I found the same question how-to-edit-the-created-pdf-metadata. I want to remove created date meta data from pdf document, which is generated by Telerik.Reporting.Processing.ReportProcessor().RenderReport.
As per our requirement, we create SHA256 hash from generated document, and compare it with previous one. Each time hash are mismatched.
As per initial analysis, I found that only Created Date meta data information is varying, which results hash mismatch.
