I want to sign a message on Remix and I can't find the pair of private/public key.
For example - I going to Deploy & Run Transactions, then trying to "Sign a message using this account key" with the string "Hello! This is my message." and then I found the following result:
I need to verify the authenticity of the message with another account, then I need to know the sender public key...
Can anyone help me to find it?
