�/6R�c@sTdZddlZddlZddlmZmZmZGdd�de�Z	dS(uStore and retrieve wheel signing / verifying keys.

Given a scope (a package name, + meaning "all packages", or - meaning 
"no packages"), return a list of verifying keys that are trusted for that 
scope.

Given a package name, return a list of (scope, key) suggested keys to sign
that package (only the verifying keys; the private signing key is stored
elsewhere).

Keys here are represented as urlsafe_b64encoded strings with no padding.

Tentative command line interface:

# list trusts
wheel trust
# trust a particular key for all
wheel trust + key
# trust key for beaglevote
wheel trust beaglevote key
# stop trusting a key for all
wheel untrust + key

# generate a key pair
wheel keygen

# import a signing key from a file
wheel import keyfile

# export a signing key
wheel export key
