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

> CoreWeave AI Object Storage now supports server-side encryption with customer keys (SSE-C)

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](/products/storage/object-storage/buckets/server-side-encryption/about-sse-c) and [SSE-C how-to guide](/products/storage/object-storage/buckets/server-side-encryption/use-sse-c).
