iTextSharp in version 4.1.6 (with previous licence conditions)

Question

I have an old project that is using iTextSharp library for PDF generation. iTextSharp DLL is added as reference to the project. iTextSharp was originally available under the LGPL licence. Some time ago the licence has changed to be AGPL (in release 5.0.0) that is copy left so you'd have to GPL all your code if you used it.

My problem is that I don't know when I downloaded the DLL file that is linked in my project. I don't know if the DLL is still under LGPL or it is already under AGPL. And that would mean that I have to GPL my project.

Is there any way to check what is the version of iTextSharp when you have only the DLL? Or what is the licence of it?

Or is there any place where I can download old version of iTextSharp that is still under LGPL so I'll be sure I'm not breaking the licence by not making my project GPL?

Answer 1

seems like iTextSharp maintainers removed iTextSharp 4.1.6 from SourceForge, anyway you can try to simply Google for "itextsharp-4.1.6.zip" to find alternative download sources
