Julien, Unfortunately the documents are from a business partner of a client; had I created them myself I most certainly would not have protected them :) I've looked in my keychain and I have no related credentials. When viewing the file in both Preview and Skim, a password is not prompted for, the document is displayed in its entirety, and the document's properties show "Encrypted" as "Yes".
If I attempt to just go ahead and strip the text out using PDFTextStripper, ie catch-and-ignore any exceptions arising from decryption, I still get Caused by: org.apache.pdfbox.exceptions.WrappedIOException: Error decrypting document, details: at org.apache.pdfbox.util.PDFTextStripper.writeText(PDFTextStripper.java:250) at org.apache.pdfbox.util.PDFTextStripper.getText(PDFTextStripper.java:184) ... 24 more Caused by: org.apache.pdfbox.exceptions.CryptographyException: Error: The supplied password does not match either the owner or user password in the document. at org.apache.pdfbox.pdmodel.encryption.StandardSecurityHandler.decryptDocument(StandardSecurityHandler.java:231) at org.apache.pdfbox.pdmodel.PDDocument.openProtection(PDDocument.java:1111) at org.apache.pdfbox.pdmodel.PDDocument.decrypt(PDDocument.java:591) at org.apache.pdfbox.util.PDFTextStripper.writeText(PDFTextStripper.java:246) ... 25 more The encryption dictionary is as follows (I omitted the user and owner strings): 132 0 obj<</R 4/Length 128/Filter/Standard/O(...)/P -1324/U(...)/V 4/CF<</StdCF<</Length 16/CFM/V2/AuthEvent/DocOpen>>>>/StmF/StdCF/StrF/StdCF/EncryptMetadata false>> endobj Thanks again, Gary On Fri, Aug 27, 2010 at 2:45 PM, Julien Plée <[email protected]> wrote: > Hello Gary, > > You may try to open it in an other free reader not based on the MacOS > library. > Either I would think that: > 1) you stored the password in keychain > Or 2) you didn't protect the documents > > Regards, > > Julien > > > > > Hello all, >> >> I have a collection of PDFs I'm extracting text from programmatically, and >> some of them are encrypted.
