deBeam vs Network Scan

deBeam transfers files directly between devices over local Wi-Fi at full network speed. --- HOW IT WORKS --- Pairing takes just 3 seconds. The receiver taps "Receive" to show a QR code. The sender scans it and taps "Send". Done. No usernames, no pairing codes, no waiting for cloud servers. --- WIRELESS TRANSPORT MODE --- Wi-Fi LAN (Same Network / Hotspot) Already on the same router or connected via a Mobile Hotspot? deBeam uses your existing local network path. Every device keeps its own IP, eliminating IP collisions. Fully cross-platform: transfer between iOS, iPadOS, macOS, and other mobile or desktop platforms with no setup required. Real-world speed: 50-100 MB/s. A 1 GB video transfers in under 20 seconds. High-performance local streaming without routing bottlenecks or cloud dependency. --- PROTOCOL-LEVEL END-TO-END ENCRYPTION --- Security in deBeam is the protocol itself, implemented at the lowest native layer. Key Exchange - X25519 ECDH Every session generates a new keypair from scratch using random bytes from the OS secure random number generator. The receiver's public key is embedded in the QR code. Scanning performs an X25519 Elliptic Curve Diffie-Hellman exchange, producing a shared secret that exists only on those two devices for that one session. The attacker space is 2^255 - computationally impossible to brute force. Key Derivation - BLAKE2b The shared secret is processed through BLAKE2b with the context string "deBeam-v3-session". This binds the derived key strictly to this protocol version, preventing key reuse or replay attacks. Encryption - ChaCha20-Poly1305 (AEAD) Every byte of your files is encrypted with ChaCha20-Poly1305. Files stream in 1 MB chunks, each with a unique nonce derived from its file index and chunk position. No nonce reuse: No two chunks ever share a nonce - cryptographic reuse attacks are impossible. Integrity: Each chunk carries a 16-byte Poly1305 authentication tag. Any tampered or replayed chunk is instantly detected and the connection terminates. Memory Security - crypto_wipe() After the key exchange, ephemeral private keys and session keys are immediately wiped from memory using crypto_wipe(). Past sessions cannot be recovered even if the device is compromised later. Threat Coverage Eavesdropping: Blocked by ChaCha20-Poly1305 encryption. Man-in-the-middle: Blocked by X25519 (cannot forge secret without private keys). Rogue device: Impossible without the QR-embedded public key. Brute force: 2^255 key space - mathematically infeasible. An 8-byte visual key fingerprint ("A1B2-C3D4...") on the receiver's screen allows quick visual verification before files move. --- NATIVE PERFORMANCE --- The encryption and streaming engine is written via native integration using Monocypher 4.0.2 - a compact, audited crypto library. ChaCha20-Poly1305 runs at ~500 MB/s on ARMv8. Encryption overhead is zero compared to Wi-Fi throughput - no speed penalty for maximum security. --- NO SERVER. NO CLOUD. NO ACCOUNT. --- deBeam has no backend infrastructure. No signup, no login, no tracking, no telemetry. QR pairing is computed entirely on-device and works 100% offline. Files travel directly from sender to receiver. --- CORE FEATURES --- Send multiple files in a single session All file types: videos, photos, docs, archives, RAW files, and custom formats Persistent local storage - chosen destination saved securely via Security-scoped Bookmarks No file size limit QR code pairing - no manual IP entry, no accounts Visual key fingerprint for authenticity verification Files saved securely to system Downloads or custom user-defined directory Real-time transfer progress per file Full cross-platform support across mobile and desktop devices deBeam. Beam it. Privacy Policy: https://devitan-docs.gitbook.io/devitans-apps/x.-privacy-policy-for-devitans-apps Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

KNOW WHAT IS ON YOUR NETWORK Network Scan discovers devices on the Wi-Fi networks you join and gives you a clear, private inventory on your iPhone and iPad. See responding hosts, names, likely device types, services, open ports, and last-seen details without creating an account. WAKE A COMPUTER FOR FREE Save a compatible machine and send a Wake-on-LAN magic packet from your phone or tablet. Wake works best with wired desktops and servers that have Wake-on-LAN enabled in firmware and the operating system. SSH IS PRO Use a real, interactive SSH terminal with multiple sessions and essential keys above the keyboard. On iPhone, the terminal fills the screen and a slide-up drawer keeps saved hosts and open sessions close at hand. On iPad, a persistent Connections sidebar keeps hosts and sessions visible beside the terminal. Pro also adds: - Wake + SSH in one tap. Wake the machine, wait for its SSH service, and connect automatically. - Sleep requests over SSH, with presets for Linux, macOS, and Windows. - Custom device names, larger port scans, CSV export, and full scan history. CURRENT, HISTORY, AND SAVED Keep today's network view separate from dated scan snapshots and the machines you intentionally save. Watch network can check for changes for up to 10 minutes while the app is open, with optional alert tones. PRACTICAL NETWORK TOOLS Use Ping, DNS lookup, TCP checks, port scanning, banner checks, subnet tools, and other focused diagnostics. Results stay connected to the work you started. PRIVATE BY DESIGN Network Scan has no app account, advertising SDK, analytics SDK, or SEM cloud service. Scan history and saved connections stay on your device. Passwords and private keys are stored in iOS Keychain only when you choose to save them. FREE AND PRO Network scanning, essential diagnostics, and Wake-on-LAN are free. SSH is Pro. - Yearly: $19.99 USD, with a 7-day free trial for eligible new subscribers. - Lifetime: $49.99 USD as a one-time purchase. - No monthly plan. Payment is charged to your Apple Account at purchase confirmation. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in App Store settings. A free trial converts to a paid subscription unless cancelled before the trial ends. Lifetime is a one-time purchase, not a subscription. Wake-on-LAN requires compatible hardware, host configuration, and local network access. Wake + SSH requires a reachable SSH service and saved credentials. Sleep requests require an SSH account permitted to suspend the host. A sent request does not by itself prove that the computer woke or slept. Use Network Scan only on networks and systems you own or are authorized to administer.
