 # NuVotifier
 
-NuVotifier is a Bukkit plugin whose purpose is to be notified (aka *votified*)
-when a vote is made on a Minecraft server top list for the server.  NuVotifier
-creates a *lightweight* server that waits for connections by Minecraft server
-lists and uses a simple protocol to get the required information.  NuVotifier is
-*secure*, and makes sure that all vote notifications are delivered by authentic
-top lists.
+NuVotifier is a secure alternative to using the original Votifier project.
+NuVotifier will work in place of Votifier - any vote listener that supports
+Votifier will also support NuVotifier.
 
-## Why fork Votifier?
+NuVotifier supports many different platforms using the same universal JAR:
 
-Votifier has lagged in activity, has severe security flaws in its protocol, and
-is vulnerable to denial of service attacks.
++ Bukkit / Spigot / Paper >=1.8
++ Sponge 7
++ BungeeCord / Waterfall
++ Velocity
 
-## Is NuVotifier a drop-in replacement for Votifier?
+NuVotifier also adds forwarding and listener test commands not present in the
+original version.
 
-Yes! Except for some minor non-breaking changes (look into the [technical qa
-docs](docs/technical_qa.md) for more info), NuVotifier is 100% compatible with
-the old Votifier with many more features.

-This document outlines some of the technical reasons for a new NuVotifier.
-
-# Why a new protocol?
-
-The old Votifier protocol has three major flaws, which we feel are corrected in the new protocol.
-
-* The data is encrypted (with RSA) but not hashed to verify its integrity. The new protocol utilizes HMAC with SHA256 (but no encryption, given that the data sent is eventually revealed in some form or another).
-* The canonical Votifier protocol is vulnerable to replay attacks.
-* The canonical Votifier is one key for all clients, which is weak. While NuVotifier still supports a default key (for the less paranoid), this ability can be disabled and force per-server keys.
-
-# Is NuVotifier a drop-in replacement for Votifier?
-
-Yes. NuVotifier is compatible with Votifier server lists and Votifier listeners, with some differences:
-
-* The `Vote` object's setters are deprecated.
-* Support for standalone vote listeners (`.class` files) has been removed, as handling `VotifierEvent` is more flexible.
-
-# Protocol Documentation
-
-This documentation is for server lists that wish to add NuVotifier support.
-
-There are two versions of the NuVotifier protocol.
-
-## Handshake
-
-A connection is made to the NuVotifier server by the server list, and immediately NuVotifier will send its version in the following packet:
-
-	"VOTIFIER <version> <challenge>"
-
-The challenge will not be present in version 1.x servers.
-
-## Protocol v2
-
-NuVotifier expects a message composed of `0x733A` (16-bit big-endian integer) and the length of the following JSON message (as a 16-bit big-endian integer) sent plus the message.
-
-The message is JSON-encoded containing the following data:
-
-* `payload` contains the fully encoded vote. It is a JSON message containing the `serviceName` (string), `username` (string), `address` (string, but must be a valid IPv4 or IPv6 address), `timestamp` (a long with the time this vote was taken in _milliseconds_), and `challenge` (from the handshake). It is optional, but recommended to supply a `uuid` field with the player's UUID (with dashes, e.g. `652a2bc4-e8cd-405d-b7b6-98156ee2dc09`).
-* `signature` is a HMAC-SHA256 digest of the payload with a owner-provided key.
-
-A response is given after the vote has been received and parsed, but not yet processed.
-
-For your convenience, the NuVotifier team has provided client libraries in [JavaScript](https://github.com/NuVotifier/votifier2-js), [PHP](https://github.com/NuVotifier/votifier2-php) and [Go](https://github.com/minecrafter/go-votifier). If you are stuck, these libraries may help you.
-
-## Protocol v1 (deprecated)
-
-For better compatibility, NuVotifier supports the old Votifier protocol as well.
-
-NuVotifier expects a 256 byte RSA encrypted block (the public key should be obtained by the NuVotifier user), with the following format:
-
-<table>
-  <tr>
-	<th>Type</th>
-	<th>Value</th>
-  </tr>
-  <tr>
-	<td>string</td>
-	<td>VOTE</td>
-  </tr>
-  <tr>
-	<td>string</td>
-	<td>serviceName</td>
-  </tr>
-  <tr>
-	<td>string</td>
-	<td>username</td>
-  </tr>
-  <tr>
-	<td>string</td>
-	<td>address</td>
-  </tr>
-  <tr>
-	<td>string</td>
-	<td>timeStamp</td>
-  </tr>
-</table>
-
-The first string of value "VOTE" is an opcode check to ensure that RSA was encoded and decoded properly, if this value is wrong then NuVotifier assumes that there was a problem with encryption and drops the connection. `serviceName` is the name of the top list service, `username` is the username (entered by the voter) of the person who voted, `address` is the IP address of the voter, and `timeStamp` is the time stamp of the vote.  Each string is delimited by the newline character `\n` (byte value 10).  The `space` block is the empty space that is left over, **the block must be exactly 256 bytes** regardless of how much information it holds.

