Quote from: nawlinsx on August 02, 2012, 06:48 pmThanks everyone for the encouragement.I'll be back later with more complete answers to your questions.As for the vendor I mentioned who has been forwarding orders in cleartext via GMail, I showed him this thread and he understands now why that is unacceptable. I pointed him to some resources and offered assistance with PGP running under Windows..Excellent.Quote from: nawlinsx on August 02, 2012, 06:48 pmIt is GPG on MacOS that has ME stumped this time around... The suite of applications it includes appears to support encrypting/decrypting of in/outbound emails... I don't understand what to do with the messages that come through SR? Where do I put them?Again, thanks.If you're using Snow Leopard or Lion then you should have GPG Services installed with GPGTools which enables you to use GPG functions with standard Mac applications (e.g. Finder, Safari, TextEdit, etc.). Some details are available on the GPG Services page:https://www.gpgtools.org/gpgservices/index.htmlIf you are on Leopard then unfortunately you don't have this option. If you are on Leopard then you might want to add another GUI frontend to obtain other functions. The main list of frontends for all operating systems is here:http://www.gnupg.org/related_software/frontends.en.htmlThere may be other options depending on what software you have and which version of OS X you're using.
