Bad things do happen to good code. So learned Phil Zimmermann, author of Pretty Good Privacy (PGP), which in the early 1990s became the de facto standard for cryptology development on the Internet, according to analysts and user groups.
While working with human rights advocates in 1991, Zimmermann released his powerful encryption, signing and authentication freeware, which did away with the need for third-party key authorities to issue and manage the keys that lock and unlock data.
In fact, the mathematical encryption algorithm was so good that Zimmermann nearly went to jail after one of his associates posted the algorithms source code on the Web and it caught the attention of the U.S. Customs Service. The federal government wasnt happy that such a powerful secrecy tool had become available to anyone who wanted it and had the technical skills to use the complex program. It took a three-year legal battle before Zimmermann was eventually cleared of violating the International Traffic in Arms Regulations for exporting munitions.
Two years ago, after an unsuccessful attempt to make money on PGP on his own, Zimmermann sold PGP to Network Associates Inc. (NAI) in Santa Clara, Calif. NAI tried to integrate and market PGP as part of an all-in-one firewall, virtual private network and peer-to-peer encryption appliance but was unable to sell the product, says Ryan McGee, group product manager at McAfee Security, a division of NAI. Nor could the company find another vendor to buy PGP. So in February, it pulled support for the product
