Python Secret #Author: ManishHacker1

Hello guys, Today we will learn, how to create hash calculator 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


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.

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.

Thank You for reading this article. And like my FB page givin below link and share it.

How to Connect Window Machine to Linux Machine Using Python via SSH

By
Python Secret #Author: ManishHacker1 Hello everyone, This is my another article about SSH connectivity to the client machine. In my previous article we have some trouble using pxssh module on windows machine. That's why I am writing another article for the SSH connection. In this article we will use paramiko module to connect another machine. This is fully supported windows, Mac and Linux machine users. In this article, I will show you how to use Paramiko SSH (a Python SSH library) to connect and gather information from another Machine. What is Paramiko? Paramiko is a Python (2.6+, 3.3+) implementation of the SSHv2 protocol [1], providing both client and server functionality. While it leverages a Python C extension for low level cryptography (Cryptography), Paramiko itself is a pure Python interface around SSH networking concepts.

How to Create MD5 Brute Force Script Using Python

By
Python Secret #Author: ManishHacker1 How to Create MD5 Brute Force Script Using Python Hello guys, Today we will be learn How to create MD5 brute force script using Python. What is brute-force Attack? Brute-force attack also known exhaustive key search Process of checking all possible keys Using a dictionary to attack with Dictionary is usually more effective than searching the whole key space. Exponentially grow with increasing key size. Brute force Attack Limit Because time/energy required to crack a key grows exponentially with key size, encryption in today's standards and computing power are safe brute-force attack. A 256 bit key would take on 50 of today's super computer 3x10^51 years What is Dictionary Attack Much faster than a whole key space search Not guaranteed Commonaly used on passwords Dictionaries can be found online A popular one is darkc0de.lst Good to run before a big dictionary like darkc0de. Can eliminate the most com...
