@andrewgaul server side encryption interacts not at all with user-provided encryption keys. The user provided encryption keys feature is only implemented in the AWS client SDKs. It could even be combined with each other. User provided encryption keys could even be a blobstore-generic feature which works for all blobstores (which treat data as opaque).
In short it works by encrypting it locally and adding one piece of user metadata (the checksum of the key) to identify the key later. --- Reply to this email directly or view it on GitHub: https://github.com/jclouds/jclouds/pull/344#issuecomment-77545099
