   cd rc4_tool

2. Install the required packages:

   pip install -r requirements.txt

Usage

Encryption

Encrypt a file using the RC4 algorithm.

python main.py your_key input_file output_file --encrypt

Decryption

Decrypt a file using the RC4 algorithm.

python main.py your_key input_file output_file --decrypt

Example

To encrypt a file named plaintext.txt with the key mysecretkey and save the result to ciphertext.txt:

python main.py mysecretkey plaintext.txt ciphertext.txt --encrypt

To decrypt the file ciphertext.txt with the same key and save the result to decrypted.txt:

python main.py mysecretkey ciphertext.txt decrypted.txt --decrypt
