 |
|
Hi!
I'm looking for a way to unlock password protected pdf files. To make it clear, I DO KNOW the password!
It's just getting on my nerves that I have to open the files in Acrobat Reader or xPDF instead of just typing "lpr *.pdf".
As I really have to print a whole bunch of PDFs, someone who can help would really save me some time...

| under winblows you can open them in Acrobat (NOT reader) and change the settings... i don't know about it in Linux |

That's not the point I'm up to...
I can get password free PDFs under Linux by printing them as Postscript from Acrobat Reader and then converting them to pdf again.
But I have to print more than 100 PDFs, most of them protected but with the same password.
I'm looking for a way to batch-remove the password, so that I don't have to print every single file from Acrobat Reader.
It's much simpler to batch-remove the password and then just "lpr *.pdf", but I don't know a tool that helps me to get rid of the password... |

That thing looks like it can fulfill my needs...except that I don't have it working yet.
| Code: |
ralph@fry multivalent $ java -classpath ./Multivalent.jar tool.pdf.Decrypt -help
java tool.pdf.Decrypt [-password <owner-password>] [-inplace] <PDF-file...>
|
So Multivalent seems to work on my system.
| Code: |
ralph@fry multivalent $ java -classpath ./Multivalent.jar tool.pdf.Decrypt -password Sharpe64 pdftest/IF_2004-01-20_Begleitunterlagen.pdf
pdftest/IF_2004-01-20_Begleitunterlagen.pdf: owner password required
owner password required
at tool.pdf.Decrypt.decrypt(Decrypt.java:71)
at tool.pdf.Decrypt.decrypt(Decrypt.java:52)
at tool.pdf.Decrypt.main(Decrypt.java:125)
ralph@fry multivalent $
|
But it doesn't decrypt the PDF File although I DO give the password.
The password is definately right, at least it works when I want to read the file in Acrobat Reader or xPDF.
Can you help me with that? |

The password I got is only the user password, not the owner password. I didn't know there were such differences.
Anyway I decided to go the "PDF encrypted -> PS -> PDF unencrypted" way.
So I try to convert an encrypted PDF to PS using acroread on the commandline. Still no luck...
| Code: |
ralph@fry multivalent $ acroread -toPostScript IF_2004-01-20_Begleitunterlagen.pdf
IF_2004-01-20_Begleitunterlagen.pdf: This document requires a password.
|
I can't find an option to pass the password to acroread on the commandline, now looking for different programs... |

Similiar problem here.
I'm working on an easy-to-use Desktop, based on KDE3.2 for my girlfriend, but don't want to use acroread.
Kghostview/KPDF doesn't support password protected files, so I'm trying to write a little script which encrypts PDFs before opening them, but PDF-Encrypt doesn't work as it should do. ;(
| Code: |
anna@emilie Multivalent-Tools $ java -classpath /home/anna/Programmdaten/Programme/Multivalent-Tools/Multivalent.jar tool.pdf.Decrypt /home/anna/Desktop/pdf/Allgemeine\ Hinweise.pdf
/home/anna/Desktop/pdf/Allgemeine Hinweise.pdf: java.io.IOException: decrypt first!
java.io.IOException: decrypt first!
at multivalent.std.adaptor.pdf.PDFReader.getCatalog(PDFReader.java:990)
at multivalent.std.adaptor.pdf.PDFWriter.<init>(PDFWriter.java:231)
at multivalent.std.adaptor.pdf.PDFWriter.<init>(PDFWriter.java:207)
at multivalent.std.adaptor.pdf.PDFWriter.<init>(PDFWriter.java:200)
at tool.pdf.Decrypt.decrypt(Decrypt.java:66)
at tool.pdf.Decrypt.decrypt(Decrypt.java:55)
at tool.pdf.Decrypt.main(Decrypt.java:136)
|
Does anybody know a solution?
Thx & Greetings

Since I'm not the only one with that problem, I put myself again at it...after hours of searching, finally a success:
| Code: |
gs -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=bla.pdf -sPDFPassword=Sharpe64 -f IF_2004-01-20_Begleitunterlagen.pdf
|
works for me!
Man I'm angry! It took my hours to find out that the working option for the user password is not -sUserPassword but -sPDFPassword !!!
Completely misleading, the gs manpage sucks more than anything else!
I'm too tired now to make a script and gotta learn for an exam...
If you don't want to make a script I'll do it on Monday or Tuesday next week, but you better PM me so that I don't forget...
So long and good night, hope I could help you a little... |
