Once you are confident enough testing is performed, use Option 1 to create a new (final) signature with your main key and distribute it. Distribute the addon with this key to both users and server admins. Instead, create a new key, called something like myKeyBeta15, and use this key to sign it. In case you want the addon to pass some more testing before you are sure you can sign it, do not sign it with your main key. Pass your key to BinPBO so that your addons are signed while packing. Option 2: Sign your addons while packing them Include this signature together with your distributed addon files. This example creates a signature file: ''. Use DSSignFile to create a signature for the addon pbo which is already in use. Option 1: Sign your addons which are already packed (This is also important from admins point of view - installing a new addon signed with a key which is already trusted is a straightforward operation, while installing a new key is a step which should be considered much less frequent, and requires more attention from side of the admin). You do not need a new key for each addon - in normal circumstances you should be using the same key over and over for multiple addons. It is only used by the server and not by the client. You can include the key with your distributed addon or separately, since it has no dependency on the actual addon.

Of course, server admins are free to communicate their experiences with various signatures, or create a publicly accessible black lists of signatures which they think are no longer trustworthy, like when they know they were compromised because the private key has been leaked. There is no central authority deciding which signatures are trustworthy and which not. Replaces obsolete v1 (since ARMA 2 version 1.10 and ARMA 2: OA version 1.59), v1 was deprecated as insecure Usually (vanilla installation) there's only Bohemia Interactive's signature, called bi.bikey, in this directory. Server admin can decide which addon makers he considers trustworthy by placing their public keys in the 'keys' directory. If a server admin decides addon signatures should be verified, he should add the following line to the server.cfg file:

This can be done using Arma: Mod Folders or by using some 3rd party addon management utilities.Д¬ontrolling addon signature verification on the server If player wants to use unsigned addons when playing single player or when playing on other servers not testing for this, he needs to make sure such addons are not loaded before connecting to the checked server.

use addons which are signed, but not by an accepted signature.

Player cannot do any of the following if he wants to pass signature verification: Any player not complying to this is detected, and based on server configuration a message in this sense may be displayed, or he may be kicked out, or another action defined by the server admin may be done. Player connecting to a checked server is allowed to have present only addons which are signed by accepted signature.

Accepted signature: one of the signatures defined by the server as trusted.

Unchecked server: a server with signature verification off.

Checked server: a server with signature verification on.

They are based on strong cryptographic principles (private/public key pairs), therefore hacking around them is very hard.ДЄddon is signed by its creator using a private key, while the public key is used by the game to verify that the addon has not been modified.

They are used to detect data files modified by anyone else but the addon creator.
