3月20日的aWallet Password Manager应用程序分析

• Securely stores your passwords, credit card information, e-banking credentials, web accounts and other custom data. • There is a built in Editor for changing or creating new data Categories with custom icons. • Search within fields. • Contains no advertisements. • Supports backup and restore of the encrypted data file to the Android USB device. • Export of unencrypted data in CSV format to the USB device. • There is an Auto lock feature that can be preconfigured for a specific period of time. PRO FEATURES, available via single In-app billing payment: • Unlock with fingerprint (on a compatible device with Android 6) • Unlock with face (on a compatible device with Android 10 or later) • Password Generator • CSV Import SECURITY FEATURES • All data is encrypted, including Entry names, Category definitions and the data itself. Even the choice of Favorite Category is encrypted. • Encrypts data using AES or Blowfish algorithms with key sizes of 256, 192 or 128 bits. • When the data file is decrypted, up to all combinations of algorithm and key size are tried with the Master password to unlock the data file. The app itself does not store any hint to the actual cipher or key size. • Uses a randomly generated 'salt' combined with the Master password. Salt helps to protect from off-line dictionary attacks. • The key to open the data file is created by combining your master password with the 512-bit 'salt'. The result is hashed 1000 times by SHA-256. Repetitive hashing makes a brute force attack more difficult. • Supports auto destruction of the data file after a predefined number of unsuccessful unlocks have been tried. • Unlike other similar Android apps aWallet has no internet access permission (forever). The only permissions this app has is to access to the USB device to backup/restore the data file in case you lose your phone. USB device access is also needed to export to CSV file format. Permission is also granted to the Google Play billing service to allow for the optional purchase of the aWallet Pro features.
