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.
