And also I ported it to mac OS X to fuzz OpenCL and CUDA. The fuzz.pl and fuzz_mac.pl are attached. You can also get it in my jumbo fork. https://github.com/loverszhaokai/JohnTheRipper/tree/fuzzing/fuzz/script I add ChangeCase and InsertDictionary method. ChangeCase will change each char to upper case and lower case, it will also change all chars to upper case and lower case. InsertDictionary will insert strings before each char if the length of hash is less than 50, otherwise it will inert strings before and after those chars: ".,:#$*". The inserted strings are from dictionary, and I created an dictionary which is attached. The strings in the dictionary is from the found bugs which is likely to trigger bugs. The InsertDictionary found one bug by insert long strings: https://github.com/magnumripper/JohnTheRipper/issues/1434 Thanks, Kai Content of type "text/html" skipped View attachment "fuzz_dic.txt" of type "text/plain" (98999 bytes) View attachment "fuzz_mac.pl" of type "text/x-perl-script" (8837 bytes) View attachment "fuzz.pl" of type "text/x-perl-script" (8455 bytes)
