Hi, Does Tika support detecting if a PDF has embedded files, and even better return an array of the file names?
I was forwarded a "signed" PDF from a vendor that appearantly makes their own signing solution. The PDF doesn't contain any standard PaDES properties that triggers the signature panel in Acrobat or hasSignature:true or any of the other signature properties in Tika. It consisted of embedding six html files with various technical info inside the PDF, like here, from the raw content: obj <</Names[(Appendix 1 Evidence Quality Framework.html) 99 0 R (Appendix 2 Service Description.html) 101 0 R (Appendix 3 Evidence Log.html) 105 0 R (Appendix 4 Evidence of Time.html) 107 0 R (Appendix 5 Evidence of Intent.html) 109 0 R (Appendix 6 Digital Signature Documentation.html) 103 0 R (Evidence Quality of xxxxx E-signed Documents.html) 97 0 R]>> endobj 112 0 obj >From a security perspective this would also be very useful when using Tika as >a secure file gateway for file analysis and detecting malicious files. Thanks, Willy T. Koch Norway
