StackX Protect is the cryptographic foundation securing every layer of HexStack. From hardware-bound WebAuthn passkeys and binary delta-signature verification to isolated MinIO S3 data vaults, envelope encryption, and real-time socket defense, your digital assets remain invulnerable.
A multi-layered cryptographic barrier operating continuously across identity, distribution, storage, and transport.
HexAccount leverages FIDO2/WebAuthn hardware passkeys, cloned authenticator detection via monotonic signCount, RFC 6238 TOTP, and single-use recovery codes. Credentials never traverse plaintext.
Applications published to PlayStack undergo sandboxed Rust static analysis (apk-guard-core), Zip-Slip path validation, Shannon entropy dex inspection, and continuous background hash audit re-scanning.
Hardware-backed envelope encryption wraps AES-256-GCM data encryption keys under a master KEK. Supports zero-plaintext in-flight key rotation, isolated MinIO S3 vaults, and presigned access tokens.
High-speed edge WAF screens SQL injection, Command Injection, and Path Traversal with ReDoS-safe patterns, sliding-window rate limits, and Circuit Breaker auto-quarantine ladders with <100ms session stamp revocation.
Signal-style Double Ratchet and X3DH architecture with cryptographic pre-key bundles (Identity Keys, Signed Pre-Keys, atomic OTPKs), ephemeral blind mailbox routing, and 60-digit canonical safety numbers.
Privacy-preserving subnet truncation (/24 & /48) and daily rotating salts enable distributed attack correlation without user tracking. Client RootDetector and AntiTamper probes shield mobile devices.
How StackX Protect proactively counters modern cyber threats and surveillance vectors.
