Can I send you or anyone a signed message in message form too see if it's good to post publicly? Someone trustworthy
As long as you don't share your private key, you are safe. You can share your signed message.
To verify your signed message, the message, the signature and the address are required.
Ok thank you for that, now suppose I had created a signed message myself and then when I go to put it in and verify, it shows invalid. Why would that be?
