ZR-Cracker: Zip & Rar Password Recovery

ZR-Cracker is a tool designed for recovering lost passwords for ZIP and RAR files. It leverages Python libraries to systematically test passwords and determine if a given password is correct.

How to Check a ZIP File Password

The following function verifies if a password is correct for a ZIP file using the pyzipper library. If the password is incorrect, it throws a RuntimeError.


import pyzipper
import time

def check_zip_password(a, zip_path, password, start_time):
    try:
        with pyzipper.AESZipFile(zip_path, 'r') as zf:
            _ = zf.read(zf.namelist()[0], pwd=password.encode('utf-8'))
        total_time = time.time() - start_time
        print("===============================================")
        print(f"Total time taken ::: {total_time:.2f} seconds")
        print("Total password tries ::: {}".format(a))
        print("Password Found ::: {}".format(password))
        print("===============================================")
        return False
    except RuntimeError:
        return True
    except:
        time.sleep(4)

How to Check a RAR File Password

This function verifies if a password is correct for a RAR file using the rarfile library. If the password is incorrect, it throws a rarfile.BadRarFile exception.


import rarfile
import time

def check_rar_password(a, rar_path, password, start_time):
    with rarfile.RarFile(rar_path) as rf:
        try:
            rf.testrar(pwd=password.encode('utf-8'))
            total_time = time.time() - start_time
            print("===============================================")
            print(f"Total time taken ::: {total_time:.2f} seconds")
            print("Total password tries ::: {}".format(a))
            print("Password Found ::: {}".format(password))
            print("===============================================")
            return False
        except rarfile.BadRarFile:
            return True
        except:
            time.sleep(4)

How to Generate a Random Password

This function generates a random password between 4 and 11 characters using the secrets library. The password contains a mix of letters, numbers, and symbols.


import secrets
import string

def generate_random_password():
    length = secrets.choice(range(4, 11))
    characters = string.ascii_letters + string.digits + string.punctuation
    password = ''.join(secrets.choice(characters) for _ in range(length))
    return password

Protecting Your Files

While ZR-Cracker helps recover lost passwords, it's essential to implement strong security measures for protecting your compressed files:

Use Strong Passwords: Choose passwords with at least 12 characters, including letters, numbers, and symbols.
Enable Encryption: Encrypt ZIP and RAR files using AES-256 encryption for added security.
Backup Important Files: Store copies of critical files securely to prevent data loss.
Avoid Common Passwords: Do not use easily guessable passwords like "123456" or "password".
