I wrote a few routines for the PC, and they can be found in
/mit/b/c/bcn/kdst/lib/krb/pc.c. I expect there is still a copy in the
master sources, but it may have been removed since I left. Tis file
contains 3 four line procedures.
Since steve did the DES stuff, I am not sure what BIG is for, but if I
recall correctly then, by setting BIG, a more time efficient approach
is taken, but at the cost of space. Unfortunately, on the XT we were
very limited in the maximimum program size.
I am not sure about the byte/bit ordering question, but I think that
there was some difference between the XT and the RT. I may be wrong
though.
