Local File Encryption
Overview
Local File Encryption transforms your sensitive data into an unbreakable vault in your hands, encrypting files client-side into a ULF (UnoLock Encrypted File) that you can download and send to any cloud storage provider, with only you holding the key to decrypt it. Available across all tiers, Free, Inheritance, Sovereign, and HighRisk, this feature ensures that your files, from personal documents to cryptocurrency keys, remain private and secure, untouchable by UnoLock or third-party services. UnoLock’s zero-knowledge design guarantees that your data’s sovereignty travels with you, wherever you store or share it.
How It Works
- Client-Side Encryption: Files are encrypted on your device using AES-256 GCM, ensuring confidentiality and integrity before any transmission or storage.
- ULF File Creation: Encrypted files are saved as a ULF (UnoLock Encrypted File), downloaded locally to your device, ready for secure sharing or storage.
- Cloud Storage Flexibility: ULF files can be sent or uploaded to any cloud storage provider (e.g., Dropbox, Google Drive, OneDrive), with only you able to decrypt them using your locally stored key.
- Zero-Knowledge Key Management: Unique encryption keys are generated and stored on your device, never shared with UnoLock or third parties, ensuring exclusive user control.
Security Implications
- Zero-Knowledge Privacy: UnoLock has no access to your encryption keys or unencrypted data, ensuring complete privacy, even when ULF files are stored externally.
- Portable Security: ULF files remain encrypted and secure on any cloud storage platform, protected from unauthorized access by third parties or service providers.
- End-to-End Protection: From local encryption to secure transmission via TLS 1.3-encrypted channels (for UnoLock uploads), your data is safeguarded at every stage.
Use Cases
- Personal Data Sharing: Encrypt sensitive documents (e.g., tax records, medical files) as ULF files and store them on Google Drive or share via email, with only you able to decrypt.
- Business Collaboration: Companies can distribute encrypted client contracts or proprietary data as ULF files on Dropbox, ensuring only authorized recipients with keys can access them.
- Cryptocurrency Safety: Securely store wallet seed phrases as ULF files on OneDrive or a USB drive, protected from theft or exposure, with user-only decryption.
Why It Matters
Local File Encryption empowers you with a portable fortress of privacy, creating ULF files that safeguard your data across any cloud storage platform, accessible only by you. In a world of data breaches and surveillance, this feature ensures your sensitive information remains yours alone, wherever it resides.
FAQs
What is a ULF file, and how can I use it?
A ULF (UnoLock Encrypted File) is a locally encrypted file downloadable to your device, which you can store or send to any cloud provider (e.g., Dropbox, Google Drive), decryptable only with your key.
Can UnoLock or cloud providers decrypt my ULF files?
No, UnoLock’s zero-knowledge model ensures only you have the encryption key, and ULF files remain unreadable to cloud providers or third parties.
How secure is it to store ULF files on external cloud storage?
ULF files are encrypted with AES-256 GCM, ensuring they remain secure on any platform, as only you can decrypt them with your locally stored key.
Compliance & Privacy Regulations
- GDPR & HIPAA Compliance: Local File Encryption supports GDPR and HIPAA by encrypting data client-side and ensuring only the user can access it, maintaining privacy across any storage platform.
Integration with Other Features
- Post-Quantum Encryption Security: Enhances Local File Encryption with quantum-resistant AES-256 GCM, ensuring ULF files remain secure against future threats.
- FIDO2 Authentication with WebAuthn: Secures access to encryption keys with passwordless, phishing-resistant authentication, protecting the decryption process.
