YubiKey 4 series GPG and SSH setup guide

Written for fairly adept technical users, preferably of Debian GNU/Linux, not for absolute beginners.

You'll probably be working with a single smartcard, so you'll want only one primary key (1. Sign & Certify) and two associated subkeys (2. Encrypt, 3. Authenticate). I've published a Bash function which automates this slightly special key generation process.

# Assumptions:
#
# * After the merge is complete, the directory should exist in the target repository and not exist in the source
#   repository. In other words, this is a move, not a cross-reference: we never want to be able to push commits
#   back to the source repository, or merge further changes from the source repository. If you want to do that
#   instead, a subtree merge is what you're looking for.
#
# * The directory doesn't exist in the target repository yet.
#
# In this example, we're moving the "/openstack-swift/" directory from jclouds/jclouds-labs-openstack to

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style
