Cryptography laws in different nations

Cryptography laws in different nations

Cryptography is the practice and study of hiding information. There are many different cryptography laws in different nations. Some countries prohibit export of cryptography software and/or encryption algorithms or cryptoanalysis methods. In some countries a license is required to use encryption software, and a few countries ban citizens from encrypting their internet communication. Some countries require decryption keys to be recoverable in case of a police investigation.

France

As of 2011 and since 2004, the law for trust in the digital economy (LCEN)[1] mostly liberalized the use of cryptography. Especially:

  • As long as cryptography is only used for authentication and integrity purposes, it can be freely used. The cryptographic key or the nationality of the entities involved in the transaction do not matter. Typical e-business websites fall under this liberalized regime.
  • For other uses, exportation and importation to or from foreign countries must be either declared (when the other country if a member of the European Union) or requires an explicit authorization (for other countries).
