Please forgive me if this is a topic covered before. I have just started to read this group. I have gotten involved with software distribution. Much of the software requires that a copy of a UNIX source licence be sent before I can send the software out. When I get the software, I then copy things to tape and mail the stuff out. When there is an update, I have to send tapes out again, or possibly mail the diff's. It would be very convenient if I could just use electronic mail to send things out (when the code is small, I'm not about to send multi-megabyte messages). To get around the problem with illicit reading of information, I thought that encrypting the code before mailing would be a good idea. When someone sent me a copy of their UNIX license, they could also send me the key to use in the encryption. When updates occured, I would merely encrypt the update and mail it off, secure in the knowledge that only the authorized party could read it. Is this approach a reasonable one? If it is, could someone send me either a pointer to an algorithm, an algorithm, or better yet, a program to do the encryption/decryption? Crypt(1) is not really feasible since many of the machines are not UNIX machines and the code for Crypt(1) belongs to AT&T. -- ---------------- Marty Sasaki net: sasaki@harvard.{arpa,uucp} Havard University Science Center phone: 617-495-1270 One Oxford Street Cambridge, MA 02138

The status of encryption algorithms as interpreted by the courts is extremely unclear. I would VERY strongly recommend AGAINST the distribution of licensed software materials via the networks, even if encrypted. You'd just be asking for trouble by trying it. --Lauren--
