Client/Server program updates

I created a client/server application which uses 120-bit AES keys to encrypt all outgoing data. Currently, this application can support multiple clients per server. Each client is capable of sending/receiving encrypted messages. The server has its own user database used for user authentification. This is what I want done: Server: Limit ammount of failed logins. Better login procedure. Client: Limit amount of trys to get password correct besides those set by server. Extras: File Transfer** Private messaging** Additional debugging ** Indicates priority ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. Complete copyrights to all work purchased. ## Deadline information I want the private messaging feature to be completed in a week. The file transfer should be done in a week and a half after the private messaging is completed.
