To brute-force the remaining part of the password based on the information provided, we can write a Python script to attempt all possible combinations of characters for the missing part.Python Script:

import hashlib import itertools

The known part of the password known_part = "Om@nYg"

The character set based on the given password policy characters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789*@%^+_"

The target hash target_hash = "827d1057ad7258b180efca5e9cc25795a1a5f622"

Brute-force to find the remaining part of the password def find_password(known_part, target_hash, characters): # Try all combinations of 0, 1, 2, or 3 characters (since max password length is 9) for length in range(0, 4): # 0 to 3 remaining characters for combo in itertools.product(characters, repeat=length): # Build the complete password password = known_part + ''.join(combo) # Compute its SHA-1 hash hashed_password = hashlib.sha1(password.encode()).hexdigest() # Check if it matches the target hash if hashed_password == target_hash: return password return None

Find and print the password password = find_password(known_part, target_hash, characters) if password: print(f"The password is: {password}") else: print("Password not found.")

Explanation:

Known Part: We know that the password starts with "Om@nYg".2.3.2.3.4.
