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 ...
1989 – Quantum cryptography experimentally demonstrated in a proof-of-the-principle experiment by Charles Bennett et al. 1991 – Phil Zimmermann releases the public key encryption program PGP along with its source code, which quickly appears on the Internet. 1994 – Bruce Schneier's Applied Cryptography is published.
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). The added chapter on more recent developments (in the most recent edition) is quite thin.

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 ...
By the 1960s, however, financial organizations were beginning to require strong commercial encryption on the rapidly growing field of wired money transfer. The U.S. Government's introduction of the Data Encryption Standard in 1975 meant that commercial uses of high quality encryption would become common, and serious problems of export control ...
In 1955, the AFSAM-7 was renamed TSEC/KL-7, following the new standard crypto nomenclature. It was the most widely used crypto machine in the US armed forces until the mid-1960s and was the first machine capable of supporting large networks that was considered secure against known plaintext attack. Some 25,000 machines were in use in the mid-1960s.
