файл: "decode_10_4"
робот-курьер "Коммунар" доставил закодированное послание из центрального узла. данные представлены в формате Base32 для передачи через старые системы связи и, похоже, закодированы не один раз. видимо, одной кодировки оказалось мало-схему усложнили. ваша задача-извлечь секретную информацию.

Checking for uploaded file

I need to check if the file "decode_10_4" was uploaded. The user seems to want to decode Base32 multiple times to extract secret info. Since no file is explicitly mentioned yet, I’ll list files in the working directory and look for this file by name, with or without extension.

Decoding Base32 repeatedly

Once I locate the file, I need to check if it’s Base32 encoded. I’ll attempt decoding multiple times, stopping when it stops making sense (e.g., when the result is readable ASCII text). I’ll be careful to handle any uppercase, lowercase, or whitespace characters without damaging the data, using a method to decode Base32.

Handling multiple decodings

I need to handle cases where Base32 decoding fails by using a loop with try-except. If the result is still Base32 encoded, I’ll decode again. I'll stop when decoding fails or no data change happens. I should also check for other encodings (like gzip) or compressed data and output the final message, maybe saving it in a file.

Creating a decoding report

I'll go ahead and create a report with all decoding steps included. We need to do everything in one go since I can’t promise later updates. I'll proceed with a Python script to list files, read the specified file, decode it iteratively, and log the steps. The response will be in Russian to match the user's message.

Decoding procedure outline

I’ll start by reading the file as bytes and decoding it to a string using ASCII/UTF-8. After cleaning up the string (removing extra whitespace and handling case differences), I’ll attempt Base32 decoding multiple times, logging each step. When the process is done, I'll check if the content can be saved as a file or

Handling missing file

I can't find the file "decode_10_4" that the user mentioned, so I’ll acknowledge that. Instead of asking clarifying questions, I'll provide a template Python script for the user to run once they supply the file or Base32 data. The script will handle iterative Base32 decoding and extracting secret information.

Acknowledge missing file

I couldn't find the file the user mentioned ("decode_10_4"). Instead of asking for clarification, I'll acknowledge the issue and suggest that they either upload the file or paste its contents. Since they suggested using Python, I’ll provide a ready-to-run script for Base32 decoding.

Request for file or contents

It looks like we're missing the file "decode_10_4." To move forward, I'll ask the user to upload the file or paste its contents. I'll provide a simple decoder in Python for when that happens. I'll also give them an option to paste a Base32 block for immediate decoding here.

Request for file or input

It looks like the file "decode_10_4" isn’t available. I searched for it, but found nothing. To move forward, you could either upload the file or paste its contents here. I’ll provide a Python code snippet that handles multiple Base32 layers and also trims whitespace and mixed case.

Классная задачка! Я готов её раскалывать, но у меня нет самого файла — decode_10_4 не найден среди загруженных в сессию. Чтобы я сразу извлёк секрет, сделайте одно из двух:

  1. Загрузите файл сюда (любой формат/расширение с этим именем ок),
    или
  2. Вставьте содержимое (весь Base32-блок) в сообщении в тройных кавычках:
<сюда вставьте весь зашифрованный текст>

Я моментально прогоню через итеративную декодировку Base32 и верну итог.

Если хотите проверить локально — вот минимальный скрипт Python, который декодирует Base32 «до упора» (игнорирует переводы строк/пробелы и регистр) и пытается вывести итог как текст; если текстом не получилось — сохранит сырые байты:

python
import sys, re, base64, binascii, pathlib

# Чтение из stdin (удобно: python b32decode.py < decode_10_4)
raw = sys.stdin.buffer.read()
cur = re.sub(rb"\s+", b"", raw)  # убрать пробелы/переносы

iters = 0
while True:
    try:
        cur = base64.b32decode(cur, casefold=True)
        iters += 1
    except binascii.Error:
        break

# Печатаем сводку в stderr
print(f"[i] Base32 раскодировано итераций: {iters}", file=sys.stderr)
print(f"[i] Итоговый размер: {len(cur)} байт", file=sys.stderr)

# Пытаемся показать как UTF-8, иначе пишем raw в файл
try:
    txt = cur.decode("utf-8")
    print(txt)
except UnicodeDecodeError:
    out = pathlib.Path("decode_10_4_final.bin")
    out.write_bytes(cur)
    print(f"[i] Итог не похож на UTF-8; записал байты в {out}", file=sys.stderr)

Готов продолжить — пришлите саму строку/файл, и я извлеку секрет прямо тут.
