I was trying to get access token with pure autohotkey code.
But, there is no sutiable library for rsa encryption. So i have to make the new one. but that is very hard way. so i made dll using 3rd partition.

And below is the c# code in the dll.
No harmful.

            using (var stream = new FileStream(jsonKeyFilePath, FileMode.Open, FileAccess.Read))
            {
                return await GoogleCredential
