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
