Lines: 14 Berkeley Unix already has a public key encryption system used to send secret mail. It is called xsend and xget, and has been around for several years at least. (I don't know if it originated at Bell or not--all I know it is here on our vax.) Secret mail to each person is encrypted with their public key and kept in a spool directory, but then can of course only be read by that person themselves, who is the only holder of the private key. -- spoken: mark weiser UUCP: {seismo,allegra,brl-bmd}!umcp-cs!mark CSNet: mark@umcp-cs ARPA: mark.umcp-cs@CSNet-Relay
