+# hash_tester.py
+# --------------
+# This program sends several commands to the coretest_hashed subsystem
+# in order to verify the SHA-1, SHA-256 and SHA-512/x hash function
+# cores. The program will use the built in hash implementations in
+# Python to do functional comparison and validation.
+#
+# Note: This program requires the PySerial module.
+# http://pyserial.sourceforge.net/
+#
+# The single and dual block test cases are taken from the
+# NIST KAT document:
+# http://csrc.nist.gov/groups/ST/toolkit/documents/Examples/SHA_All.pdf
