data-hashing.py

A .py application to hash secure user entered sensitive data or passwords using the SHA3-256 Crypto Algorithm, to make one's available online data secure & resistive against possible data breaches online.

Fetching the repo

• Download the .zip file from here
• Unzip/Extract the directory.
• Open the extracted directory in VsCode or any other IDE of your choice.

How to execute

There are two ways to execute the application:

Executing .py file using Terminal

• Open the Terminal of your choosen IDE.
• Execute the main.py script, either by using the command:
  • py main.py (Python execution) or
  • nodemon main.py (Node/Nodemon execution)
  • (Make sure your system has Python/Node/Nodemon installed prior execution)

Executing .exe file

• After you have extracted the zip file, open it.
• Head towards the /dist/main/main.exe executable file location, link
• Execute the file with double clicking it, the application will be launched.

Using the application

• Enter your identity as asked (official/non-offcial)
• Enter the data/password you wanna hash
• The SHA3-256 Hash (HexCode) for the specified data will be generated

Commands

• Press -1: to terminate the application
• Press 0: to re-run main.py

Hashing used

• The hash algorithm used for hashing is SHA3-256
• It belongs to the SHA-3 Keccak hash family
• Based on the Sponge construction of cryptographic concept.
• A version of SHA3-256, the Keccak-256 is used in Ethereum Blockchain development.
• The hash has been fetched via Python's hashlib library.
