# CASA ATS Keystore Setup Script.
#
# An ATS signs tokens and communicates with clients over
# SSL. This scrip sets up the necessary key-pairs and
# certificates for the ATS to perform these functions.
#
# For token signing purposes, this scrip creates a self
# signed certificate that it then exports. At this time it
# is sufficient to utilize self signed certificates because
# they are meant to be consumed by entities of the local
# box.
