Why do you not use naclbox to communicate all the time? Couldn't it even be used for the cypherpunks mailing list, if the mailing list had a shared receiving private key, to verify that each person is saying what they intend?
Well, I often receive message in PGP format, because I still have a key pair for GnuPG. Otherwise I already use NaClbox with friends in Germany, the United States and Canada. :-)
Regarding the ML, I think the list-owner would not be amused and probably many subscribers would not like the idea either. For that people could use the Usenet group alt.anonymous.messages with a shared hashed subject (hsub) in order to fetch messages, from a.a.m..
I want to visit your link except what you said makes no sense to me. I think this subscriber crowd would leap on the idea of a nacl-based mailing list. Everybody knows that email is a crummy, weak norm. I'm going to wordwrap this whole message, pipe it to sha512sum, and encrypt the hash to your key. I'll paste it in to a terminal and end it by hitting ctrl-D on a blank line, then add a new blank line and the cyphertext at the bottom. Would you be interested in verifying the checksum? Here's the encrypted message you sent me, decrypted and rewrapped. I don't remember how many characters e-mail wraps to, this is my vim default. Would you be willing to reply encrypted, so I can have more confidence the reply has not been altered in transit? Would you be able to include my message in your reply, so I can know that you are replying to the same words that I sent? A man in the middle could have also made a naclbox identity, and if so we would want them to copy our words accurately. Sure, no problem. But as I posted this key I currently use is a *test* key on my online computer. Best regards Stefan
