For example, sha256 has a fixed hash length of 64 characters. So I'm wondering will a password goes weaker as they get longer and longer? Since no matter how long your password goes, the sum will be 64 characters. So is there a known length of your password that exceeding the length will make your password weaker if the system is using sha256 to hash it?
