Convenient way to hash a plaintext password. The resulting

hash is written to stdout as a base64 string.

--plaintext, when omitted, will be read from stdin. If

Caddy is attached to a controlling tty, the plaintext will

not be echoed.

--algorithm currently only supports 'bcrypt', and is the default.
