X.509 Description
The Internet Engineering Task Force RFC 2459, entitled "Internet X.509 Public Key Infrastructure Certificate and CRL Profile", describes the protocols for the X.509 v3 certificate and X.509 v2 Certificate revocation list as a part of the Internet PKI. According to the RFC, "The goal of this specification is to develop a profile to facilitate the use of X.509 certificates within Internet applications for those communities wishing to make use of X.509 technology. Such applications may include WWW, electronic mail, user authentication, and IPsec." The structure of X.509 and the resulting PKI allow the owner of a public key to be certain that a private key is owned by the correct person, via the use of public key certificates digitally signed by a certificate authority.

Famous quotes containing the word description:
“Why does philosophy use concepts and why does faith use symbols if both try to express the same ultimate? The answer, of course, is that the relation to the ultimate is not the same in each case. The philosophical relation is in principle a detached description of the basic structure in which the ultimate manifests itself. The relation of faith is in principle an involved expression of concern about the meaning of the ultimate for the faithful.”
—Paul Tillich (1886–1965)
