Online binary file viewer Use this viewer to browse the contents of a binary file as hexadecimal bytes and equivalent ASCII characters. I need to reverse it in C to become 4321 without structures or arrays to help me. How do I go about doing that? In essence, a file with contents 1100101 would become 0011010. I used command. It supports a number of great features Only supports PE/MachO/ELF file formats; No API/Plugins; Performance Limits; Must submit binaries to a group of hackers who started to make games and reverse engineering tools. - search in a drive by file extension - open file in binary mode and reverse its content and save the reversed file. A cursory search for the first few bytes lead to nothing (if they were known, they could indicate a magic number for this particular file type).
