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:
“It was almost two years ago, while awaiting the imminent birth of my second child, that I decided to start working part-time. This would have been unthinkable to me when I was younger. At twenty-five I should have worn a big red A on my chest; it would have stood for ambition, an ambition so brazen and burning that it would have reduced Hester Prynne’s transgression to pale pink.”
—Anna Quindlen (20th century)
“Acknowledge your will and speak to us all, “This alone is what I will to be!” Hang your own penal code up above you: we want to be its enforcers!”
—Friedrich Nietzsche (1844–1900)
