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 caseDescription
Regulatory complianceMeet requirements for customer-managed encryption keys
Enhanced securityMaintain complete control over your encryption keys
Data sovereigntyEnsure encryption keys never leave your control
Multi-tenant environmentsUse 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.
