iText 7 add-ons and license keys
If you've purchased a commercial license for iText 7 and/or its add-ons, you have a license key. To properly use it, that means you're going to have to download the proper license key library.
The iText 7 add-ons for .NET are available on NuGet. The iText 7 license key library is a required dependency for these packages, so it will automatically be installed as well.
You can install the add-ons by typing the following commands in the NuGet Package Manager:
Because the Java add-ons and the license key library are closed-source, they are not available on the Maven Central Repository. You can get them from the iText Artifactory server. You can add this server as an additional repository in the
repositories section of your
settings.xml, as described in the Maven documentation. Maven will then automatically query this repository for the add-on jar files.
