This was originally addressed to Phillip Zimmermann. Thank you for writting PGP. I have not run it on my Mac yet because my version of Stuffit is 2.0 which deems the PGP.sit file to advanced. I resist the incentives of compression program authors to produce frequent incompatible updates which cost money and delay for little apparent advantage. Compact pro is a shareware program that produces self expanding archives which presume no pre installed decompressor. It is available by ftp at sumex-aim.stanford.edu info-mac.util.compact-pro-133.hqx You may forward this to whomever does the Mac version or send me his email address. What I really am writting you about is to suggest that if you wrote "another" program compatible with PGP under a PFP license that I would pay at least $50 for it. I might pay more depending on my experience with the free version. I would accept delivery by email.
