HASH PROBLEM [HELP]

[Firespider]

Hello, I am writing the login part of the login panel and the problem is that I have to verify the enter

addEvent("login", true)
addEventHandler("login", root,
function (user, pass)
    local serial = getPlayerSerial(client)
    local dq = dbQuery(db, "SELECT * FROM accounts WHERE serial=?", serial)
    local result = dbPoll(dq, 250)

    	if (#result > 0) then
    		outputChatBox(pass)
    		local Pass = hash("sha512", pass)
    		outputChatBox(Pass)	
        if user == result[1]["username"] then
           
            if  Pass == result[1]["password"] then
                print("Sikeres bejelentkezés!")
            else
                print("Hibás jelszó!")
            end
        else
            print("Felhasználónév nem található!")
        end
    else
        print("Sikertelen bejelentkezés!")
    end            
end
)

ed password so that it matches the registered password, the two texts match, but the system detects that they do not match, is there anything I can do?
