How to create Hash calculator Using Python


Hello guys, Today we will learn, how to create hash calculator using python with the help from hashlib module using Python.In my previous article, we was learnt about cryptographic hashes. Now we will be make a hash calculator.

Requirment:

Python Installed in your Operating System.

Step:

In my code, first import

  • import hashlib
  • import sys
  • import optparse


where hashlib module for hashing algorithm
sys module use for system fuction
and last one, optparse module use for command line options.

Full Source Code of How to create Hash calculator Using Python


import hashlib
import sys
import optparse


parser = optparse.OptionParser()
parser.add_option('-n', '--name', dest='name', help='''Your Algo Name Options:
                                                    md5,sha1,sha224,sha256,sha384,sha512''')
parser.add_option('-k', '--key', dest='key', help='Your string key value')

(options, args) = parser.parse_args()


list = ['md5','sha1','sha224','sha384','sha512']

    
if options.name is None:
    options.name = raw_input('Please enter right Algo Name: ')
    if options.name in list:
        print 'Ok'
    else:
        print 'You are choose wrong Algo Name'
        sys.exit()
        
if options.key is None:
    options.key = raw_input('Enter Your Key Value: ')
        

select = options.name 
data = options.key 

h = hashlib.new(select)
h.update(data)
print 'Your ' + select + ' hash value: ',h.hexdigest()


In above code save as “anyname.py” where “.py” our file extension.

When you run above program, Your Encode.txt Decode your origanal content and save as same location as Decode.txt.

How to Use:

Step:

Open your command prompt and change your directory path where our hash_calculator.py is store.

After that, type in your command prompt:


python hash_calculator.py -h


Usage: Python hash_calculator1.py [options]

Options:
  -h, --help            show this help message and exit
  -n NAME, --name=NAME  Your Algo Name Options:
                        md5,sha1,sha224,sha256,sha384,sha512
  -k KEY, --key=KEY     Your string key value

Or you can direct use of this program. Write below command in your command prompt :

 python hash_calculator.py       and hit enter

After that enter your right algo name for example md5.

After that write your string value which you want to convert in md5 algorithm.
