+There are two sets of SHA example files:
+
+1. The response (.rsp) files contain properly formatted CAVS response files.
+
+2. The intermediate value (.txt) files for the Monte Carlo tests contain
+   values for the inner loop as shown in the pseudocode in Figure 1 on page 9
+   of the SHA Validation System.  The inner loop variable 'i' ranges in value
+   from 3 to 1002.  The intermediate values for the first five iterations of
+   the inner loop therefore correspond to 'i' values of 3 to 7. The message (M)
+   and the message digest (MDi) for each of these i are printed out, indented
+   by one tab space.  The final message digest (MD), not indented, is the last
+   value printed for each count.
