FILE ENCRYPTION
DESTROYS THE REST

AVGVSTO fuses your password with the physical fingerprint of any USB drive. Without the exact hardware, decryption is mathematically impossible — even if the password is known. Anti‑bruteforce, duress mode, 100% offline. VeraCrypt, BitLocker, AxCrypt are obsolete.

USB HARDWARE FINGERPRINT

serial + volumeID merged into key via PBKDF2. Any USB works, cloning fails.

  • 128-bit hardware salt
  • Emulation impossible

AES-256-GCM / CHACHA20

Authenticated encryption, indistinguishable from random. Pro: choose algorithm.

  • AES-NI acceleration
  • Poly1305 MAC

ANTI‑BRUTEFORCE ENGINE

After 3 failures, exponential backoff up to 1 month. Hard‑lock without reset USB.

  • 3 attempts → 1h lock
  • 6 attempts → 1 month

PLAUSIBLE DENIABILITY

Duress password reveals decoy files. Real data mathematically hidden. (Pro/Business)

  • Two separate key trees
  • Decoy FS

CASCADE ENCRYPTION

Business: AES‑256 → ChaCha20, independent keys. Future‑proof.

  • 512-bit effective
  • Post‑quantum resistant?

TAMPER‑PROOF AUDIT

Business: signed, immutable logs of every access attempt.

  • Ed25519 signatures
  • No deletion possible

Frequently asked

01 What happens if I lose the USB?
Your files are irrecoverable. That’s the point. Business tier includes a separate backup mechanism.
02 Can I use any USB drive?
Yes. Any brand, any capacity, FAT/NTFS/exFAT. Hardware serial is read, not volume label.
03 Is there a backdoor for password recovery?
Absolutely not. No cloud, no key escrow, no recovery codes. We are not sorry.
04 How does duress mode work?
Provide a special password during coercion; it reveals a decoy file. Real files remain hidden.
