What is AES-256?

AES-256 (Advanced Encryption Standard with a 256-bit key) is a symmetric encryption algorithm recognized as one of the most secure encryption methods available. It is widely used for securing sensitive data, including files, communications, and authentication processes.

How AES-256 Works

AES-256 encrypts data using a 256-bit key length, making it exponentially more secure than shorter key lengths such as AES-128 or AES-192. The encryption process involves multiple rounds of substitution, permutation, and mixing, ensuring that the original data is transformed into an unreadable format without the correct decryption key.

Why AES-256 Matters for CFS

Cirrus File Server (CFS) employs AES-256 encryption to protect stored and transmitted files, ensuring that customer data remains secure against unauthorized access. This level of encryption is compliant with security standards such as FIPS 140-2, HIPAA, and GDPR, making it suitable for businesses handling confidential records.

Key Benefits of AES-256

Strongest Symmetric Encryption
Used by governments, financial institutions, and enterprises worldwide.
Highly Resistant to Brute-Force Attacks
A 256-bit key provides an astronomical number of possible key combinations, making decryption infeasible without authorization.
Performance & Security Balance
AES-256 offers a robust security model without compromising performance when implemented efficiently.
Compliance-Friendly
Meets stringent data protection regulations and standards.

Use Cases in CFS

  • Secure File Storage – Ensuring that digitized records and structured data remain protected.

  • End-to-End Encryption – Safeguarding files during transit and at rest.

  • AI-Powered Search with Privacy – Allowing metadata extraction and AI-driven indexing while maintaining encryption integrity.

CFS leverages AES-256 encryption as a fundamental security measure, ensuring that businesses can confidently store and manage their sensitive digital and digitized records.
