Thanks for sharing this! really helpful having a reference implementation when Freshdesk gives you a 24 hour notice that they are deprecating the old implementation 👍

FYI, Freshdesk changed things in 2016 after this gist was posted, this code does not currently work. The plaintext needs to have the key added as the 2nd item (please see my fork and update this gist if possible).
