Summary

It is a crime to knowingly give, show, publish, or use classified signals‑intelligence or cryptography information in a way that harms the United States or helps a foreign government. That covers secret details about codes or ciphers, the design or use of machines or devices for signals or cryptographic work, the country’s communications‑intelligence activities, and information obtained by intercepting a foreign government’s communications. A person who does this can be fined under federal law, put in prison for up to 10 years, or both. A congressional committee may still receive the information if it is properly and legally requested. The law defines a few key words in simple ways: "classified information" means material officially marked for limited sharing because of national security; "code, cipher, or cryptographic system" means any method, device, or process for hiding message meanings; "foreign government" means anyone acting for a government or pretending to act for one in another country; "communication intelligence" means methods of intercepting messages and getting information not meant for the recipient; and "unauthorized person" means anyone not allowed by the President or an authorized agency head to get this information. A person convicted must forfeit any money made from the crime and any property used to commit it; the court must order the forfeiture, federal forfeiture rules generally apply, and leftover funds after costs go to the Crime Victims Fund. "State" includes the 50 states, DC, Puerto Rico, and U.S. territories.
