It was founded in 2002, and acquired by Symantec in 2010. HistoryPGP Corporation was co-founded in June 2002 by Jon Callas and Phil Dunkelberger (who became CEO), based in Menlo Park, California.[1] It was funded by Rob Theis, general partner, Doll Capital Management and Terry Garnett, general partner, Venrock Associates.[2] The company owned the Pretty Good Privacy (PGP) software, which was originally developed by Phil Zimmermann (who had earlier started a company of a similar name).[3] Originally written in 1991, PGP was one of the first freely and publicly available implementations of public-key cryptography. It was originally used to allow individuals to communicate securely through bulletin board systems. PGP later became standardized and supported by many other applications, including email. PGP Corporation acquired the code and rights to the name from Network Associates (NAI) in August 2002.[4] The company released version 9 of the software in 2005. PGP Corporation's focus shifted towards the corporate market.[5] In 2004, the company announced plans to integrate with Symantec anti-virus technology.[6] In 2009, Callas left to be a security consultant.[7] In February 2010, the company acquired certificate authority TC TrustCenter and its parent company, ChosenSecurity, to form its PGP TrustCenter division.[8] On April 29, 2010, Symantec Corp. announced the acquisition of PGP Corporation for about $300 million cash.[9][10] The merger was completed in June of that year. The second developer hired, Hal Finney, went on to become the bitcoin network's first transaction recipient in 2009.[11] References1. ^1 {{cite web |title=PGP Corporation Corporate Backgrounder |publisher=PGP Corporation |url= http://download.pgp.com/pdfs/datasheets/PGP-Corporate-Backgrounder.pdf |date= June 30, 2008 |accessdate= November 8, 2016 }} 2. ^{{Cite web |title= Form D: Notice of Sale of Securities |publisher= US SEC |date= April 4, 2003 |url= https://www.sec.gov/Archives/edgar/vprr/0301/03019662.pdf |accessdate= November 8, 2016 }} 3. ^{{cite web |title= Why I Wrote PGP |date= 1999 |url= http://www.philzimmermann.com/EN/essays/WhyIWrotePGP.html |author= Philip Zimmermann |accessdate= November 8, 2016 }} 4. ^{{Cite web |title= Network Associates |work= Computer Hope web site |url= http://www.computerhope.com/comp/nai.htm |accessdate= November 8, 2016 }} 5. ^{{cite news |title=PGP reborn makes its pitch for the mainstream |author=John Leyden |work= The Register |date= October 22, 2002 |url= https://www.theregister.co.uk/2002/10/22/pgp_reborn_makes_its_pitch/ |accessdate= November 8, 2016 }} 6. ^{{cite news |title= PGP to integrate anti-virus defences |author=John Leyden |work= The Register |date= April 16, 2004 |url= https://www.theregister.co.uk/2004/04/16/pgp_adds_av/ |accessdate= November 8, 2016 }} 7. ^{{Cite web |title= Apple hires crypto-wizard Jon Callas to beef up security |date= May 24, 2016 |work= The Register |author= Iain Thomson |url= https://www.theregister.co.uk/2016/05/24/apple_hires_callas_to_beef_up_security/ |accessdate= November 8, 2016 }} 8. ^{{Cite web |title= PGP buys Chosen Security for trusted ID management |author= Dan Kaplan |work= SC Magazine |date= February 2, 2010 |url= https://www.scmagazine.com/pgp-buys-chosen-security-for-trusted-id-management/article/557354/ |accessdate= November 8, 2016 }} 9. ^{{cite web |url= http://www.symantec.com/about/news/release/article.jsp?prid=20100429_01 |title= Symantec to Offer Broadest Data Protection Capabilities with Acquisition of PGP Corporation and GuardianEdge |work= Press release |deadurl= yes |archivedate= May 2, 2010 |archiveurl= https://web.archive.org/web/20100502132932/http://www.symantec.com/about/news/release/article.jsp?prid=20100429_01 |accessdate= November 8, 2016 }} 10. ^{{cite news |title= Symantec buys PGP and GuardianEdge too: Crypto shopping spree |author=John Leyden |work= The Register |date= April 29, 2010 |url= https://www.theregister.co.uk/2010/04/29/symantec_buys_pgp/ |accessdate= November 8, 2016 }} 11. ^{{Cite news|url=https://www.nytimes.com/2014/08/31/business/hal-finney-cryptographer-and-bitcoin-pioneer-dies-at-58.html|title=Hal Finney, Cryptographer and Bitcoin Pioneer, Dies at 58|last=Popper|first=Nathaniel|date=2014-08-30|work=The New York Times|access-date=2017-10-22|language=en-US|issn=0362-4331}} External links
