This script will test a Shotgun site for SSL compatibility.

Paste the contents into a script editor to run (for example within Maya or Nuke) or run the script from the command line like:

python ./shotgun_ssl_check.py

An example of successful output is:

=================================================
Windows-post2008Server-6.2.9200
Python %s 2.7.3 (default, Jul 29 2013, 17:54:54) [MSC v.1600 64 bit (AMD64)]
OpenSSL 1.0.0a 1 Jun 2010
=================================================
- sha2check.shotgunstudio.com: TEST PASSED

An example of failed output is:

Hey Rob,

Is there a version of this script for testing through a proxy?

Cheers
