Project description:
"I need to set up a simple, secure licensing workflow in my existing PHP server for a Windows C# desktop application.

Here’s how I picture the flow and what I need from you:

C# Software Licensing Task as briefly outlined below

1. Key Generation and Management
Generate an RSA public and private key pair on my web server using OpenSSL commands in PHP.

2. PHP Web Hosting (License Generation)
On your web server, you will have a PHP script that generates a license file containing the user's information, then digitally signs this data with my private key.

3. C# Desktop Software (License Verification)
In my C# application, the process involves receiving the license file, extracting the data and signature, and using the embedded public key to verify the signature.

Embed Public Key: Include the public key string within my C# application code.


Deliverables
1. PHP script with OpenSSL commands and clear install notes.
2. C# verification class plus a quick demo WinForms or console project showing it in action.
3. One test license file proving the round-trip works.

If that matches your expertise, let’s get it built." (client-provided description)
