Secure, Encrypted and Versioned Data Storage Library

Overview

Datasafe is a robust library tailored for developers and enterprises, offering encrypted and versioned data storage. It enhances the security of data-sensitive applications, making it ideal for mission-critical usage.

Key Features

• Enhanced Security: Each user gets unique key encryption keys, reducing the risk of widespread data breaches.
• Full Confidentiality: Offers full or partial file path encryption.
• Ransomware Protection: Versioned storage safeguards against ransomware attacks.
• Secure File Exchange: Features asynchronous inboxes for safe user-to-user file transfers.
• Zero Trust Environments: Ideal as a data encryption layer in critical data processing backends.

Technical Specifications

Datasafe uses AES-GCM (and Chacha-Poly for large files) for encryption, with CMS-envelopes (RFC 5652) for encrypted content wrapping. The library's flexible design allows seamless integration and customization. For more details, refer to our Security Whitepaper.

Highlights

• Configurability: Dagger2 for dependency injection and modular design.
• Storage Compatibility: Tested with Amazon S3, Minio, CEPH, and local filesystems.
• User Privacy: Encrypts both the document and its path in each user's private space.
• Versioning Support: Provides application layer versioning for systems lacking native versioning support.
