Python 2暴力破解Super开头+3字母密码的Zip文件：代码无报错失效

Hey there! Let's try to figure out why your zip cracking/extraction code isn't working—especially since it's not throwing errors, which can be tricky. First off, could you share the code you've written so far? That'll make it way easier to spot exactly where things might be going wrong.

In the meantime, here are some common pitfalls to check for when dealing with password-protected zips, especially when brute-forcing a pattern like SuperXXX (XXX being 3 letters):

1. Incorrect Zip Library Usage #

Make sure you're using a library that actually supports password-protected zips properly. For example, Python's built-in zipfile module can handle AES encryption only in Python 3.11+, and older versions might silently fail if the zip uses strong encryption. If you're using zipfile, double-check:

• You're using ZipFile.setpassword() correctly (note: this only handles traditional Zip 2.0 encryption, not AES).
• For AES, you might need a third-party library like pyzipper instead.

2. Brute-force Loop Issues #

Since your password pattern is Super + 3 letters, your loop should generate all combinations of 3 lowercase/uppercase letters? Wait—did you account for case sensitivity? Zip passwords are often case-sensitive, so if you're only generating lowercase, but the actual password has uppercase letters, that's a problem.

Here's a quick example snippet using pyzipper that handles AES and generates the correct password combinations:

import pyzipper
import itertools

zip_file_path = "your_file.zip"
prefix = "Super"
# Generate all 3-letter combinations (lowercase + uppercase—adjust if needed)
chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"

for combo in itertools.product(chars, repeat=3):
    password = prefix + ''.join(combo)
    try:
        with pyzipper.AESZipFile(zip_file_path) as zf:
            zf.setpassword(password.encode('utf-8'))
            # Try extracting a single file first to save time
            zf.extract(zf.namelist()[0])
            print(f"Found password: {password}")
            # Extract all files once password is found
            zf.extractall()
            break
    except (pyzipper.BadZipFile, pyzipper.LargeZipFile, RuntimeError):
        # Wrong password, keep going
        continue

3. Silent Failures Due to Unhandled Exceptions #

If your code is catching exceptions too broadly (like a bare except:), it might be swallowing errors that would tell you what's wrong. For example, if the zip file is corrupted, or the library can't read it, a bare except would hide that. Always catch specific exceptions so you can see actual issues when they arise.

4. File Path Issues #

Double-check that the path to your zip file is correct. If the code can't find the file, but you're not checking for that, it might just loop infinitely without doing anything. Add a check to make sure the file exists before proceeding:

import os
if not os.path.exists(zip_file_path):
    print("Zip file not found!")
    exit()

Once you share your code, we can dive deeper into exactly what's going on. Let me know!
