Hi Grahame,

You might want to have a look at:
  http://httpwg.org/http-extensions/draft-ietf-httpbis-encryption-encoding.html
... along with the implementation list at:
  https://github.com/httpwg/wiki/wiki/EncryptedContentEncoding

Cheers,

P.S. Anticipating people's questions as "stupid" doesn't help the level of discourse here. Please refrain from doing so. Thanks.

This discussion isn't really about functionality but about the ability of large government backbone administrators to tick the box that they'll have the control they need, while being able to tick the box that they've protected the patient's privacy and the healthcare provider's need for reliability
