Pretty Good Privacy

Pretty Good Privacy
Pretty Good Privacy (PGP) is a data encryption and decryption computer program that provides cryptographic privacy and authentication for data communication. PGP is often used for signing, encrypting, and decrypting texts, e-mails, files, directories, and whole disk partitions and to increase the security of e-mail communications. It was created by Phil Zimmermann in 1991 while working at PKWARE, Inc.[1] PGP and similar software follow the OpenPGP standard (RFC 4880) for encrypting and decrypting data. Design[edit] PGP encryption uses a serial combination of hashing, data compression, symmetric-key cryptography, and finally public-key cryptography; each step uses one of several supported algorithms. Compatibility[edit] As PGP evolves, versions that support newer features and algorithms are able to create encrypted messages that older PGP systems cannot decrypt, even with a valid private key. Confidentiality[edit] PGP can be used to send messages confidentially. Digital signatures[edit]

PGP Corporation PGP Corporation headquarters in Menlo Park PGP Corporation, co-founded by Jon Callas and Phil Dunkelberger, was based in Menlo Park, California.[1] PGP Corporation was funded by Rob Theis, General Partner, Doll Capital Management (DCM) and Terry Garnett, General Partner, Venrock Associates. The company owned the Pretty Good Privacy codebase, which was originally developed by Phil Zimmermann.[2] Originally written in 1991, Pretty Good Privacy (PGP) was one of the first freely and publicly available implementations of public-key cryptography. PGP Corporation's focus shifted towards the corporate market. On 2010 April 29, Symantec Corp. announced it had signed a definitive agreement to acquire PGP Corporation.[6] The merger was completed in June of that year. References[edit] External links[edit]

The company offered a toolbar that gave Internet users suggestions on where to go next, based on the traffic patterns of its user community. Alexa also offered context for each site visited: to whom it was registered, how many pages it had, how many other sites pointed to it, and how frequently it was updated.[6] Alexa's operation includes archiving of webpages as they are crawled. In 1999, Alexa was acquired by Amazon.com for about US$250 million in Amazon stock[8] as the company moved away from its original vision of providing an "intelligent" search engine.
