Hi guys this is really important i searched an example code about "Username and Password Validation between Server and Client" through internet a LOT and i couldn't find anything... so please guys if any of you guys have anything about this topic please show me here thanks a lot guys!!!
Generally the client sends a password (string) to the server. The server performs some algorithm on that string (like MD5 hash) and compares the result against a stored value. This way the server doesn't have the password itself stored and so passwords can't be leaked.
