Fix/Improve existing C++ exe application

Fix/Improve existing C++ exe application Important! Before i pick a provider i want to know what solution he can provide for each point marked with an * and mutually agree on the solution proposed. This to avoid misunderstandings. I need someone to fix and improve an application that has been made for me. I will provide source files when i have picked the provider. The modified source files have to be returned upon project completion along with a changelog of modifications done on this app. The current app. is attached to this project. Description of the application: ------------------------------- The application is a member registering client. Users are registering or login in with my site via this exe application instead of registering on the site itself. The application is used for a php website running on MySQL db and linux server. The app takes care of registering new users to our db by collecting the user's nickname, password, e-mail adress etc.. + the application gathers information on the user's hardware config in order to create a guid. All this info is encrypted and then sent to our db and is used to create the user account. Main functions of the app are: ------------------------------ [login to view URL] new users to a website: The user completes a new user form by entering his desired nickname, password, e-mail. [login to view URL]: Upon registering, the app gathers info from the user's local machine's hardware in order to create a guid. [login to view URL]: The app. encrypts all the collected data before it sends it to the website. Data is send using html form and goes through an internet browser application (IE) [login to view URL]: User can login to the site through this app., send data is encrypted here as well. Job description for this project: --------------------------------- 1. The app. must work regardless which popular Internet browser (IE - Firefox - Netscape - Opera ) is used on the user's pc ( seems that the registering process fails when user does not have IE-Internet Explorer installed ) If the problem does not come from the internet browser then i need you to find and fix the problem. 2. Some e-mail formats doesn't seem to work or are not accepted with the app. This has to be fixed. *3. Current guid function does not support hardware configs using SCSI or RAID controllers, this has to be fixed or propose an alternative and quick solution to be able to give users with such hardware configs the possibility to register. *4. Improving guid function. New solution will have to work regardless which hardware config a user may have or Windows OS is running (major OS versions). 5. Create a new function: I want to have a new function which is to update a user's current account. Basically, if user is not recognised anymore by the website because he made a change to his hardware config, he must have an option to update his account details by sending an account update request to the site. *6. With an eye for next improvement project here on GAF after this one has been completed I would like: - to be advised or informed which possible security measures can be used to reduce the risk for this application to be altered or cracked by "hackers" or limit their possiblities to fool the app itself. - Give me a quote for converting the 'guid function' used in the app. into a .dll. - Discuss and provide a quote for a new function that i want to add in the application. Requirements for this project during developments: -------------------------------------------------- - I need daily updates and test files. - Last escrow payment will be done when all is tested and working correctly and all bugs resolved. You keep source files for guarantee. I am a honest client and often pay a bonus when i'm satisfied of the works done. Urgent job, need it done fast and good.
