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 “Define 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

• 64 bit Open SSL binaries

• 32 bit Open SSL binaries

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.
