Cryptography (Civ6)

Cryptography is a Diplomatic Policy Card in Civilization VI.
== Strategy ==
Cryptography serves dual purposes: it protects your cities from enemy Spies and enables your Spies to carry out offensive missions more successfully. It's a good go-to policy in the late game, especially if you have a substantial scientific, cultural, or economic advantage over your opponents and they're trying to use their Spies to close the gap.
