Private Communications Technology

Overview#

Private Communications Technology (PCT) was a protocol developed by Microsoft in the mid-1990s but has since been superseded by SSLv3 and Transport Layer Security.

Private Communications Technology 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 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.

Private Communications Technology it SHOULD NOT be used for new development.
