Code-breaking US history

Before hackers, there were code breakers.

During World War II and continuing into the Cold War, government agents and private-sector technologists worked together to crack enemy ciphers, often building new machines to aid the effort.

Today many Americans associate the National Security Agency with efforts to hide the government's top-secret work from the general population. But that's not the case at the NSA's National Cryptologic Museum, located in Annapolis Junction, Maryland. It houses many examples of the country's top-secret code-breaking history, from spy plane wreckage to computers that were truly ahead of their time.

Here's a sampling of the spy secrets now on display from the government's most secretive agency.
