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).

Extracting the history of a set of files that are spread across multiple subtrees, but are not composed wholly of those subtrees is possible with git, but not always easily grokked. It's not terribly difficult, however; two lines of shell script can get it done. First, use git-filter-branch to extract the history of the files. This, however, may leave you with merge commits that make no changes, because --prune-empty will not prune empty merge commits. A second filter branch, though, can remove those empty merge commits.

git filter-branch -f --prune-empty --index-filter 'git rm --cached --ignore-unmatch $(git ls-files | grep -v "path/to/first/file\|LICENSE")'
git filter-branch -f --prune-empty --parent-filter 'sed -e "s/-p//g" > parents; git show-branch --independent $(cat parents) | sed -e "s/^/ -p /" -e "1 s/^ //" -e "s/^-p$//" | tr "\n" " " | tee -a all-parents; rm -f parents'

# try to create a temporary directory on osx first.
# `mktemp -d` works on OSX and Linux The basename will be random:
TMPDIR=$(mktemp -d)
# `mktemp -d -t FOO` is valid on OSX and uses TMPDIR, but will cause an error on Linux.
# `mktemp -d -t FOO.XXXXXX is valid on both: on Linux will do substitution of the Xs; but on OSX, the Xs are taken literally.
TMPDIR=$(mktemp -d -t ${PREFIX} 2>/dev/null || mktemp -d -t ${PREFIX}.XXXXXX)
# this can be shorted to
TMPDIR=$(mktemp -d "${TMPDIR-:/tmp/}$PREFIX.XXXXXX")
