Steam Community ID to Steam ID

Steam ID to Steam Community ID

This turns any Steam ID into a Steam Community ID using a simple algorithm.

Example is included in the script.

Just 4 note:

76561197960265728 = 2^32 + 2^52 + 2^56

Not in UDF. But it is a shorter form. You need the Math UDF from the forum here.

;STEAM_0:0:1683585
;76561197960265728
;~ Friend ID's with even numbers are the 1 auth server.
;~ Friend ID's with odd numbers are the 0 auth server. 
#include <Math.au3>
$Id = 22741331
If _IsEven($Id) Then
    $auth = 1
Else
    $auth = 0
EndIf
;~ $auth = 0
InputBox("", "", "http://steamcommunity.com/profiles/" & $Id*2+76561197960265728+$auth, "", 500, 120)

Only 1 way, but you can just reverse it for the other way.

Thanks ZokNy, that explains it.

Hm, this won't work everytime, because ther're steam IDs looking like this too:

STEAM_1:1:1234567

STEAM_0:1:1234567

And you can't calculate the first two numbers.

I can calculate the second number. Updated UDF.

STEAM_X:0:1234567 or STEAM_X:1:1234567 now work. The first number can not be calculated from the community id.

A steamid works like this...

STEAM_X:Y:Z

• X represents the "Universe" the steam account belongs to (which is identified by an unsigned 8-bit value)
• Y represents the type of account and is represented as an unsigned 4-bit value
• Z is the ID number for the account (the "account number") identified by a 32-bit unsigned value. Z is not unique.

The remaining 20 bits are used to represent the 'instance' of this account and only applies for a special type of account called a 'Multiseat' account (an account for which many users can log into at the same time, for instance at cybercafes).

Universes Available for Steam Accounts

There are 8 universes of Steam accounts.

Number Type

0 Individual / Unspecified

1 Public

2 Beta

3 Internal

4 Dev

5 RC

Types of Steam Accounts

There are ten known account types for a Steam account, of which only 4 can be created today.

Number Type Can Be Used?

0 Invalid / Unspecified Yes

1 Individual Yes

2 Multiseat Yes

3 GameServer Yes

4 AnonGameServer Yes

5 Pending No

6 ContentServer Unknown

7 Clan Unknown

8 Chat Unknown

9 P2P SuperSeeder No

The conversion is a bit obscure but better than nothing. Valve hasn't sorted this out very well themselves either.

Says both way does work as I implemented it.

[bluerein]

[jvanegmond]

What about it? It doesn't look very interesting. Depends on what you want to do with it, really..

[bluerein]

well , I would'nt mind being able to login and fetch user info like vac status etc , account type etc
