I've started to write a key file in python with all potential keys but the file size is too large and I think fiji's CW finder program can't use it.

Could you share your code for that ?

Also dose anyone know of a python method to produce the crypt8 from a known CW ?

Thanks to all for sharing your files here (y)

This python code creates a lot of large txt files with all CW combinations.

import os

def create_large_hex_file(directory="C:/hex_files/", max_file_size=8 * 1024**3): # max_file_size = 8 * 1024**3, where 8 = it creates txt files with 8 GB file size, you can modify it
os.makedirs(directory, exist_ok=True)
max_value = int("F" * 12, 16)

file_index = 0
current_file_size = 0
file = open(f"{directory}/hex_part_{file_index:06d}.txt", "w")

for i in range(max_value + 1):
line = f"{i:012X}\n"
line_size = len(line.encode("utf-8"))

if current_file_size + line_size > max_file_size:
file.close()
file_index += 1
current_file_size = 0
file = open(f"{directory}/hex_part_{file_index:06d}.txt", "w")

file.write(line)
current_file_size += line_size

file.close()
print(f"Total {file_index + 1} file(s) created.")

# run:
create_large_hex_file()

Wait, you try to make 000000000000 - FFFFFFFFFFFFFFFF or 8GB random keys?
in case of the former, just don't...

Hi! any update on the new txt file?

I've also created a Python script that will help me on finding ATP feed keys on Apstar 7, sometimes their feed doesn't send Crypt8 and I notice that their key is always patterned into 4 numbers, 4 letters and 4 numbers again

Python: 
import itertools
import os
import time
from tqdm import tqdm  # Install with: pip install tqdm

def calculate_file_size():
    digits = '123456789'
    letters = 'ABCD'

    # Calculate the number of strings
    num_strings = (len(digits) ** 4) * (len(letters) ** 4) * (len(digits) ** 4)

    # Each string is 12 characters + 2 newline characters
    bytes_per_string = 12 + 2
    total_bytes = num_strings * bytes_per_string

    # Convert bytes to GB
    file_size_gb = total_bytes / (1024 ** 3)

    print(f"Expected file size: {file_size_gb:.2f} GB")
    return num_strings, total_bytes

def format_time(seconds):
    """Convert seconds into HH:MM:SS format."""
    hours = int(seconds // 3600)
    minutes = int((seconds % 3600) // 60)
    seconds = int(seconds % 60)
    return f"{hours:02}:{minutes:02}:{seconds:02}"

def generate_strings():
    digits = '123456789'
    letters = 'ABCD'
    file_name = 'atp.txt'

    # Check if file exists
    if os.path.exists(file_name):
        user_input = input(f"Warning: {file_name} already exists. Overwrite? (y/n): ").strip().lower()
        if user_input != 'y':
            print("Operation cancelled. No file changes made.")
            return

    # Calculate expected size
    total_strings, expected_size = calculate_file_size()

    # Start time tracking
    start_time = time.time()
    last_update_time = start_time

    # Generate and write strings with a progress bar
    with open(file_name, 'w') as f, tqdm(total=total_strings, unit='strings') as pbar:
        for first_four in itertools.product(digits, repeat=4):
            for middle_four in itertools.product(letters, repeat=4):
                for last_four in itertools.product(digits, repeat=4):
                    string = ''.join(first_four) + ''.join(middle_four) + ''.join(last_four)
                    f.write(string + '\n')

                    # Update progress
                    pbar.update(1)

                    # Refresh display every 1 second
                    if time.time() - last_update_time >= 1:
                        elapsed_time = time.time() - start_time
                        estimated_time_left = (
                            (elapsed_time / pbar.n) * (total_strings - pbar.n) if pbar.n > 0 else 0
                        )
                        pbar.set_postfix(time_left=format_time(estimated_time_left))
                        last_update_time = time.time()

    print("File generation complete.")

if __name__ == "__main__":
    generate_strings()

It will show the file size and progress when making it...
I wish cudabiss support this mode...

I'm not a programmer, could you change your code for keys which use year, months and days?
ABCDEF250505
AB05CDEF0505
AB25CD05EF05 and others
Year = 25
Month = 05
Day = 01 to 31

I've already tried it but it's not OK. So we could create keys for a month.

Sure! Give me the exact range of year, month and day you want

For the above, here's the code
Python: 
# Define the patterns
patterns = [
    "ABCDEF2505",
    "AB25CDEF05",
    "AB25CD05EF"
]

# Generate sequences
output_lines = []
for pattern in patterns:
    for i in range(1, 32):  # Decimal range 01-31
        output_lines.append(f"{pattern}{i:02d}")

# Write to a text file
output_file = "output.txt"
with open(output_file, "w") as file:
    file.write("\n".join(output_lines))

print(f"File '{output_file}' has been created successfully.")

I'd like to change the year and month only. So we can create keys for a month once.

Year = first two digits YY1 = 20, last two digits YY2 = 25
Month = 05 (MM)
Days = 01 to 31 (DD)
XX = 00 to FF (XX)

2025XX01XX05
..
XX25XX052001

I've tried this earlier but there are a lots of combinations.

# All possible formats (year is split into YY1 and YY2)
formats = [
"{YY1}{YY2}{DD}{MM}{XX}{XX}",
"{YY1}{DD}{MM}{XX}{YY2}{XX}", # Year first, then day, month, hex
"{DD}{XX}{MM}{YY1}{XX}{YY2}", # Day first, hex in between, year split
"{XX}{YY1}{DD}{MM}{YY2}{XX}", # Hex first, then year and date
"{XX}{YY2}{DD}{MM}{YY1}{XX}", # Hex first, reversed year order
"{DD}{MM}{YY1}{XX}{YY2}{XX}", # Standard date, split year, hex mixed
"{YY2}{XX}{DD}{YY1}{XX}{MM}", # Reversed year split, mixed hex
etc

A bit complicated, but doable...
So, you'll have 6 factorial (6!) = 720 combination of formats from the 6 variables (yy1, yy2, mm, dd, hex1, hex2)

Then 31 days, 256 hexes

720 * 31 * 256 * 256 = 1.462.763.520 keys

I can try tonight...

What do you do in that case ? Are you simply trying keys until one works ......surely not ??

Asking my friend who use Starsat/GTMedia box to find the key, those box producer have servers that I believe finding keys by actually bruteforcing keys one by one.
This become increasingly common and used by many feed providers

A mate of mine has found that gtmedia sends and encrypted "ECM" request (i say ecm as it has the correct length to be one - it may not be). How this "ecm" is calculated or used on the server end - i have no idea - but results of a returned working CW are scary fast if it is indeed brute force......

Hmm... do you have the API link? is it HTTP?
