For dev. UniqueIdUtils v1.1.0

64FF00 submitted a new plugin:

UniqueIdUtils - A small collection of UUID related commands for developers

Read more about this plugin...

So this UUID is now implemented for pocketmine? So maybe this will allow to control (ban and mute people really XD) people without being IP dependent?

what is the UUID for?
and we can use uuid to ban ppl?

UUID, as far as I know, is an unique ID given to all players and it is unchangeable. That is how the ban system works in Minecraft 1.8. So if this is implemented into MCPE, this would be very, very useful.

well i will find/try to find a way to bypass it

here is result
http://prntscr.com/7euxx4
well the UUID is IP+Cleint ID(^1)+Name
^1=located somewhere in side mcpe file
i think it is Minecraft PE/document/games/com.mojang/minecraftpe/clientid.txt
it can be simply changed by using a file manager
and mcpe use that client id to store inv on a local server

PHP:

$this->uuid = Utils::dataToUUID($this->randomClientId, $this->iusername, $this->getAddress());

UUID (Unique User IDentifier) is processed from an md5-digested string generated using randomClientId (clientId.txt in the minecraftpe directory), case-insensitive username and IP address.

The first one, randomClientId, as mentioned by @Thunder33345, can be easily changed if you know how to.
The second one, username, can more easily be changed, obviously.
The third one, IP address, may change every time the client connects to another network (between Wi-Fi, 3G/4G data and VPNs) or the network connects to the internet provider again (i.e. router reboot for some people with dynamic IPs).

When a player is normally transferred using FastTransfer, (without any mods or network settings changes of course) the player should have the same UUID because none of the above three should change. But when one of the above three changes, md5 will digest the data into a totally different and unrecognizable string, so it is not a good idea to ban using UUID.

Comparison:

UUID bans: disallow joining only if IP address and username and clientId are ALL the same.
Name/IP bans: disallow whenever IP address or username or clientId is the same.

is there a client id ban?
i know client id is easy to change if you know what you are doing
but it can ban some no jailbreaker/rooter (they cant change it)

Damn..... I hate how people can change their username and IP easily so it is very easy to evade ban.
@Thunder33345 Hey, hey, HEY! Dont you ever try to evade ban.

Yes, make a plugin for that Although client ID is easy to change, without any rooting needed (for Android at least, afaik).

well i enjoy breaking things
exploiting stuff on PM server form economy glitch to more bigger things
and against the system or banning was part of it

well in IOS without jailbreak it is not easy to change too
this help banning simple spammer/griefer

For simple ones, just ban their IP. It is technically impossible to ban someone if he has infinite IPs.

i have infinity* ips not subnet
my ip is dynamic and it changes everyday
*it will have to wait like 15m-30min

Infinity is noun. Infinite is adjective.
In a subnet of a.b.c.*, you can get a maximum of 256 IPs in theory.
In a subnet of a.b.*.*, you can get a maximum of 65536 IPs in theory.
Even if you have so-called infinite IPs, it is still limited to 256^4 IPs, although banning all them will mean banning everyone.

It will definitely be more secure.

well what ever you win
still you will ban legit user

Lol if u have android you can change your uuid in the games/com.mojang/minecraftpe folder lol

That's called client ID ($player->randomClientId) not UUID.

So we can use Name/IP bans Ban their IP/Name AND clientID
