I've tried this today last few days.
but how in the heck do I get a message to look like a form of this?
The template shared by thymos
-----BEGIN BITCOIN SIGNED MESSAGE-----
My account <account> has been hacked/lost. Please reset the email to <email>. The current date is <date>.
-----BEGIN SIGNATURE-----
<insert address here>
<insert signature here>
-----END BITCOIN SIGNED MESSAGE-----
I sign a message in bitcoin core client and it comes out like this.
Nothing like the above quote.
