Protect Mq5 code -- 2

I have 2 indicators in mq5 and I want to add a basic online license validation protection with date and key. My code in mq5 compiles perfectly. The protection can be based on the standard of mq5 forum, I don't need a high level of encryption, just a simple protection with online validation. If you are interested, please contact me. The gain is not big since it is not a big task, but I have other requests for ex5 for this code later. Looking forward to your reply.
