Cryptanalytic functions
Weboption for 1940's codebreaking. Cryptanalytic functions, they thought, had to be hard wired into a machine. Thus, Monogram's original list did not include a "programmed" computer. Then, OP-20-G's technical leader, Howard Campaigne, decided to send one of his men to see what the University of Pennsylvania was offering at its Moore School's 1946 WebCryptanalysis, as defined at the beginning of this article, is the art of deciphering or even forging communications that are secured by cryptography. History abounds with …
