August 4, 2025 - CoreWeave AI Object Storage SSE-C support

CoreWeave AI Object Storage now supports server-side encryption with customer keys (SSE-C). SSE-C allows you to encrypt objects using AES-256 encryption keys that you provide and manage, giving you complete control over your encryption keys while CoreWeave handles the encryption and decryption process transparently.

Use cases

SSE-C is ideal for scenarios where you need:

Use case	Description
Regulatory compliance	Meet requirements for customer-managed encryption keys
Enhanced security	Maintain complete control over your encryption keys
Data sovereignty	Ensure encryption keys never leave your control
Multi-tenant environments	Use different keys for different customers or projects

Implementation

SSE-C works with standard S3-compatible tools and libraries, and supports using different keys for different objects or requests. For detailed implementation guides and examples, see the SSE-C concept guide and SSE-C how-to guide.
