Protect a Linux C++ Application

Requirements: QLM Enterprise v18+

Following is a step-by-step procedure to protect a Linux C++ app. Note that the steps below assume you have a QLM License Server already set up.

  1. Launch the QLM Management Console

  2. Create a product from the β€œDefine Product” tab or use the Demo 1.0 product if you are evaluating QLM.

  3. Go to the "Protect your application tab":

  • Page 1: Select the product to protect and the License Server then click Next

  • Page 2: Select "Other Languages"

  • Page 2: Select "Linux C++"

  • Page 3: Leave the default settings

  • Page 4: Select the folder where you want to generate the C++ source code and click Save

  • Page 5: Click Finish

  1. Add the generated files to your project (source and include folders)

  2. Install OpenSSL and copy the required OpenSSL to your bin folder

  1. The generated files also contain a test folder with a sample application that can be used as a reference for adding license activation and validation to your own code. Some parameters that may need to be updated in the sample are:

  • URL: URL to the QLM License Server

  • productID: Your product's Product ID as per the Define Products/Product Information tab

  • majorVersion: Your product's Major Version as per the Define Products/Product Information tab

  • minorVersion: Your product's Minor Version as per the Define Products/Product Information tab

  • publicKey: Your product's RSA Public Key as per the Define Products / Encryption Keys tab

To generate a license key for testing purposes:

  • Go to the Manage Keys tab.

  • Click "Create Activation Key"

  • Select the Product (Demo 1.0 for trials) and click OK.

  • Use the generated Activation Key to activate the license from within your application.
