Reading Files/Directories and Hashing with Python

Description: Module to calculate the MD5 values of JPEG files within directories and subdirectories

Usage: python.exe MG-Reading-Files-hashing-bytes-of-jpg.py

Notes: The following files are the main files:

  1. MG-Reading-Files-hashing-bytes-of-jpg.py --- The python (*.py) file you need to run ---

  2. JPG-Results.txt --- The Output text generated after checking files, it contains results ---

  3. Sample-Output.txt --- Text File with Sample Output ---

  4. .gitignore

  5. readme.md

  6. readme.txt

  7. requirements.txt

  • The rest of the files inside directories are for testing purposes, they will be checked in addition to the above files.

  • Criteria of checking files:

    If file is jpg or not

      If file is jpg then read the first 4 bytes



  	If the first 4 bytes match the globally defined header jpgHead = b'\xff\xd8\xff\xe0'


  	Return MD5 Hashing value of the jpg file and store output it in JPG-Results.txt

  • Try and Except statements were used to check existence of a file or directory, and to try to open them.

  • The program is supposed to handle all errors associated with checking and opening these files and returning proper messages accordingly.
