Kalvados is an Apple receipt generator for testing.
You can use kalvados to get base64 encoded bynary receipt data from JSON.
JSON format that kalvados can parse is like this.

}You can run kalvados server on Google App Engine.
cd appengine/app
make deploy
Before deploy, you should put your private key file as key.pem and certificate file as cert.pem under appengine/app directory. Or you can set your private key and certificate in app.yaml like this.
In app.yaml:
env_variables:
# It seems GAE/Go could not handle environment variables
# that has return code.So use ">-" to replace return code
# with white space
CERTIFICATE: >-
