XOR Encryption/Decryption

This project demonstrates a simple XOR cipher for encoding and decoding text. XOR encryption is a symmetric key encryption technique where the same key is used for both encryption and decryption.

Files

• xor_encoder.py: Script for encoding text using the XOR cipher.
• xor_decoder.py: Script for decoding text using the XOR cipher.

Usage

Encoding

1. Run the encoder script:

   python xor_encoder.py

2. Enter the text you want to encode.
3. Enter the encryption key (an integer).

The script will output the encoded text.

Decoding

1. Run the decoder script:

   python xor_decoder.py

2. Enter the text you want to decode.
3. Enter the decryption key (an integer).

The script will output the decoded text.

Example

Encoding Example

$ python xor_encoder.py
Enter the text to encode: Hello, World!
Enter the encryption key (integer): 123
Encoded text: ϮϢϢϩϧϧϧϢϧϯϧϦϨϢ

Decoding Example

$ python xor_decoder.py
Enter the text to decode: ϮϢϢϩϧϧϧϢϧϯϧϦϨϢ
Enter the decryption key (integer): 123
Decoded text: Hello, World!
