CI Code Climate Gem Version

Description

ronin-fuzzer is a Ruby library and CLI for generating, mutating, and fuzzing data. The goal of ronin-fuzzer is to be both easy to use and highly customizable.

Features

  • Provides a Fuzzer class for incremental substitution fuzzing of data.
  • Provides a Mutator class for combinatorial substitution mutation of data.
  • Provides methods for enumerating over common "bad strings".
  • Provides core extension methods to Ruby's String class.

Synopsis

Fuzzes an input file and generates output bad files for testing:

$ ronin-fuzzer fuzz -i http_request.txt -o bad.txt -r unix_path:bad_strings

Examples

Replace every e, i, o, u with (, 100 As and a \0:

require 'ronin/fuzzing'

"the quick brown fox".fuzz(/[eiou]/ => ['(', ('A' * 100), "\0"]) do |str|
  p str
end
