PHIL ZIMMERMANN
(Philip R. Zimmermann)
He had developed a mathematical algorithm for a computer encryption that would take years to break even for the most powerful supercomputers. The U. S. Government tried to prevent him from publishing the technique and formula, but he went ahead anyway. They then tried to accuse him of violating an Arms Export Control Act for allowing people in other countries to see it, but there were no legal grounds for indictment. The strong encryption method, PGP, can be used with almost any PC and internet transmission of files.
Philip R. Zimmermann (born 1954) is an American computer scientist and cryptographer. He is the creator of Pretty Good Privacy (PGP), the most widely used email encryption software in the world. He is also known for his work in VoIP encryption protocols, notably ZRTP and Zfone. Zimmermann is co-founder and Chief Scientist of the global encrypted communications firm Silent Circle.
