[Doesn't this protection stem from the case where a manufacturer wanted to protect a program that handled the curing of rubber?] It may be that the RSA algorithm is protected in this way. The algorithm HAS been issued a patent (Patent 4,405,829 held by MIT and licensed by RSA Data Security Inc). Bob Devine
