Pritunl Zero uses a SHA512 HMAC instead of the SHA256 HMAC used in Pritunl. The validation code is in [**pritunl/pritunl-zero/signature/signature.go**](https://github.com/pritunl/pritunl-zero/blob/master/signature/signature.go#L94). The error shown is a unicode error possibly because of the Python 3 detection line `if sys.version_info[0] < 3:` not working correctly. If it is Python 3 the Python 2 if case should be removed.
