The ITU's X.509 standard defines a standard format for digital certificates, the most-widely used PKI standard.
A standard defined by the International Telecommunication Union ( ITU) that governs the format of certificates used for authentication in public-key cryptography.
ITU-T recommendation specifiying aspects of digital certificates and PKI ITU-T Recommendation X.509 specifies the authentication service for X.500 directories, as well as the widely adopted X.509 certificate syntax. The initial version of X.509 was published in 1988, version 2 was published in 1993, and version 3 was proposed in 1994 and considered for approval in 1995. Version 3 addresses some of the security concerns and limited flexibility that were issues in versions 1 and 2. http://www.ietf.org/rfc/rfc2459.txt
