Well, poo. Sorry I missed it.

We landed support for image signing in SDK:


so I don't think it would be an issue to also land support for 
encryption. I'd like to have support for signing so that people using 
SDK could do signing. However, like OSC, SDK doesn't use oslo deps, 
largely for the reason you mention - they're written for server side and 
vastly complicate the client-side story. SDK will not grow a dependency 
on os-brick, even an optional one.

How about if we put the encryption routines in SDK, then expose them to 
the server-side components via SDK?

is where we define the similar parameters for server create in SDK. As 
we're making the new OSC params, if we can align naming and usage, that 
would likely lead to future joy - unless we can't, in which case it's fine.
