Hi Karl,

You need to understand the basics of cryptography, but gpg man page
is not bad, once you get hang of it.

There is a pretty good introductions at:

I have a book Cryptography Decrypted by H X Mel and Doris Baker
which helped me a good deal.

    I do not have Seahorse installed I do not think. I am having 
problems I think because the only help is a man page. And I have no idea 
what the system is doing most of the time. I thought I was getting it to 
put the public key into a file but it failed. I can't figure out why.

    If you know of any good help for this version please pass it along.
