Autocrypt header field

[[[ To any NSA and FBI agents reading my email: please consider    ]]]

[[[ foreign or domestic, requires you to follow Snowden's example. ]]]

I just got an email with an Autocrypt header field.
Rmail doesn't know how to make use of that.
Would someone like to implement that, for Rmail and Gnus?
Or at least start by reporting what the contents mean,
what formats, etc?
