How ASTP Protocol Works

Anonymous Secure Transfer Protocol guarantees zero server knowledge

1

Local Key Generation & SHA-256

Alice generates a 32-byte X25519 Vault ID keypair locally. Her node calculates the SHA-256 fingerprint and encrypts the payload via ChaCha20Poly1305.

24h Blind Relay Dead Drop

The locked .vnet ticket is dropped onto a blind relay server. The server holds useless ciphertext with zero private key access and auto-purges after 24 hours.

TTL Auto-Purge: 24h RAM
3

Recipient Decrypt & Verify

Bob polls the relay with his matching private key, downloads the ciphertext, decrypts it locally, and verifies the SHA-256 hash to confirm untampered transit.

✓ Integrity Verified

Zero-Trust Architectural Pillars

🔑

No Account, No Email, No Identity Trace

Traditional services track IPs, metadata, and user accounts. VaultNet relies solely on mathematical X25519 Vault IDs generated on-the-fly. No central server ever knows who sent what file.

🛡️

ChaCha20Poly1305 AEAD + SHA-256

Files are locked into .vnet tickets using ChaCha20Poly1305 authenticated encryption with HKDF-SHA256 key derivation. Every payload is stamped with a SHA-256 checksum for 100% untampered integrity validation.

Direct Local Wi-Fi P2P Mode

When Alice and Bob are on the same local network, VaultNet bypasses cloud infrastructure completely, streaming encrypted files directly socket-to-socket on port 9876.
