Lecture 6: We finished mode of operations: CTR and CFB. We also started mathematics
that we need for public-key cryptography. We covered arithmetic mode n and algorithm
for computing GCDs.
Date: Th, 02/02/2006.
Reading assignment: Read the output feedback mode (mode). Get familiar with the
GCD algorithm.
