OK I have pinpointed a problem I was having earlier with printouts.
We have been having a problem where some of our clients were separately
experiencing an error where random PDF's would be
Thank you, I'll see how to integrate it.

Hello,
I met with a PDF file which does not embed font subsets and
consequently failed to extract text from it.
The fact that a font isn't embedded doesn't mean you can't extract text.
Text extraction doesn't need to know what a glyph looks like, it only
needs
iTextSharp is FIPS compliant. The MD5 need by the PDF is generated with the
bouncycastle library and won't be affected by the compliance flag turned on.

Onlu CJK Unicode is supported in text extraction. There's no major dificulty in
supporting other cmaps, it's just not done.

In my previous version of iTextSharp, I changed out all references of MD5 to
use SHA-256. Under that scenario, when I turned on the FIPS flag, my
application worked fine. The issue that prevented me moving forward at that
point was, PDFs that were being generated required a password to open,
Thank you for working on it.
The patch pack may contain some other fixes about the recently reported iText
issues, for instance, double-byte PDF Name decoding, etc.
The fix for 2GB+ PDF files mostly includes reading and writing the Xref table
and streams.
It may break existing codes since
You can't just blanket replace MD5-SHA-256, since there are parts of PDF where
you MUST use MD5 (and not doing so would create an invalid document).
Instead, you would need to disable the specific parts of iText that require MD5
and for others that can accept alternative hash algorithms, use
Where exactly does it break? What's the stack trace? I have it running with the

System.Security.Cryptography are ever called.

What does this mean?
PDF Names are always in UTF8, so they can NOT contain double-bytes (at least
not in native form)

Thanks guys - this has been on my 'to-do' list since July, and I haven't had
a chance to work on it yet - sorry.
Back then, I made the following proposal:
