This template is no longer in use as it results in poor readability. This function verifies whether a password matches a password hash.

Syntax

bool passwordVerify ( string password, string hash[, function callback] )

Required Arguments

  • password: The password to check.
  • hash: A supported hash (see passwordHash)

Optional Arguments

  • callback: providing a callback will run this function asynchronously, the arguments to the callback are the same as the returned values below.

Returns

Returns true if the password matches the hash. Returns false if the password does not match, or if an unknown hash was passed. If a callback was provided, the aforementioned values are arguments to the callback, and this function will always return true.

Example

[[|link=|]] Warning: If you will be using "Example 1" then you will have to save account data "hash_password" after server restart, otherwise this script will no longer work.

This example makes use of passwordHash and passwordVerify in account creation and account login to boost up security.

Example 1
-- lets add command handler that will handle the account creation
addCommandHandler("accountCreate",function(source,cmd,username,password)
	if (username and password) then
		local hashedPassword = passwordHash(password,"bcrypt") -- create new hash for password
		if (hashedPassword) then -- check if hash has been generated
			local account = addAccount(username,hashedPassword)
			if (account) then -- now lets add account with new hash what we got when we made it for password.
				setAccountData(account,"hash_password",hashedPassword) -- store accounts password hash in order to verify it when it's needed.
				outputChatBox("Account successfuly created! Now please login. Syntax </accountLogin [username] [password]>",source,20,160,20)
			else
				outputChatBox("Account already exists! Please try again with different username.",source,20,160,20)
			end
		else
			outputChatBox("Securing your password failed! Please try again or contact an administrator.",source,160,20,20)
		end
	else
		outputChatBox("Wrong parameters! Correct Syntax </accountCreate [username] [password]>",source,160,20,20)
	end
end);

-- lets add command handler that will handle the account login
addCommandHandler("accountLogin",function(source,cmd,username,password)
	if (username and password) then
		local account = getAccount(username) -- get entered account
		if (account) then -- check if entered account exists
			local hashedPassword = getAccountData(account,"hash_password") -- lets get hashed password
			if (passwordVerify(password,hashedPassword)) then -- check if hash and entered password matches
				if logIn(source,account,hashedPassword) then -- now lets login player into account
					outputChatBox("Login successfull. Welcome, "..getAccountName(account).."!",source,20,160,20)
				end
			else
				outputChatBox("Password is incorrect!",source,160,20,20)
			end
		else
			outputChatBox("Account doesn't exist! Please try again with different account.",source,160,20,20)
		end
	else
		outputChatBox("Wrong parameters! Correct Syntax </accountCreate [username] [password]>",source,160,20,20)
