How to destribute an app with license included

Aspose.PDF Product Family
1

Hello, im currently testing aspose.pdf to see if it suite my needs, but one question I have (haven’t purchased a license yet) is when I do purchase a license and want to destribute my application, how do I include the license with it (c#, aspose.pdf) in a way that my clients cannot retrieve it?

Also, under the license terms, is it allowed for me to embed the aspose.pdf (c#) in a pyhron application? I don’t want to use the python binding as I find it rather slow than my embedding solution.

Hi @Batz1
You can set up a licence from Steam. That means you can choose how to read the license content: from an encrypted file, a resource, a network, etc.

Here is one example of how you can read a licence.

using System;
using System.IO;
using System.IO.Compression;
using System.Reflection;

namespace Aspose.Pdf.Examples
{
    class ExampleLicensing
    {
        public static void LicenseDemo()
        {
            License license = new License();
            license.SetLicense(GetSecureLicenseFromStream());
            Document doc = new Document("document.pdf");
            //Get the page count of document
            Console.WriteLine(doc.Pages.Count);
        }

        private static Stream GetSecureLicenseFromStream()
        {
            var assembly = Assembly.GetExecutingAssembly();
            var memoryStream = new MemoryStream();
            using (var zipToOpen = assembly.GetManifestResourceStream("Aspose.Pdf.Examples.License.Aspose.PDF.zip"))
            {
                using (ZipArchive archive = new ZipArchive(zipToOpen ?? throw new InvalidOperationException(), ZipArchiveMode.Read))
                {
                    var unpackedLicense  = archive.GetEntry("Aspose.PDF.lic");
                    unpackedLicense?.Open().CopyTo(memoryStream);
                }
            }

            memoryStream.Position = 0;
            return memoryStream;
        }
    }
}
