What does hashing or fingerprinting a plugin mean?
Hashing is adding a layer of security to your plugin. It means that if anyone modifies your plugin it will be rendered unusable unless it is re-hashed using your credentials. A fingerprint uniquely identifies the plugin. A fingerprint is a SHA-256 hash and is tied to a key. You can create a fingerprint by running the acchash tool distributed as part of the AIM SDK. Fingerprints are optional for plugins.
