SecuAuth Authentication Service

Enterprise-grade authentication powered by military-grade AES encryption and a battle-tested Microsoft-developed challenge-response protocol.

Security Features

Session Security

Session tokens are cryptographically signed using HMAC-SHA256 to prevent tampering. All cookies are scoped with HttpOnly, Secure, and SameSite=Strict flags.

Input Validation

All user-supplied input is sanitized server-side to prevent injection attacks. Our parameterized queries and strict type checking eliminate SQL injection, XSS, and path traversal vectors.

Key Rotation

Shared secrets are automatically rotated every 24 hours using a deterministic KDF chain derived from the initial registration secret. Stale keys are securely zeroed from memory after rotation.
