X.509 is the most widely used standard for defining digital certificates. X.509 is an
International Telecommunications Union (ITU) recommendation, which means that the
standard has not yet been officially defined or approved. As a result, companies have
implemented the standard in different ways. For example, both Netscape and Microsoft use
X.509 certificates to implement SSL in their web servers and web browsers. However, an
X.509 certificate generated by Netscape may not be readable by Microsoft products, and
vice versa.
