Can that be done.
Yes, see below. It looks like you are using a web interface (Firefox) to send and reply to messages. I would suggest emerging Thunderbird (emerge -av thunderbird). There is an add on called Enigmail for this mail client that makes encrypting, signing and decrypting messages, much easier. You need gnupg, as well. > The message that I am repying to appears to be something, encypted > maybe, but I think anyone on this list that uses the tool can read it. > Am I correct? If the message is encrypted to them, then yes. If not, no. You need a secret key to decrypt a message that is encrypted, and if anyone seeing it is not on the list of recipients, they will not have that key. > I'm trying to get a full understanding of this thing. Ya'll know how I > am. lol With OpenPGP or PGP/MIME, you would have to share your public key with the other party - this would allow that party to encrypt messages to you. You would also have to have the public key of the other party to encrypt to them. For example, if you wanted to encrypt to me, you'd have to retrieve my public key from a keyserver or I'd have to send it to you. You would have to either sign a message (and have uploaded your public key to a keyserver), or send me your public key. You could then encrypt a message to me, and you could add yourself to the recipient list so you could read it. Then, when I received the message, I would be prompted for my secret key's passphrase - this would allow decryption of the message. Providing that I replied to you and chose the "encrypt" option, the entire message, including any quotes would be encrypted.
