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?
That means that you did something incorrectly. If you sign the message correctly, it should be verifed.
What software did you use for signing message?
So for this particular example I had used samurai wallet which is actually now seized and not usable because the creators were arrested by the feds for money laundering. However, when I was attempting to make my first one I just used a new address of mine that I hadn't used for anything yet. I have a screenshot of it but I can't post pictures
