
Zero-Knowledge Defense.

How we engineer, isolate, and protect your account credentials, active sessions, and direct communications against modern web threats.

🔐
Transport Security

Strict TLS 1.3 & HSTS

All HTTP and WebSocket transmissions are encrypted using modern TLS 1.3 with Perfect Forward Secrecy (PFS), blocking packet sniffing and man-in-the-middle exploits.

🔑
Credentials Protection

One-Way Hash Derivation

Passwords are never stored in readable format. We enforce high-factor salted Argon2/Bcrypt key stretching, rendering offline brute-force attacks computationally infeasible.

💻
Session Management

Active Session Revocation

Inspect every active browser or mobile session with IP and timestamp metadata. Remotely terminate unrecognized logins with a single tap from Account Settings.

Architecture Layers

Defense-in-Depth Mechanisms

Automated Media EXIF Stripping

Raw camera photos frequently carry embedded GPS coordinates, camera serial numbers, and home timestamps. Our ingestion workers automatically scrub this metadata before images are saved to disk, preserving physical privacy.

Sliding Window Rate Limiting

Distributed Redis token buckets throttle suspicious velocity bursts: authentication attempts, password resets, follower queries, and message broadcasts are capped to halt credential stuffing.

Bug Bounty & Disclosure

Responsible Vulnerability Disclosure

We welcome security researchers and ethical hackers who assist in keeping FriendsBook and AXIONIK infrastructure safe. If you discover a vulnerability:
