使用PDFsharp打开AES 128位加密文件 [英] Using PDFsharp to open AES 128-bit encrypted files

问题描述

我一直在接收使用PDFsharp库处理的pdf文件.这些文件经过128位RC4加密.现在，我得到的是128位AES加密的文件.

I've been receiving pdf files that I have been processing with the PDFsharp libraries. These files where 128-bit RC4 encrypted. Now I getting files that are 128-bit AES encyption.

我遇到此异常"PDF文档受PDFsharp不支持的加密保护."

I'm getting this exception "The PDF document is protected with an encryption not supported by PDFsharp."

是否仅支持AES，还是需要更改打开文件的方法?

Is AES just not supported, or do I need to change the method in which I open the file?

     Using InDoc As PdfDocument = PdfReader.Open(InputFileName, Password, PdfDocumentOpenMode.Import)
            Using OutDoc As PdfDocument = New PdfDocument
                For Each page As PdfPage In InDoc.Pages
                    OutDoc.AddPage(page)
                Next
            End Using
  End Using

推荐答案

PDFsharp尚不支持Adobe 7+的AES.
