!!! Overview
[{$pagename}] ([PCT]) was a [protocol] developed by [Microsoft] in the mid-[1990s] but has since been superseded by [SSLv3] and [Transport Layer Security]. 


[{$pagename}] was designed to address security [Vulnerability] in version 2.0 of Netscape's [Secure Socket Layer] ([SSLv2]) [protocol] and to force [Netscape] to hand control of the then-proprietary [SSL] [protocol] to an open standards body.

PCT was designed to address security flaws in version 2.0 of [Netscape]'s [Secure Sockets Layer|SSL] [protocol] and supports most of the [Cipher Suites] supported by [SSLv2].
Some say this was done to force [Netscape] to hand control of the then-proprietary [SSL] protocol to an open [standards] body.

[Schannel SSP] supports PCT 1.0 for backward compatibility only.
