About PredictionBook helper

This extension provides an interface for PredictionBook.com that performs automatic client-side encryption of prediction titles before they are stored on the server, providing added security in the event of a server compromise. Prediction titles are automatically decrypted before being displayed to the user. Strong encryption is provided by the AES-GCM algorithm, with a user-defined password.
