Description:
This will be an interesting project for someone!
We need an application that will be used internally to "protect" an EXE. The app doesn't need to be user-friendly, it will only be used by me.
I will provide this program with three pieces of information: a special URL (to check a customer before unlocking), the program name, and the EXE to be protected. All this information is compressed and compiled down into another EXE, one with no dependencies.
When run, this EXE prompts for the user e-mail address. It then sends this, along with the program name, to the URL I provided earlier, ie:
http://www.myserver.com/validate/page.asp?email=testATtest.com&app=MyProgram
It reads the response from our server: if it returns "true", then this app extracts and runs the EXE (preferably it's extracted to memory and run from there, else extracted to some temporary folder with a curious name and deleted afterward!). If anything the server does NOT return true, the user cannot go any further.
It sounds complicated but is relatively simple. Please ONLY bid if you can do this project. Most probably a C++ job, tho any language considered.
Please, no blanket bids -- please provide an understanding of this requirement in your bid.
Deliverables:
1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request.
3) Complete ownership and distribution copyrights to all work purchased.
Platform:
All Windows versions

Here's my synopsis of how I'd build this tool.
I'd build a command-line tool that would accept the three parameters outlined above. ( I'd recommend a fourth ... an encryption password ).
This tool would encode the specified EXE within a wrapper EXE using the encryption password.
The wrapper EXE would prompt the user for their credentials and would forward them to the web server via http only ( no https ).
Rather than returning true/false in the credential match-up, I'd recommend that the web page return a decryption key. ( This way, the user could not spoof the http lookup with a dummy boolean value. )
The decoded EXE would be written to a temp area.
Prior to spawning the EXE, the wrapper would write a short environment string that your EXE would look for and verify. ( This would prevent anyone from running the EXE from Explorer or a command-prompt; it must be invoked from the wrapper. )
