Zero-Trust Local Encryption Protected 100% of Sensitive Vault Data
Modern password managers store highly sensitive information including passwords, banking credentials, API keys, secure notes, and confidential documents. Protecting this information requires more than database encryption—it demands a zero-trust architecture where encryption keys remain inaccessible and sensitive data is never stored in plain text.
The Challenge
Solution & Architecture
Hardware-backed encryption is implemented
A unique AES-256 master key is securely stored using Android Keystore and iOS Keychain.
Field-level encryption is applied
Every password, note, API key, and financial record is encrypted individually before storage.
Authentication is strengthened
User PINs are secured using PBKDF2 key stretching with SHA-256 and random salts.
Plain-text storage is eliminated
Sensitive information and authentication credentials are never stored unencrypted.
Zero-trust security is enforced
Encryption keys remain protected by secure hardware throughout the application lifecycle.
