You can use v6 to encrypt files. It's a little cumbersome, and I am not sure why it's not .pdf and .enc, but instead some HL7 thing. I mean I know what HL7 is, but it doesn't seem like it belongs in the process. I think other encryption techniques are easier as Jon mentioned and having the ability to right click and encrypt is much faster. But, I suppose it makes the program that much more "meaningful."
Sorry that it didn't turn out as well as I would have hoped. Needed v6 and I had to install that on my VM, so I guess it didn't look as good.
