Thanks, this change LGTM.

I think we should start trying to move away from any dependencies on
GnuPG 2.0, since it will be retired in ~12 months:

"There are two major flavours of GnuPG:

2.1.17 is the modern version with support for ECC and many other new features,
2.0.30 is the stable version from an often used branch. This branch will
reach end-of-life on 2017-12-31."

I'll look more closely in the next couple days and push if there is no
more feedback.