-This document outlines how to configure NuVotifier for a variety of different
-configurations. It should be used by server administrators looking to set up
-NuVotifier on their network.
-
-# Key vs Token
-
-This document uses the terms `token` and `key`. These are two separate terms,
-and it is important to understand the differences.
-
-## Key
-
-Keys in terms of NuVotifier refer to the old Votifier style RSA keys. They
-are typically distributed as a pair of files - a public and private key. When
-dealing with RSA keys, you can share your public key with server lists, but make
-sure to keep your private key safe with you. You can find these keys
-auto-generated under `plugins/(Nu)Votifier/rsa/`, where your public key is
-named `public.key`, while your private key is labeled `private.key`. Make sure
-not to separate the two, as they won't work together.
-
-## Token
-
-Tokens in terms of NuVotifier refer to a new short string of characters. This
-string of characters is secret, and should never be exposed to anyone but you or
-server lists which support NuVotifier voting (check with the server list
-first). Tokens are most commonly used internally within a network for use when
-using the proxy vote forwarding method.
-
-# Single Server Configuration (Bukkit / Spigot / Sponge)
-
-You will want to set up your server using these instructions when you only have
-one Minecraft server (Bukkit / Sponge). These are the most trivial installation
-steps.
-
-## Installing the plugin on a server
-
-To install NuVotifier, you should get a copy from one of the following
-locations:
-
-+ [Github](https://github.com/parallelblock/NuVotifier/releases) - Official
-  release location
-+ [SpigotMC](https://www.spigotmc.org/resources/nuvotifier.13449/) - SpigotMC
-  release mirror
-+ [repo.parallelblock.com](https://repo.parallelblock.com/repository/public-raw/nuvotifier/nuvotifier.jar) - ParallelBlock CI 'hot off the presses' releases
-
-The NuVotifier jar should then be placed within the `plugins/` folder of your
-Minecraft server. When you then start your server, NuVotifier will generate
-the necessary configuration and initial keys for you.
-
-## Configuring the plugin
-
-When running in a single server configuration, NuVotifier's default
-configuration works well. The only value which you may need to change is the
-`port` configuration value - this specifies the port on which NuVotifier
-listens to new votes. This port cannot be any port you are already using. For
-example, if Minecraft is running on the default port (25565), you cannot set
-`port` also to 25565. Make sure port is a number from 1-65535.
-
-You can then add your server to server lists using the port you configured while
-also supplying your public key. At this point, you should be able to send a test
-vote to your server!
-
-# Multi-server / Network configuration
-
-You will want to use these instructions when you have more than one server and
-are using a Minecraft proxy (such as BungeeCord, LilyPad, or Velocity).
-
-## Single-Proxy BungeeCord/Velocity Networks
-
-When running a single-proxy network, NuVotifier is able to operate as both
-a vote receiver (emitting events for proxy based vote listeners) as well as
-a vote forwarder. NuVotifier's vote forwarding logic is also advanced enough
-to be used in a wide variety of ways.
-
-### Installing the plugin on the servers
-
-NuVotifier should be installed on each of the servers you wish to process votes
-on, as well as the proxy server. The proxy's NuVotifier server will act as the
-public facing Votifier instance, where as the Minecraft servers will instead
-receive votes forwarded from the proxy's NuVotifier.
-
-Like the single server installation, you can download NuVotifier at any one of
-the following locations:
-
-+ [Github](https://github.com/parallelblock/NuVotifier/releases) - Official
-  release location
-+ [SpigotMC](https://www.spigotmc.org/resources/nuvotifier.13449/) - SpigotMC
-  release mirror
-+ [repo.parallelblock.com](https://repo.parallelblock.com/repository/public-raw/nuvotifier/nuvotifier.jar) - ParallelBlock CI 'hot off the presses' releases
-
-The plugin should then be placed in the `plugins/` directory of the Bungeecord
-server as well as each of the Minecraft servers.
-
-### Vote Forwarding
-
