Slight correction: client-side encryption *is* encryption-at-rest, it is simply performed on the client side.  We currently do not support server-side encryption.  With client-side encryption, keys are managed by the application and kept separate from the storage, ensuring that any electronic intrusion of the storage or theft of physical storage hardware does not grant access to data.  Our Atmos client provides client-side envelop encryption today and the same standard is coming to our new ECS object client (S3) as well.
I could not find a clear answer to this question. I am looking for information on if data-at-rest encryption is a feature of ViPR/ECS. I.e., is there server side object data encryption performed when objects are stored in ViPR/ECS?  Thanks.
Are objects stored in ViPR/ECS encrypted?
