I currently try to understand how the adl launch algorithm works. I've found the great tutorial by ht2labs (https://github.com/LearningLocker/xapi-demos) and the corresponding videos (https://vimeo.com/272792141 and https://vimeo.com/272792152). The tutorial shows which data are required by the launch-server to generate the xAPILaunchKey, but not, how it's generated. Could someone explain, how I can generate a valid xAPILaunchKey?
Thanks in advance
