Info
ReverseBox is a Python package with a set of functions useful in software reverse engineering.
Why ReverseBox?
It's designed to help with:
- Decompressing / compressing data
- Decrypting / encrypting data
- Tedious reverse engineering tasks e.g. testing different checksum algorithms to find the one that was used in the software or file format
- Figuring out file formats
- Parsing data structures
- Wrapping functions for input/output operations
- Searching for raw images
Who should use ReverseBox?
Mostly developers and reverse engineers (e.g. file format researchers
or software researchers).

Checksum calculation - example
// CRC32 calculation
from reversebox.crc import crc32_iso_hdlc
from reversebox.common import common
test_data = b'123456789'
crc32_handler = crc32_iso_hdlc.CRC32Handler()
crc32 = crc32_handler.calculate_crc32(test_data)
print("CRC32_INT: ", crc32)
print("CRC32_STR: ", common.convert_int_to_hex_string(crc32))
// CRC32 output
CRC32_INT: 3421780262
CRC32_STR: 0xCBF43926
XOR encryption - example
// XOR Cipher (Basic)
from reversebox.encryption.encryption_xor_basic import xor_cipher_basic
test_data = b'abcd'
test_key = b'\x3D'
xor_result = xor_cipher_basic(test_data, test_key)
print(xor_result)
// XOR Cipher output
b'\\_^Y'
File Handler - example
// File reading
import os
from reversebox.io_files.file_handler import FileHandler
file_path = os.path.join(os.path.dirname(__file__), "file.bin")
file_reader = FileHandler(file_path, "rb")
file_reader.open()
value = file_reader.read_str(4, "utf8")
print(value)
// File Reader Output
ABCD
Hash calculation - example
// SHA-1 calculation
from reversebox.hash.hash_sha1 import SHA1Handler
test_data = b'abcd'
sha1_handler = SHA1Handler()
sha1 = sha1_handler.calculate_sha1_hash(test_data)
print("SHA-1 hash: ", sha1)
// SHA-1 Output
SHA-1 hash: b'\x81\xfe\x8b\xfe\x87Wl>\xcb"Bo\x8eW\x84s\x82\x91z\xcf'
Image decoding - example
// DXT1 compressed image decoding
from reversebox.image.image_decoder import ImageDecoder
from reversebox.image.image_formats import ImageFormats
from reversebox.image.pillow_wrapper import PillowWrapper
def show_img():
with open("image_data_dxt1_64x64.bin", "rb") as f:
image_data = f.read()
img_width: int = 64
img_height: int = 64
decoder = ImageDecoder()
wrapper = PillowWrapper()
converted_data: bytes = decoder.decode_compressed_image(image_data, img_width, img_height, ImageFormats.BC1_DXT1)
pil_image = wrapper.get_pillow_image_from_rgba8888_data(converted_data, img_width, img_height)
pil_image.show()
if __name__ == '__main__':
show_img()
