About XOR Cipher
XOR (Exclusive OR) cipher is a simple encryption algorithm that combines each character of the plaintext with a character from a key using the XOR operation.
Symmetric: The same operation is used for both encryption and decryption. To decrypt, simply apply XOR with the same key again.
Security: XOR cipher is not secure for modern cryptographic needs. It's mainly used for educational purposes and simple obfuscation.
Key length: The key is repeated cyclically if it's shorter than the input text. Longer keys provide better security.
