FXOR (File XOR)

XOR files and safely save them in server storage. Interacting with Malicious file may cause many problems in your server/system. The FXOR can help you write and read files byte by byte changing data with XOR operator and provided as a IO Base class.

Know More About FXOR

To use fxor you need to understand basic of it. first of all you need some arguments :

1. An integer key in range(0, 256)
2. Path to a file
3. File open mode w for write mode or r for read mode
4. Fast mode for True or False which effects writing speed and memory usage
5. File real name or even None

Now let's see what does each one of these arguments do:

• key is used for XOR operation and you need same key for reading a file XORed with that key.
• Path to a file or XORed file in read mode
• Open mode
• Fast mode which can use more RAM if you set it to True
• File name if you need to use.

Usage :

Import into your project :

from fxor import FileXOR

chunk_size = 1024 * 1024 # 1 MB

# Write/Create new file
with FileXOR(8, "path/to/output_file", "w", True, "output_file") as f:
    with open("path/to/input_file", "rb") as f2:
        while True:
            data = f2.read(chunk_size)
            f.update_write(data)
            if len(data) < chunk_size:
                break

# Read from XORed file
with FileXOR(8, "path/to/input_file", "r", True, "input_file") as f:
    with open("path/to/output_file", "wb") as f2:
        while True:
            data = f.read(chunk_size)
            f2.write(data)
            if len(data) < chunk_size:
                break

Use Command Line Interface

python3 fxor.py "1.jpg" "2.enc" 8 "w"

python3 fxor.py "2.enc" "2.jpg" 8 "r"

Here is the arguments we passed :

1. File name to open
2. File name to write to
3. The key
4. File open mode
