Question

Guessing one password: write a function called guess that takes a string (a guessed password) as an argument and prints out matching information if its encrypted string matches any of the strings in the encrypted password file. When you write the function, you may hardcode the name of the password file.

Here is an example run:

   >>> guess("blue")
   Found match: blue
   Line number: 1
   Encrypted value: 16477688c0e00699c6cfa4497a3612d7e83c532062b64b250fed8908128ed548

You will want to use the encrypt function presented in class:

import hashlib

def greeting(uname):
greet_message = "Hey there " + uname + "!"
return greet_message

def longest(word_list):
'''returns the longest word in word_list,
the first if there are several'''

longest_so_far = ""
for word in word_list:
if len(word) > len(longest_so_far):
longest_so_far = word
return longest_so_far

def encrypt(password):
encrypted_pwd = hashlib.sha256(password.encode()).hexdigest()
return encrypted_pwd

Answer 1

Code:

1 import sys 2 import os 3 import hashlib 4 def encrypt(password): encrypted_pwd hashlib.sha256 (password.encode()).hexdigest() return encrypted_pwd 8 def guess (password): encryptedPass-encrypt (password) filepath./test.txt' with open(filepath) as fp: 10 12 for cnt, line in enumerate(fp): if line (encryptedPass+'n'): print( 'Found match: .format (password)) print ('Line number: .format(cnt+1)) print('Encrypted value: .format (line)) 13 14 15 16 17 18 19 def main(): 20 21 print("Enter guess") guessStr-raw_input() guess (guessStr) 23 24 if_name_--' main ': 25 main()

Sample output:

Content of test.txt file:

16477688c0e00699c6cfa4497a3612d7e83c532062b64b250fed8908128ed548
