Question

Write a Python function named ‘genreate_sha256’ that generates all possible 7-digit pin and the corresponding sha256 hash values and saves it into a file named ‘rainbow.csv’

Answer 1

import hashlib 
import csv 

filename = "rainboww.csv"
fields = ['7digit_pin','hash_value']
with open(filename, 'w') as csvfile:  
    
 csvwriter = csv.writer(csvfile)
 csvwriter.writerow(fields) 
 for i in range(1000000, 9999999):
    arr = []
    arr.append(i)
    result = hashlib.sha256(str(i).encode()) 
    print(i)
    print(result.hexdigest()) 
    arr.append(result.hexdigest())
    csvwriter.writerow(arr) 

since the size of generated hash value file is 666 mb i couldnt upload the file.
