Trust & Transparency Center

At Paben VPN, user trust is built on verifiable technical design, not marketing claims. Here is our complete, transparent technical blueprint covering our encryption architecture, session memory policy, binary integrity, and user protections.

1

Cryptographic Architecture (WireGuard®)

Paben VPN exclusively utilizes the state-of-the-art WireGuard® protocol for tunneling network traffic. Unlike legacy IPSec/OpenVPN stacks containing hundreds of thousands of lines of code, WireGuard features a minimal attack surface (~4,000 lines of code) implementing modern cryptographic primitives:

  • ChaCha20-Poly1305: Authenticated symmetric encryption for all routed packets.
  • Curve25519: Elliptic-curve Diffie-Hellman key exchange for secure session establishment.
  • BLAKE2s: High-performance cryptographic hashing.
  • AES-256-GCM: Standard authenticated encryption used exclusively for securing stored credentials and API tokens at rest.

Zero Activity Logs & In-Memory Execution

We operate on a strict data-minimization principle. Our VPN gateway routing software executes within temporary volatile system RAM. We commit to the following operational invariants:

✓ Zero Browsing Logs: No tracking of destination IPs, domain lookups, or user traffic payload.
✓ Zero DNS History: Internal DNS requests resolved in-memory with no disk retention.
✓ Volatile Reboot: Any ephemeral session routing state is automatically purged upon system reboot.
✓ Minimal Account Data: Only email address and active subscription expiry are retained for billing verification.
