Red Code
This was a code book system used in World War I and after. It was so called because the American copies made of it were bound in red covers. It should not be confused with the RED cipher used by the diplomatic corps.
This code consisted of two books. The first contained the code itself; the second contained an additive cipher which was applied to the codes before transmission, with the starting point for the latter being embedded in the transmitted message. A copy of the code book was obtained in a "black bag" operation on the luggage of a Japanese naval attache in 1923; after three years of work Agnes Driscoll was able to break the additive portion of the code.

Famous quotes containing the words red and/or code:
“He is said to have been the last Red Man
In Acton. And the Miller is said to have laughed
If you like to call such a sound a laugh.”
—Robert Frost (1874–1963)
“Hollywood keeps before its child audiences a string of glorified young heroes, everyone of whom is an unhesitating and violent Anarchist. His one answer to everything that annoys him or disparages his country or his parents or his young lady or his personal code of manly conduct is to give the offender a “sock” in the jaw.... My observation leads me to believe that it is not the virtuous people who are good at socking jaws.”
—George Bernard Shaw (1856–1950)
