Get this to a release state
- Fixed CommandCompleter so tab completion works again.
- Fixed most of the mkpasswd command, it's also now more secure as it
only shows in your SSH session and not other's consoles.
- Removed some now unused code.

d38c75dd9e SSH on bungee now works.
Had to rewrite the mkpasswd command and how the console was handled
in the SSH session as many areas didn't use CRLF compared to Spigot
which seems to work better. The config had to be done manually for
the plugin since BungeeCord doesn't handle plugin configs as conveniently.

Removed the test server I accidentally added to the git repo.

586910a75c PHEW! A lot of the conversion to bungeecord is complete, there's only one more class to complete, but I suspect there will be quite a few bugs. 2019-10-08 15:36:48 -05:00

Setting Up Public Key Authentication
====================================
Setting up public key authentication with SSH requires first generating a public and private key pair and then installing just the public key on your Spigot server. This plugin supports all modern SSH key algoritms as OpenSSH. You can paste as many public keys from the methods below into each user's authorization file if they have multiple private keys. You can read [this guide from ssh.com](https://www.ssh.com/ssh/keygen/) if you want a better explanation on different key files.
