file-identifier

A simple CLI Tool scripted in Python to check for File types based on MIME types and then comparing them with the extensions.

Checks the File signature (Magic bytes) for known file MIME types
Known signatures are stored in the signatures.py file (can be populated manually to extend known type signatures)
signatures.py format {'extension' : ['list','of','signatures','in','hex','format']}
Example extry => {'gif' : ['47 49 46 38 37 61','47 49 46 38 39 61']}
After checking MIME type, the script also compares the identified type against the file extension (if present)

Based on all the above info, a compiled result is provided

Usage

file-id.py -f FILENAME_TO_SEARCH.EXTENSION
(or simply run the script without arguments and follow the on-screen instructions)
