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:
“Who dreamed that beauty passes like a dream?
For these red lips, with all their mournful pride,
Mournful that no new wonder may betide,
Troy passed away in one high funeral gleam,
And Usna’s children died.”
—William Butler Yeats (1865–1939)
“... the self respect of individuals ought to make them demand of their leaders conformity with an agreed-upon code of ethics and moral conduct.”
