Why would you claim only one person possessed the secret key? As you doubtlessly know, some of the TruthMonger secret keys have been posted to Cypherpunks anonymously. This is not authentication. Thank you.
Prove it. Post the archived message where these secret keys were posted. Let's see the one which signed: http://www.inet-one.com/cypherpunks/dir.97.12.04-97.12.10/msg00356.html Note to the clueless guy@panix.com, who asks:
Entirely unexplained is how one goes from passphrase "sog" (Shit on government?) to decrypting the PGP message.
I'm impressed. You're actually stupider than Jeff Gordon, the IRS flunky. He was able to figure it out, so why don't you try. Ask your kindergarten teacher to give you a gold star once you fumble your way to the answer.
