Breaking SHA-1 Hashes with Python: A Beginner’s Guide to Hash Cracking

 GitHub: https://github.com/AdithyakrishnaV/Python-for-Penetration-Testing/blob/master/SHA-1_PASSWORD_CRACKER.py

hashing is a one-way function. So we cannot reverse the hash we can only Brute-force it and check for a similar hash

import hashlib

This line imports the hashlib library, which provides implementations of various hash functions.

def hashing(check,word):

This line defines a function called hashing that takes two parameters: check and word

for w in word:

This line sets up a loop that iterates over each word in the word list.

hasher=hashlib.sha1(w.encode())

This line uses the SHA1 algorithm from the hashlib library to hash the current w word in the loop. It first encodes the word as bytes using the encode() method.

c=hasher.hexdigest()

This line extracts the resulting hash from the hasher object and converts it to a string of hexadecimal digits using the hexdigest() method.

if(str(c)==check):

This line checks whether the resulting hash string matches the check parameter. It converts the hash string to a regular string using str() to ensure the comparison is done correctly.

print("\n"+w+"\n")
            break

If there is a match, this line prints the matching word and breaks out of the loop. The \n characters create a new line before and after the word for better readability.

else:
            print("no")

If there is no match, this line prints "no".

f= open("pass.txt", "r") 
word=f.read().split()

This line opens the file pass.txt in read mode, reads its contents into a string, and splits the string into a list of words. The word variable is set to this list.

check=input("Enter the hash: \n ")

This line prompts the user to enter a hash to check against.

hashing(check,word)

This line calls the hashing function with the check and word parameters.

f.close()

This line closes the pass.txt file

Another way:

But this is not fast if we have a big list of words then let’s make it faster the next time may be using RUST
