In your script.py, you can now use symmetric encryption to encrypt your data. The encryption is performed with an instance of cryptography.fernet.Fernet, using a safe, user-specific unique key generated by mortimer (v0.4.4+).
Encryption: Encrypt data of types str, int, and float via alfred.Experiment.encrypt(). The method will return an encrypted version of your data, converted to string.
Decryption: Decrypt data of types str or bytes via alfred.Experiment.decrypt(). The method will return a decrypted version of your data, converted to string.
NOTE that the saving agent will automatically save all data collected by elements (after the on_hiding() method is executed). You will need to encrypt data before they are saved in order to secure your data in the database.
For offline testing, the Fernet instance will be initialized with the key OnLhaIRmTULrMCkimb0CrBASBc293EYCfdNuUvIohV8=. IMPORTANT: This key is public. Encrypted data in local (e.g., offline) experiments is not safe. This functionality is provided exclusively for testing your experiment before uploading to mortimer and running.
Smaller changes and Bugfixes
Pages now have a getter method for their experiment, i.e. you can access the experiment via Page.experiment, if the page has been added to an experiment instance at the time the method is called.
Fixed the display of experimenter messages (e.g. a message that informs the participant about a minimum display time, if he or she tries to move to the next page too early)
