In 1991 Philip Zimmermann created and freely distributed Pretty Good Privacy (PGP), the most popular email encryption software in the world even all these years later. A PGP-encrypted message masks an email's content using public-key cryptography, allowing only the recipient to read it. The United States Customs Service started a criminal investigation against Zimmermann, citing a possible violation of arms trafficking export controls.
