may i ask, how to read this code

if others give code like that I'm confused how to read or how to find out that it was true
Why do you need to do that? It's a signature which tells us whether the message was signed by the address in question.
why do we need a sign message?
Signed message proves you have control over that address.
this puzzles me everytime i see someone asking for a sign message on an account or a wallet. how to determine that the message came from the account itself?
i understood how to sign a message, thanks to shorena for that. much appreciate.
since we are following and arrow going down, how to get the arrow going up and confirm the message is from the account or the wallet?
A signed message can be verified. If a person gives you signed message claiming it was signed with address
A and if it is successfully verified, the message *was* signed with address
A. But if the verification failed, message was *not* signed with address
A and hence, the person who gave you this doesn't have control over address
A.
well then i have another question, if the account was hacked and the hacker bruteforced the email address of the person, he can sign a message with the account anytime he wants since he can change the password of the account.
i understand its a plausible level of security since everybody urges the signature on almost every deal of accounts or loans. but i havent really understood how and how to know that the message is from the account and not just random
You are mistaken. Bitcointalk account and Bitcoin address are different. You are signing with a Bitcoin address not with Bitcointalk account.
