Pretty Good Privacy

(tool, cryptography)(PGP) A high security RSA public-key encryption application for MS-DOS, Unix, VAX/VMS, andother computers. It was written by Philip R. Zimmermann of Phil's Pretty Good(tm) Software and lateraugmented by a cast of thousands, especially including HalFinney, Branko Lankester, and Peter Gutmann.

PGP was distributed as "guerrilla freeware". The authorsdon't mind if it is distributed widely, just don't ask PhilipZimmermann to send you a copy. PGP uses a public-key encryption algorithm claimed by US patent #4,405,829. Theexclusive rights to this patent are held by a Californiacompany called Public Key Partners, and you may beinfringing this patent if you use PGP in the USA. This isexplained in the PGP User's Guide, Volume II.

PGP allows people to exchange files or messages with privacyand authentication. Privacy and authentication are providedwithout managing the keys associated with conventionalcryptographic software. No secure channels are needed toexchange keys between users, which makes PGP much easier touse. This is because PGP is based on public-key cryptography.

PGP encrypts data using the International Data Encryption Algorithm with a random session key, and uses the RSAalgorithm to encrypt the session key.

In December 1994 Philip Zimmermann faced prosecution for"exporting" PGP out of the United States but in January 1996the US Goverment dropped the case. A US law prohibits theexport of encryption software out of the country.Zimmermann did not do this, but the US government hoped toestablish the proposition that posting an encryption programon a BBS or on the Internet constitutes exporting it - ineffect, stretching export control into domestic censorship.If the government had won it would have had a chilling effecton the free flow of information on the global network, as wellas on everyone's privacy from government snooping.
