machine wipe

[travi]

build a script that will wipe sensitive data from a machine quickly

• [ ] lastpass local cache (need to consider app?)
• [ ] lastpass cli cache (~/.lpass) (looks like simply logging out clears this, as hoped) (lpass logout)
• [ ] authy local cache
• [ ] Dropbox synced files
• [ ] Evernote
• [ ] keybase (keybase logout)
  • GPG keys (rm ~/.gnupg/secring.gpg)
• [ ] sensitive info in env vars
  • HOMEBREW_GITHUB_API_TOKEN
• [ ] .bash_history modifications?
• [ ] ssh keys
• [ ] disconnect google account from chrome
• [ ] remove the dotfiles repo and broken symlinks that result?
• [ ] remove creds from netrc (inform me of things i should revoke too)
