The "Trust Gap" in Modern File Sharing
Most cloud providers claim your data is "encrypted at rest." What they don't mention is that they manage the encryption keys. If a provider can reset your password or "scan for malware," they have the technical ability to read every file you've ever uploaded.
| Security Feature | Standard Cloud (Dropbox/Google) | Synclyz Zero-Knowledge |
|---|---|---|
| Encryption Method | Server-Side (After upload) | Client-Side (Before upload) |
| Key Ownership | Provider Managed | User Managed |
| Malware/AI Scanning | YES (Files are read) | NO (Files are unreadable) |
| Employee Access | Technically Possible | Mathematically Impossible |
| Legal Subpoena Safe | No (Readable files handed over) | Yes (Only ciphertext handed over) |
How Zero-Knowledge Sharing Works
Synclyz leverages the Web Crypto API to perform heavy-duty cryptographic operations directly in your browser. This ensures that no unencrypted data ever touches the network.
AES-256-GCM
We use the Galois/Counter Mode of the Advanced Encryption Standard, providing both data confidentiality and authenticity in one high-performance step.
URL Fragment Keys
Sharing keys are stored in the URL fragment (the part after the #). Browsers never transmit this to the server, keeping your share-links truly private.
PBKDF2 Derivation
Your master keys are derived using thousands of iterations of the Password-Based Key Derivation Function 2 to protect against brute-force attacks.
No Metadata Leaks
We go beyond file content. Synclyz works to minimize metadata footprints, ensuring your sharing habits remain as private as your files.
When Privacy Is Not Optional
Encrypted file sharing isn't just for whistleblowers; it is a fundamental requirement for modern professional integrity.
High-Value Intellectual Property
Creative agencies and engineers use Synclyz to transfer source code, raw designs, and unreleased blueprints that are the lifeblood of their business.
Sensitive Legal Documents
Attorney-client privilege is only as strong as the medium used for transfer. Zero-knowledge ensures compliance with ethical obligations.
Financial Compliance
Accountants and CFOs leverage Synclyz to move tax records and payroll data, eliminating the risk of provider-side data breaches.
Secure Journalistic Sources
Protecting sources requires end-to-end encryption that guards against both corporate surveillance and government overreach.
The Future of File Sharing is Private.
