Hi all,

Step 1. Write your Usenet article, including all headers,
in nano, notepad etc.

Step 2. Sign it with gpgsv[1]

Step 3. Encrypt the article for mail2news@oc2mx.net with:

-----BEGIN PGP PUBLIC KEY BLOCK-----

mDMEaY9LuxYJKwYBBAHaRw8BAQdAHt7yNTKHC/KtVVAm36F9Qo/wxTYNrt8idrUL SOSdb3a0H21haWwybmV3cyA8bWFpbDJuZXdzQG9jMm14Lm5ldD6IlgQTFgoAPhYh BKcjiFJ+k1v+7jK8YdzFFe28xbvMBQJpj0u7AhsDBQkFo5qABQsJCAcCBhUKCQgL AgQWAgMBAh4BAheAAAoJENzFFe28xbvMLWsA/1PNnDFBkpxC1Ajh+FSEa6GPYewW CGs0S61o7bMNFwD8AP9b/2rZJyAnkO/6EfOv8p1dKVgrixQx+3mmNFzEMY+qA7g4 BGmPS7sSCisGAQQBl1UBBQEBB0B96skxGcz05cxY41nfMCT16tLJ3q2WmBoxWTmQ S7MCdwMBCAeIfgQYFgoAJhYhBKcjiFJ+k1v+7jK8YdzFFe28xbvMBQJpj0u7AhsM BQkFo5qAAAoJENzFFe28xbvM3lMBAKkKcGYNhDW7t+nkokN/idQLuc0xcVstwcXA N7QFEw/+AQDJnK2TYYBmtCFauvMqAjsqV7vJBr+ZbES43tm8Sg+LCw==

-----END PGP PUBLIC KEY BLOCK-----

Step 4. In your web mailer use in the To: field mail2news@oc2mx.net,
leave the Subject: empty and copy the encrypted message in
the message Body field of your web mailer.

That's all! Now you have an OpenPGP signed Usenet article in your
favorite Newsgroup posted. The advantage of this is, if you use a
freeform OpenPGP UID for your key and a fantasy email address
only your friends know it is you and your web mail provider does
not see the content of your Usenet message, nor does he know to
which Usenet group the article weent. And in case of remailer usage
nobody knows what the exit remailer was, as my m2n does not log
or store messages.

Hope you like!

And this PGP signed article was sent via Tor and the Mixmaster Network.

Chain: middleman,dizum,iria

Because this message is signed too, we can later see from the signature
date and the posting date the latency.

Without PGP signing users have the ability to use for every exit remailer
a custom From: header, which is IMHO a big bonus too.

Well, not so much latency for three hops, which is o.k. for me.

I am thinking of that I may implement a latency pool like Mixmaster
has, but encrypted, in the future.

I don't see any explanation on how to use gpgsv-windows-amd64.exe.
It doesn't have a CLI. Might want to put -h and --help in execution
string.
