How to Validate an Invitation Code in Python
The invitation code for each of your users is simply a SHA1 hex digest of your secret invitation decoder key followed by their e-mail address.
Given a secret invitation decoder key of d1696aeb245fa90380a192a41730f07464c906ea and a user email address of email@example.com (which must be all lowercase), here's how to calculate this user's invitation code in Ruby:
import hashlib <br>invitation_code = hashlib.sha1("firstname.lastname@example.org").hexdigest()
Your project's secret invitation decoder key can be found within your account on the Beta Management Settings page available via the Settings -> Project Settings menu in the upper-right corner of the page.
Remember, if you have enabled the use of short invitation codes in Prefinery ( which are enabled by default), you only need to validate the first 10 characters of the calculated invitation code.
