I'm having trouble pinpointing the origin of the initial hash values
for SHA 224 and, for that matter, 128. These values are defined as hex
representations of cube roots of primes for sha-1 of lengths 256, 384
and 512, but I can't find where they were obtained for the shorter
lengths.

ng to generate a power of "a" that is
congruent to 1.
The "n" vs "n-1" distinction appears only when discussing if "x^2 - 1
= 0 (mod n)". This is why M-R fails for "n=2".
