Encrypted by default, end to end.

Every request between your loader and this server travels inside an AES-256-GCM sealed envelope. Keys are derived per message, responses are bound to the request that asked for them, and nothing usable is ever stored in plaintext.

AES-256-GCM and HMAC-SHA256

Per message HKDF derivation, no key ever crosses the wire.

Replay and skew resistant

Nonce cache, timestamp window and response binding.

Sealed file delivery

DLL updates arrive compressed, chunk encrypted and hash verified.
