["Martijn Brinkers (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PDFBOX-858?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12934351#action_12934351 ] 

Martijn Brinkers commented on PDFBOX-858:
-----------------------------------------

You should decrypt the document before parsing:

            if (document.isEncrypted())
            {
                try {
                    /*
                     * Try to decrypt with standard password
                     */
                    document.decrypt(null);
                }
                catch (CryptographyException e) {
                    // handle
                }
                catch (InvalidPasswordException e) {
                    // handle
                }
            }

The meta info seems to be encrypted with the default password. The meta info can be read by me when the PDF is decrypted.

> On certain PDF files (examples attached), the metadata extraction seems to be broken. Preview (on Mac OS X) and Acrobat Reader is able to read the metadata, but PDFbox gives complete jibberish:

> I've tried both the version included in Tika 0.7 (1.0.0 I believe) and r1021264 from SVN.
