VENONA project

The VENONA project was a long-running and highly secret collaboration between United States intelligence agencies and the United Kingdom's MI5 that involved the cryptanalysis of messages sent by several Soviet intelligence agencies. There were known to be at least 13 code words for this effort used by the US and UK. VENONA was the last code word for the project.
