The recent relaxation of U.S. encryption export controls has made it more possible for U.S. and non-U.S. developers to work together on adding cryptographic functionality to open source applications. In particular, the Mozilla open source browser and mail/news client will be getting SSL capability as a result of code and developer time contributed by iPlanet E-Commerce Solutions and Netscape; other Mozilla-related crypto projects are being discussed. We'll explore the current state and future prospects for cryptographic functionality in Mozilla and also discuss compliance with the new U.S. export regulations and other crypto-related issues relevant to any open source project.
