Re: Extraction of text from secured PDFs throws runtime exception

[Tilman Hausherr]

Hi,

always use the latest version of PDFBox, which is 1.8.8.
I don't know what happens in "PdfUtil.decryptPDFDoc". The correct call 
is openProtection().

I recently noticed the following runtime exception in my application 
when trying to extract text from secured PDFs:

java.lang.VerifyError: (class: org/bouncycastle/cms/CMSSignedDataParser, 
method: replaceSigners signature: 
(Ljava/io/InputStream;Lorg/bouncycastle/cms/SignerInformationStore;Ljava/io/OutputStream;)Ljava/io/OutputStream;)
 Incompatible argument to function

I am using PDFBox 1.8.6 and I use these APIs:

    document = PDDocument.load(is,true);

    if(document.isEncrypted()) {

         PdfUtil.decryptPDFDoc(document);

    }

    ...


I am assuming the error is occurring in the decryptPDFDoc() call?
My maven pom dependencies are:

    <dependency>
         <groupId>org.bouncycastle</groupId>
         <artifactId>bcprov-jdk15</artifactId>
         <version>1.44</version>
    </dependency>
    <dependency>
         <groupId>org.bouncycastle</groupId>
         <artifactId>bcmail-jdk15</artifactId>
         <version>1.44</version>
    </dependency>


Have I got this right?

Thanks for any pointers.
