General info

This project is a CLI (Command Line Interface) to hash individual files, compare between two files for integrity check or hash strings.

Libraries

Project is created with:

• hashlib library.
• argparse library.
• python 3.6 or higher.

Setup

To run this project, install all the required libraries first then run the python script:

$ pip install hashlib
$ pip install argparse
$ python hashy.py -hf (hash functions) [-f <file path> | -cf <file path> <file path> | -s <string>]

Usage

Run the following command to display help message

hashy.py -h

or

hashy.py --help

A help message will appear with all required arguments the program needs to run:

usage: hashy.py [-h] [-v] -hf MD5:SHA1:blake2b [MD5:SHA1:blake2b ...]
                (-cf <file path> <file path> | -f <file path> | -s "String")

Hashy is a CLI program to hash files, compare two files (integrity check),
strings.

optional arguments:
  -h, --help            show this help message and exit
  -v, --version         display current version of Hashy
  -hf MD5:SHA1:blake2b [MD5:SHA1:blake2b ...]
                        the required hash function.
  -cf <file path> <file path>
                        check hash of two files for a match using the provided
                        hash function.
  -f <file path>        calculate hash for a file using the provided hash
                        function.
  -s "String"           calculate hash for a string using the provided hash
                        function (string inside " " is recommended).

• -hf is essential for the script to run
• -cf / -f / -s : only one of the previous arguments followed by the appropriate input is required to run the script.

Test

Tested with a string being hashed with md5,sha1 and sha256 algorithms:

C:\Users\<current user>\Desktop> python hashy.py -hf md5 sha1 sha256 -s "hello world it's hashy here" 
Hashing string ...

Algorithm:         Hash value:
------------       --------------------------------------
md5                ba672a8326b0d3333c7296e73e0ec0ed
sha1               2e561e67dfe68f64d63204c7e96f0dccaec5cb00
sha256             eb43f53ec1b2d25c0361574e99b4257a5a84d123f7e265e0434e03789276d460
