Upgrades Netscape Navigator and Communicator so that they support 128-bit cryptography. Fortify arranges for Netscape to generate and use 128-bit secret keys whenever possible. It achieves this by installing itself directly into the Navigator browser at a small number of specific places. Thus, no SSL proxy servers or relays are involved. No supplementary libraries or support programs are installed, no helper applications are needed and no special export certificates are required in either the server or the browser.
