WebIn a CTF, part of the game is to identify the file ourselves, using a heuristic approach. The traditional heuristic for identifying filetypes on UNIX is libmagic, which is a library for identifying so-called "magic numbers" or "magic bytes," the unique identifying marker bytes in filetype headers. WebHashing Functions. Hashing functions are one way functions which theoretically provide a unique output for every input. MD5, SHA-1, and other hashes which were considered secure are now found to have collisions or two different pieces of data which produce the same supposed unique output.
