PDF decrypting with iText-5.2.1 revision 5117

[Valentin Ivanov]

I have encrypted PDF file.
with BC1.46 and iText-5.1.3 I decrypt the file successfully.
With BC1.47 and iText-5.2.1 HEAD revision i have exception :

com.itextpdf.text.exceptions.InvalidPdfException: Bad certificate and key.
at com.itextpdf.text.pdf.PdfReader.readPdf(PdfReader.java:515)
at com.itextpdf.text.pdf.PdfReader.<init>(PdfReader.java:203)

I have no touched the code. What could be the problem?
Thank you

[Paulo Soares-4]

The move to BC 1.47 still needs testing, it's very recent. Let's hope
it's not something broken in BC and the problem is in iText.

PDF decrypting works fine with BC1.46 and iText-5.2.1 (official release). It seems like the problem is not in iText.

[Kwan Hon Luen]

BC1.47 has renamed some classes and interfaces. That is the source of the
problems.

Maybe the OP still uses the wrong iText version. iText switched to BC 1.47 not before 5.2.2-SNAPSHOT. He mentions a 5.2.1 HEAD version.

Maybe he checked out svnroot/itext/tags/iText_5_2_1 at revision 5117 instead of svnroot/itext/trunk and, thus, actually uses the code designed for BC 1.46.

OTOH the exception says "Bad certificate and key". Maybe BC became a bit stricter concerning input formats (it at least used to be very lax concerning malformed data) and, therefore, now rejects the file.

Valentin, maybe you could provide an example PDF for this issue?

Regards,   Michael

[Valentin Ivanov]

yes, but then should not the exception show the missing BC "thing" in the stack trace? As Paulo says BC1.47 is recent version and need testing.
