Hi, I'd like you to take a look at this patch for potential SecurityImpact. https://review.openstack.org/123220 Log: commit 43af26fe405ff2d4bca5fecdd6d3485db342a789 Author: Christian Cachin <cca at zurich.ibm.com> Date: Wed Oct 8 13:41:40 2014 +0200 Draft specification for storage encryption in Swift This draft serves for agreeing on the security goals of encryption support in Swift, its design and important implementation choices. This spec revises the "spec for on-disk encryption" here https://review.openstack.org/#/c/123220/ and extends the security model and the design. It also takes into account some of the discussion there. For relevant background, see also the earlier blueprint https://blueprints.launchpad.net/swift/+spec/swift-enc-proxy The change-id points to relevant prior post of design for on-disk encryption.
