I am working on a custom token using the hook "mymodule_civicrm_tokenValues"  that creates a formatted HTML listing of upcoming events, with a link to register for each event.  I would like to use  {contact.checksum} within the link to register, but I cannot figure out how to calculate the checksum within the code for my hook.

I looked at the "contact" API, but it does not seem to return the checksum. I did not see it in the table civicrm_contact either. (Although there is a field there named "hash" I am not sure how that relates to the checksum)

Any ideas on how to use the checksum inside my hook?

Thanks, that did the trick
