CoreWeave AI Object Storage now supports server-side encryption with customer keys (SSE-C)
Update Storage CoreWeave AI Object Storage now supports server-side encryption with customer keys (SSE-C), providing enhanced data security and control for your stored objects. SSE-C allows you to encrypt your data using encryption keys that you provide and manage, giving you complete control over your encryption keys while CoreWeave handles the encryption and decryption process.
Overview
CoreWeave AI Object Storage now supports server-side encryption with customer keys (SSE-C), providing enhanced data security and control for your stored objects. SSE-C allows you to encrypt your data using encryption keys that you provide and manage, giving you complete control over your encryption keys while CoreWeave handles the encryption and decryption process.
Key features
| Feature | Description |
|---|---|
| Customer-managed keys | Generate, store, and manage your encryption keys outside of CoreWeave |
| AES-256 encryption | Industry-standard encryption algorithm with 256-bit keys |
| S3-compatible | Works with standard S3-compatible tools and libraries |
| Per-request encryption | Use different keys for different objects or requests |
| Automatic encryption/decryption | 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
For detailed implementation guides and examples, see the SSE-C concept guide and SSE-C how-to guide.
