#File Fuzzer

By Peter O. -- Public Domain -- [http://peteroupc.github.io/Fuzzer](http://peteroupc.github.io/Fuzzer)

----

This is a program that generates slightly altered versions

of data files, for testing algorithms that parse file formats.

It's a command line utility.

Usage:

Fuzzer.exe [fuzzer-xml]

fuzzer-xml is an XML file specifying configuration data. If not given, the fuzzer will

read the file fuzzer.xml. It has the following XML format:

    

     

     

     

     

     

     

     

     

     

    

* outputPath - Path of the directory to store the generated file.

* validFilesPath - Path of the directory containing files in a particular file

  format. The fuzzer will randomly manipulate these files to generate its

  test data.

* startBytes - A hexadecimal string specifying the bytes to write at the

  beginning of some of the generated files. Such files will contain random

  data following the header.

* fileExtension - File extension of the generated files.

* fuzzOffset - Byte offset of the point where the fuzzer will modify the

  bytes of the files located in _validFilesPath_.

* frequencyMean - Mean of the frequency of changes, in bytes.

* frequencyStdDev - Standard deviation of the frequency of changes, in bytes.

* iterations - Number of files to generate. Each file will be named XXXXX.YYY

  where XXXXX is a sequence of five or more digits and YYY is the file

  extension given in _fileExtension_.
