decrypting a PDF to read the content
Hi All,
I got this error when i tried to decrypt a pdf document encrypted by
com.lowagie.text.pdf.PdfEncryptor class, with a null password:
"java.lang.NoClassDefFoundError: org/bouncycastle/cms/CMSException"
Does anyone know which version of Bouncy Castle is the right one to
use with PDFBox API? i dont know anything about Bouncy Castle.
I´m using the LucenePdfDocument Class, from the PDFBox API to decrypt
the document, with a null password.
Thanks in advance.
Alixandre

since this question seems to be entirely about extracting text with PDFBox
and not at all baout indexing the text once it's been extracted, perhaps
it would be better suited for the PDFBox forums...

I´m using PDFBox 0.7.3
The problem i think its that i´m encrypting a PDF with Itext, with a
"null" User/Owner password. Then i try to decrypt the doc with a class
from PDFBOx. Its exactly there that
occurs the exception. That is, a format incompability problem.
In addition, i didnt found the "org/bouncycastle/cms/CMSException" on
PDFBox lib, as you said. So...i tried to use the "bcprov-jdk15-135",
a bouncy castle provider. Nothing happened.
do you have any idea?
Thanks

PDFBox comes with a version of BouncyCastle that will work. It is
likely that other versions will also work as well.
Is there a specific version that you have tried and didn't work?
