Local Storage & Encryption

Data is encrypted using AES-GCM + RSA hybrid encryption, keys stored in system-level secure area (Android KeyStore). All data stored only on your phone, no cloud leak risk.

Mobile First Experience

Native experience built on .NET MAUI. Supports biometric unlock (fingerprint/face), scan code to enter TOTP, secure access anytime, anywhere.

Professional Security Architecture

We don't trust any intermediaries, including LAN. Passbox implements end-to-end encrypted transmission protocols.

  • HTTPS + Self-signed Certificate

    Dynamically generates SSL certificates on service start, ensuring encrypted LAN communication channels.

  • RSA + AES Hybrid Encryption

    Browser generates AES key and transmits to phone encrypted via RSA public key, subsequent communication fully encrypted, preventing MITM attacks.

  • Biometric Authorization

    Sensitive operations (like viewing passwords, exporting data) require biometric verification on phone, ensuring user identity.

var cipher = Cipher.GetInstance("AES/GCM/NoPadding");

// 使用 Android KeyStore 中的私钥

cipher.Init(CipherMode.DecryptMode, secretKey, spec);

// 验证生物识别并解密

var plainText = cipher.DoFinal(encryptedData);

// 只有授权成功才会执行到这里
