A python script to generate a list of file hashes (made by chatgpt and tweaked by me cause im dumb and lazy)

HashCalc.md

[BETA] A Graphical (sorta) Hash Calculator

⚠️⚠️ THIS GIST IS NO LONGER MAINTAINED HERE AND HAS BEEN MOVED TO A GIT REPOSITORY WHICH CAN BE FOUND AT redtrillix/HashCalculator ON GITHUB ⚠️⚠️

Description

TBD

Contents

• hashcalculator_csv.py makes a comma seperated (csv) file that can be opened in a program like excel.
• hashcalculator_sql.py makes a database file for sqlite.
• hashcalculator_txt.py makes a plain text file, and unlike the above csv file, it isnt formatted in any way.
