What is ShieldFive?

Zero-Knowledge Encryption Explained

Traditional cloud storage providers can access your files. ShieldFive is different:

• Your files are encrypted in your browser before upload using military-grade encryption

• Only you can decrypt file contents - we never see your unencrypted files, and shared-link passwords are verified server-side with hashed storage

• Complete privacy - even our employees cannot access your data

This is called "zero-knowledge" because we have zero knowledge of what you store.

How ShieldFive Works

1. Upload: Select a file and set a strong passphrase

2. Encrypt: Your browser encrypts the file using your passphrase

3. Store: The encrypted file is uploaded to secure cloud storage

4. Share: Create secure links with optional restrictions

5. Download: Decrypt files in your browser using your passphrase

Key Features

• Client-Side Encryption: All encryption happens in your browser

• Military-Grade Security: AES-256-GCM encryption with per-file keys and PBKDF2-SHA256 passphrase wrapping

• Zero-Knowledge: We cannot decrypt your file contents and do not store share-link passwords in plaintext

• Secure Sharing: Share with expiration, download limits, and country restrictions

• File Organization: Encrypted folders and searchable file names

• Large Files: Support for files up to 10 TB

• No Account Required for Recipients: Anyone can download shared files

• Individuals: Store personal documents, photos, and backups privately

The Trade-Off: Security vs. Recovery

ShieldFive prioritizes your privacy above all else. This means:

• ✓ Maximum Security: Your files are completely private

• ✓ No Backdoors: No one can access your data without your passphrase

• ✗ No Recovery: Lost passphrases cannot be reset or recovered

This is by design. If we could recover your passphrases, so could hackers or governments. We believe true security means only you have the keys.
