Re: RGW automation encryption - still testing only?

Hi Casey,

great news to hear about "SSE-S3 almost implemented" :-)

One question about that - will the implementation have one key per bucket, or one key per individual object?

Amazon (as per the public available docs) is using one unique key per object - and encrypts the key on top of this with a per bucket or master key that regularly rotates.

hi David,

that method of encryption based on rgw_crypt_default_encryption_key
will never be officially supported. however, support for SSE-S3
encryption [1] is nearly complete in [2] (cc Marcus), and we hope to
include that in the quincy release - and if not, we'll backport it to
quincy in an early point release

can SSE-S3 with PutBucketEncryption satisfy your use case?

Is RGW encryption for all objects at rest still testing only, and if not,
which version is it considered stable in?:
