Remote secrete keeper. i.e., ssh keys, api keys, etc.
A cloud based platform where you have a username/pass and your secrets are encrypted w a private key, so you need the key and username pass to decrypt them.
Basically if you have 8 SSH keys and a 5 API keys you use, something like this would congregate all of it so you just need 1 key for all of it.
Should be written in python3.4. needs a command line tool as well like heroku or docker.
