Command Line Interface

There is a command line interface for baking and unbaking assertion data.

To bake a badge, identify the existing BadgeClass image with the input_filename and desired baked Assertion image filename to be created as well as the data to be baked into the image.

bakery bake [input_filename] [output_filename] --data='{"data": "data"}'

To extract Open Badges data from an image, use the unbake command.

bakery unbake [input_filename]

Output_filename is optional if you want the baked data to be written to a file.

bakery unbake [input_filename] [output_filename]

Python Interface

The bake and unbake functions are available when installed as a python module

To bake a badge, pass in an open file as input_file and the string of the badge data you wish to bake into the image. Result is an open TemporaryFile that contains the data.

from openbadges_bakery import bake
output_file = bake(input_file, assertion_json_string)

To unbake a badge, pass in an open file as input_file:

from openbadges_bakery import unbake
output_file = unbake(input_file)
