This article is missing information about non-CoCom, like Chinese licensing (商用密码产品出口许可).(May 2020)
The export of cryptography is the transfer from one country to another of devices and technology related to cryptography.
In the early days of the Cold War, the United States and its allies developed an elaborate series of export control regulations designed to prevent a wide range of Western technology from falling into the hands of others, particularly the Eastern bloc. All export of technology classed as 'critical' required a license. CoCom was organized to coordinate Western export controls.
