Complete our C program wiht online licence check

I am very proficient in c, c++. I have 15 years c++ developing experience now, and I have worked for 5 years. My work is online game developing, and mainly focus on server side, the language is c++ under linux. I used c++ to make many great projects, for example, I made the tools which can convert java files to c++ scripts which has the same effect, of course garbage collection included. I also made our own mobile game using c++, I even can show you the demo of client. Trust me, please let expert help you.

Hi, I have previous experience with building online license checking system, that uses approach similar to popular license managers like FlexLM - set of features with expiration dates and digital signatures for the each feature, with and without hardware ID lock. I have recently implemented such system for securing RServe - the remote R script execution engine. But license check procedures are implemented there in R language and for Windows, which you are unlikely to use (and I don't recommend unless you really need). So I can implement for you the similar thing completely in C/C++, and for Linux, What I have already did, works as follows: for the you licensed app you specify additioanl config parameters: license server host and port, and license UUID. Application connects to server, passes it license UUID and receives online license text as response and checks whether required features are available, whether digital signatures are correct in the license and they are not expired. Server is based on the normal web server, you will be able to use any web hosting with PHP & MySQL or PostgreSQL. BUT - I'm not a web developer and will not write you a frontend to manage license contents visually via web interface. The project timeline can be discussed, but generally not shorter than towo weeks, project cost however is significantly higher than you offer right now in the project description. Please contact me if you are interested.

Hi! My name is Konstantin. I'm skilled Linux software developer. I have a lot of experience in low-level Linux development including building custom kernel, low- and high-level networking, etc. Previously I successfully implemented several software protection and licensing subsystems for Windows and Linux platforms. I also can suggest additional system characteristics can be used for security checking depending on your software type and internal structure. Software code patching protection and anti-cracking obfuscation can be implemented in future. Can you please provide more details about your software and your expectations for licensing, how it should work, how secure it should be and what king or infrastructure you planning to use at remove server side to support licensing?

Hello. The idea: 1. Is to create a hash for a particular computer dynamically. That is, each time you start the program or applying for a license check. 2. Check Function, or the entry point it can be selected in the program based on the response of the license server. 3. Periodically check hash generated by these parameters and check it out. Best regards.
