Since last time:

• The init command initializes a new keys file; I would’ve just made it automatically initiate the process upon any command, but it would’ve made things like the get command a little wonky
• The list command lists all the keys
• The passwd command (not shown) changes the password
• The rm command removes a key
• I have added input validation to most of the commands now, and I found out how to do aliases

I still need to polish some things, specially the consistency of the vocabulary (keys, services, etc.) and the prompts
