This directory contains a public/private keypair generated just for this repository.
The public key is a deploy key which has been added to the GitHub repo for push access.
The private key is encrypted using travis encrypt-file and then committed to this repo.
The decrypt commands are in .travis.yml.
To regenerate a key:
ssh-keygen -b 4096 -f .travis/govuk_prototype_kit # Make a new keypair
travis encrypt-file .travis/govuk_prototype_kit # Encrypt the private key
mv govuk_prototype_kit.enc .travis/ # Move the private key to the right place
rm .travis/govuk_prototype_kit # Remove the unencrypted private key
