The discovery and application, early on, of frequency analysis to the reading of encrypted communications has, on occasion, altered the course of history. Thus the Zimmermann Telegram triggered the United States' entry into World War I; and Allies reading of Nazi Germany 's ciphers shortened World War II, in some evaluations by as much as two ...
Kahn, David – The Codebreakers (1967) (ISBN 0-684-83130-9) A single-volume source for cryptographic history, at least for events up to the mid-'60s (i.e., to just before DES and the public release of asymmetric key cryptography).

Some 25,000 machines were in use in the mid-1960s.

Duke of Mantua Francesco I Gonzaga is the one who used the earliest example of homophonic Substitution cipher in early 1400s. [ 2 ] [ 3 ] Ibn al-Durayhim : gave detailed descriptions of eight cipher systems that discussed substitution ciphers, leading to the earliest suggestion of a "tableau" of the kind that two centuries later became known as ...
Other services demanded KW-26's and some 14000 units were eventually built, beginning in the early 1960s, for the U.S. Navy, Army, Air Force, Defense Communications Agency, State Department and the CIA. It was provided to U.S. allies as well. When the USS Pueblo was captured by North Korea in 1968, KW-26's were on board. In response, the NSA ...
