ce8f9b6608 MD5: switch to pluggable crypto 2019-11-09 08:18:02 -05:00
Jay Berkenbilt
5c3e856e9f Rename MD5 implementation (non-bisectable) 
Just rename MD5 -> MD5_native in place so that git annotate will show
the lines as having originated there.

34c0a88022 Local dev: use --std=c++11 explicitly 
Since g++ (as of this writing) uses c++14 by default, this prevents me
from accidentally using c++14 features.

653ce3550d Require C++-11 
Includes updates to m4/ax_cxx_compile_stdcxx.m4 to make it work with
msvc, which supports C++-11 with no flags but doesn't set __cplusplus
to a recent value.

5a842792b6 Parse Contents in signature dictionary without encryption 
Various PDF digital signing tools do not encrypt /Contents value in
signature dictionary. Adobe Acrobat Reader DC can handle a PDF with
the /Contents value not encrypted.

Write Contents in signature dictionary without encryption

Tests ensure that string /Contents are not handled specially when not
found in sig dicts.

06b818dcd3 Exclude signature dictionary from compressible objects 
It seems better not to compress signature dictionaries. Various PDF
digital signing tools, including Adobe Acrobat Reader DC, do not
compress signature dictionaries.

Table 8.93 "Entries in a signature dictionary" in PDF 1.5 reference
describes that /ByteRange in the signature dictionary shall be used to
describe a digest that does not include the signature value
(/Contents) itself.

The byte ranges cannot be determined if the dictionary is compressed.

5e0ba12687 Fix /Contents value representation in a signature dictionary 
Table 8.93 "Entries in a signature dictionary" in PDF 1.5 reference
describes that the value of Contents entry is a hexadecimal string
representation when ByteRange is specified.

This commit makes QPDF always uses hexadecimal strings representation
instead of literal strings for it.

0e51a9aca6 Don't encrypt trailer, fixes fuzz issue 15983 
Ordinarily the trailer doesn't contain any strings, so this is usually
a non-issue, but if the trailer contains strings, linearizing and
encrypting with object streams would include encrypted strings in the
trailer, which would blow out the padding because encrypted strings
are longer than their cleartext counterparts.
