- I'm interested in using secure mail or some sort, but my present
- options are insecure, inconvenient, or both.
-
- I have internet access through hosts that I do not control. As the
- PGP manual points out, this is very insecure. I can dial in, using a
- terminal emulator on a macintosh.
-
- For secure mail I seem to have two choices.
-
- The simple but inconvenient choice is to use kermit to xfer encrypted
- messages between my mac and my internet host. I don't like this
- because of the significant effort required to deal with encrypted
- mail: no longer could I simply "reply" to a message, or even read it.
- I'd have to
- 1. log on the unix box
- 2. write encrypted messages to a file
- 3. kermit the file to my mac
- 4. leave the terminal emulator, returning to the mac
- 5. decrypt the message.
- 6. compose a reply, outside of my standard unix mail environment
- 7. write reply to a file, encrypt it
- 8. kermit reply back to the unix box
- 9. go back to terminal emulator, send mail.
-
- This is simply too inconvenient to do on a large scale. Or even a
- small scale.
-
- An alternative which is more complex to implement, and requires
- changing the way I handle mail, but is much more convenient, is to
- read all mail on my mac. Ideally en/decrypting messages would be
- built into the mail reader, but at worst I could en/decrypt local
- files - avoiding the kermit steps above. But I don't know how to go
- about doing this. Are there products on the market that do this? Do
- I need to make my mac a full-fledged internet host?
-
- How have others dealt with this problem? Are there convenient and
- secure solutions?
-
- Finally, I have seen references to RIPEM, but don't know anything
- about it. Would someone fill me in or give me a pointer? I'm
- guessing it's a public key system, using the rsa algorithm, blessed by
- pkp. Is there a macintosh version?
-
- Thanks.
