With a little scripting, you could create a new ECC keypair (fast!)
for each
message, sign the keypair with your normal key, sign the message with the ECC
keypair. And when you want to backpedal on a signed message, publish the private
ECC key and say "look, anybody who downloaded my private key off the web could
have signed that message".
But then it would be imho advisable that you use a different timestamp
(time in the future), because
when verifying the published message the timestamp would be earlier than
the time the sec key would
have appeared on the net, right?
