The United States and 32 other nations that belong to a group called the Wassenaar Arrangement, which coordinates export policies for technologies that have both civilian and military use, have signed an agreement restricting exports of encryption technology from their countries. The Clinton administration, which has already imposed such controls in this country, says the agreement will help American companies compete on a more equal footing with their counterparts abroad. Privacy organizations are critical of the agreement, and a counsel for the advocacy group Americans for Computer Privacy says there will still be enormous differences in how the countries put the agreement into practice.
