Release: Amazon S3 on 2014-06-12

Server-side encryption with customer-provided encryption keys

Amazon S3 now supports server-side encryption with customer-provided encryption keys (SSE-C). Server-side encryption enables you to request Amazon S3 to encrypt your data at rest. When using SSE-C, Amazon S3 encrypts your objects with the custom encryption keys that you provide. Since Amazon S3 performs the encryption for you, you get the benefits of using your own encryption keys without the cost of writing or executing your own encryption code. For more information, go to the Server-Side Encryption (Using Customer-Provided Encryption Keys) topic in the Amazon S3 Developer Guide.
