CDMF.SYS
IBM's Commerical Data Masking Facility (CDMF) encryption driver
This driver is an early version of the IBM proposed new national standard encryption protocol (US) with a variable key of up to 128-bits. It supports the VPN (Virtual Private Network) built-in to the firewall of TCPIP 4.1 and later. This driver uses a larger data block than DES and is faster than competing protocol drivers. It is a enhanced version of DES. Many don't consider it as strong an algorithm as Blowfish or Ideal, widely available competitors to this protocol.
