similar to: [PATCH 0/1] Base64-encode non-printable data

Some of the data in names and string values were being unsafely printed, causing some types of XML processors to fail (e.g. Python's Expat). This patch checks for printability of each character and outputs base64 with an encoding attribute for unsafe data. --- xml/hivexml.c | 75 ++++++++++++++++++++++++++++++++++++++++++++++++-------- 1 files changed, 64 insertions(+), 11 deletions(-)

Reporting value data in attributes has two advantages: * The output of hivexml breaks Python expat processing if binary data makes it out. This was observed in Software hives. * Not having child text makes room for child elements.

Dealing with "1601-01-01T00:00:00Z" is unnecessarily awkward, especially since the value only represents a 0 found in the data.

This patch adds value_byte_runs and node_byte_runs. Each byte run represents the offset and length of a data structure within the hive, one per node, and one or two per value depending on the length of the value data. These byte run functions also add additional data sanity checks as a hive is being parsed, mainly checking that a node address actually points to a node, and similarly for values.

This patch series improves, but does not complete, OS X support for hivex. There are several outstanding issues before hivexml and hivexsh can run: * hivexsh uses open_memstream, which doesn't exist in OS X as near as I can see. Unfortunately, I'm inexperienced with autoconf, so I'm not sure how to employ AC_CHECK_FUNCS([open_memstream]) to conditionally add 'sh' to the

All, Greetings. I am new to this mailing list. We have been working with XML for digital forensics. One of the areas that we wish to create a schema for is the representation of registry entries. We are interested in hivexml as a tool for extracting the registry as an XML representation. In our discussion with possible users, we have generally come to the conclusion that it is useful to

I'm trying to build hivex 1.2.7 on Ubuntu 10.04, and get the following failure: Making all in xml make[2]: Entering directory `/opt/sandbox/src/hivex/hivex-1.2.7/xml' CC hivexml-hivexml.o CCLD hivexml hivexml-hivexml.o: In function `main': /opt/sandbox/src/hivex/hivex-1.2.7/xml/hivexml.c:86: undefined reference to `rpl_getopt'

Greetings. I am new to this list. I am writing to you about hivexml. Richard Jones told me that he was considering abandoning this program. Instead, I am willing to take over maintenance of it. I am involved in computer forensics. I are in the midst of developing an XML standard to describe the Windows Registry. There are several programs that export the windows registry at XML. I have

This changeset adds byte run reporters for node and value metadata in the hivexml program. This location reporting required several new ABI functions, which required new ABI return types. One benefit to the byte run functions is additional sanity checks, which have revealed new data or parsing errors when run on M57 patents images. An example error: Image: Charlie, 2009-12-11, available at

The infrastructure for modified-time reporting has been essentially unused. These changes report the registry time by treating the time fields as Windows filetime fields stored in little-Endian (which means they can be treated as a single 64-bit little-Endian integer). Some of the code changes necessary include: * Exposing the hive_h structure in the hivex header file (via generator.ml) *

hivexml on OS X was failing with a symbol-not-found error while dynamically linking. Adding iconv to libhivex fixes the issue and lets OS X process 'images/large' with hivexml. It took careful iconv autotool additions to get compilation working in Fedora as well, but these two lines build and run on OS X 10.6 and 10.8, and Fedora 17 and 18. Unfortunately, a separate issue is revealed

This patch adds byte run reporters for node and value metadata in the hivexml program. Each byte run represents the offset and length of a data structure within the hive, one per node, and one or two per value depending on the length of the value data. In order to add this metadata reporting, the following changes were put in place: * Split value_key function into value_key and value_key_len. *