-The following sections describe how vote forwarding works. Vote forwarding is an
-advanced configurable operation, and requires a lot of configuration to get
-correct.
-
-### Plugin messaging based forwarding
-
-This section describes how to set up plugin messaging forwarding. This is
-recommended if you have just one proxy, however this may also work with
-some exceptions in multi-proxy networks.
-
-First off, we should configure each of the Minecraft servers. Open each of the
-servers' NuVotifier configurations. Each one should have `method` under the
-`forwarding` configuration section set to `pluginMessaging`. Under the
-`pluginMessaging` configuration section, `channel` is set to `nuvotifier:votes`.
-Since 1.13, Spigot has decided that channels must now contain a colon. While
-this is a completely senseless change, it is easier to simply conform and change
-the channel name.  This is a safe default (and is protected from injection by a
-hacked Minecraft client), but feel free to change it. If you choose to change
-it, make sure you change it everywhere all around your network!
-
-Since we are receiving forwarded votes through plugin messaging and not through
-network ports, we should set `port` on each of the Minecraft servers to -1. This
-will disable NuVotifier's port, while still allowing it to receive forwarded
-plugin messaging votes. This will only work when using plugin messaging!
-
-Since we have all of that configured, we can now move to the proxy's NuVotifier
-configuration. It is once again located under `plugins/NuVotifier/` directory
-(`config.yml` for BungeeCord, `config.toml` for Velocity). Like the single server,
-`port` should be set to an unbound port. The default `8192` works well, however
-you may have to change it depending on your hosting provider.
-
-Since we are using plugin messaging based forwarding, lets set `method` under
-`forwarding` to `pluginMessaging`. Make sure that `channel` is the same channel
-that you configured your servers to listen to - if you didn't change this value,
-then the default will work.
-
-NuVotifier saves when it can't immediately forward in a user defined cache. In
-almost all installations this should be `file`, however, some installations may
-instead want `none` or `memory`. If you don't know, the `cache` should be set to
-its default, `file`.
-
-By default, NuVotifier will forward the vote to all of the connected Minecraft
-servers (all servers you can get to when typing /server). You can manually
-exclude some of these servers by first uncommenting `excludedServers`, then
-adding the server's name to the `excludedServers` list. After adding, NuVotifier
-will not send any votes to this server. If you only send the vote to the server
-the player joined, these servers are ignored.
-
-NuVotifier can also selectively send the vote to only the server which the
-player has joined. This option can be turned on by setting
-`onlySendToJoinedServer` to true. When this option is on, the vote will attempt
-to go to the server which the player is currently on. If the player is currently
-not on a server (offline), then NuVotifier will then attempt to send the vote to
-the `joinedServerFallback`. If the vote cannot be sent to the
-`joinedServerFallback`, then the vote is saved in the cache until the vote can
-be sent to the `joinedServerFallback` server - note this will not send it to the
-next server the player joins! If you do not want a fallback server and would
-rather the vote be applied when the player next joins, set
-`joinedServerFallback` to `''`. This will cause NuVotifier to save the vote
-until the player joins again.
-
-By default, votes are saved for 10 days in the cache. This time can be increased
-or decreased by changing the `voteTTL` field. This number can be as high or low
-as you want. It is measured in days within the cache.
-
-### Proxy based vote forwarding
-
-In more complex network situations, it may be required to instead use the proxy
-based vote forwarding. This configuration is less flexible and more difficult to
-set up properly - most people should use plugin messaging based forwarding.
-Proxy based forwarding does not support vote caching or advanced forwarding
-configurations. If you cannot use plugin messaging forwarding, then the
-following section will describe how to set up proxy based vote forwarding. If
