Key File

Key file is a special file stored on the local computer. It corresponds to the purchased license or activated demo period for Dr.Web for Linux. The file contains information on the provided license or demo period and regulates usage rights in accordance with it.

The key file has .key extension and is valid if satisfies the following criteria:

License or demo period is not expired

Demo period or license applies to all anti-virus components required by the product

Integrity of the key file is not violated

If any of the conditions are violated, the license key file becomes invalid.

During Dr.Web for Linux operation, the key file must reside in the default /etc/opt/ directory and have the drweb32.key name.

Components of Dr.Web for Linux regularly check whether the key file is available and valid. The key file is digitally signed to prevent its editing. So, the edited key file becomes invalid. It is not recommended to open your key file in text editors in order to avoid its accidental invalidation.

If no valid key file (license or demo) is found, or if the license is expired, operation of the anti-virus components is blocked until a valid key file is installed.

It is recommended to keep the license key file until it expires, and use it to reinstall Dr.Web for Linux or install it on a different computer. In this case, you must use the same product serial number and customer data that you provided during the registration.

Key File Installation

If you have a key file corresponding to the valid license for the product (for example, if you obtained the key file by email or if you want to use Dr.Web for Linux on another computer), you can activate Dr.Web for Linux by specifying the path to the key file.

You can specify the key file path

in the License Manager by clicking Other activation types on the first step of the registration procedure and specifying the key file path.

manually. For that purpose

1.Unpack the key file if archived

2.Copy the file to the /etc/opt/ directory and rename it to drweb32.key

You can also use the following command:

$ drweb-ctl cfset Root.KeyPath </path/to/key/file>

In this case, the key file will not be copied to the /etc/opt/ directory and will remain in its original location. If so, the user becomes responsible for ensuring that the file is protected from corruption or deletion. This installation method is not recommended as the key file can be accidentally deleted from the system (for example, if the directory, where the key file resides, is periodically cleaned up).