-you still require advanced forwarding features or more advanced behaviors, it
-may be worthwhile to write your own plugin to perform the proper forwarding logic
-(you will know if you need to do this).
-
-In proxy based vote forwarding, one of your proxy servers acts as the head vote
-receiver. This server will be the one you configure the voting websites to
-vote to. You can set up multiple vote receivers and load balance between them,
-however this configuration has limited benefit and is probably more work than it
-is worth. Instead of communicating through plugin messaging like the plugin
-messaging forwarding strategy, proxy forwarding instead acts like a voting
-website to each of the backend servers and duplicates the vote it receives to
-each of the backend servers it is configured with.
-
-First, we will set up all of the Minecraft servers before setting up the head
-vote receiver. For each of the servers, NuVotifier should be configured to bind
-to an unused port. This port must be valid. If you have multiple Votifiers on
-the same IP/server, make sure that the port which you are using between
-NuVotifier instances are different. Remember the the port number as we will need
-it later to insert into the proxy NuVotifier configuration. In addition to the
-port number, you will also need the default token - this is the string auto
-generated by NuVotifier under the `default` key under `tokens`. Since we are using
-proxy forwarding, change `disable-v1-protocol` to true - we will only be using the
-new NuVotifier protocol within our network (vote receiver -> minecraft server).
-Once all configured, that is all we need to do. The rest of the defaults will work.
-
-Now we will configure the vote receiving NuVotifier proxy server. The port
-should be configured as described many times above, being a unique port. Instead
-of setting `method` to `pluginMessaging` like above, we will set `method` to
-`proxy`. This will tell NuVotifier that we instead want to proxy the votes
-instead of forward them through plugin messaging channels.
-
-The last step is to set up the proxy forwaring settings. Under the `proxy`
-section is a place to enter each server. Create a unique name for each of the
-server's you will be forwarding votes to. The default proxy NuVotifier
-configuration already has two Minecraft servers filled in - Hub and Hub2. You
-should replace these with your own servers - the names of the servers do not
-matter. Under each of these servers, we need to configure `address`, `port`, and
-`token`. `address` is the IP address of the Bukkit/Sponge server. This may be
-`localhost` or `127.0.0.1` if the Minecraft server is on the same physical
-server as the vote receiving NuVotifier server. `port` is the port of the
-Bukkit/Sponge NuVotifier server. `token` is the default token of the
-Bukkit/Sponge NuVotifier server. This can be found within its configuration,
-usually under the `token` section. Once the servers are configured, NuVotifier
-will forward all votes it receives to the servers configured under the `proxy`
-section.
-
-# Debugging NuVotifier
-
-NuVotifier can be difficult to set up in some configurations. If you find you
-don't know what is wrong, you may want to try setting `debug` in each of the
-server's NuVotifier configurations to `true`. This will increase logging within
-your console. 
-
-# Reloading NuVotifier
-
-For Bukkit and Bungee, you may reload NuVotifier through the `/nvreload` command
-in your console only - this command will not work in-game by design. Make sure to
-ensure that it completed correctly before assuming NuVotifier works!
-
-# Default Configurations
-
-If you find you have messed up NuVotifier beyond repair, you can grab a default
-configuration from the following locations (depending on the server it is
-installed on):
-
-+ [Bukkit](https://github.com/parallelblock/NuVotifier/blob/master/bukkit/src/main/resources/bukkitConfig.yml)
-+ [Sponge](https://github.com/parallelblock/NuVotifier/blob/master/sponge/src/main/resources/com/vexsoftware/votifier/sponge/spongeConfig.yml)
-+ [Bungeecord](https://github.com/parallelblock/NuVotifier/blob/master/bungeecord/src/main/resources/bungeeConfig.yml)
-
-You can also regenerate this configuration by deleting the old configuration and
-restarting the server.
