.. py:function:: running_key_decrypt(key: str, ciphertext: str) -> str

   Decrypts the ciphertext using the Running Key Cipher.

   :param key: The running key (long piece of text).
   :param ciphertext: The ciphertext to be decrypted.
   :return: The plaintext.


.. py:function:: running_key_encrypt(key: str, plaintext: str) -> str

   Encrypts the plaintext using the Running Key Cipher.

   :param key: The running key (long piece of text).
   :param plaintext: The plaintext to be encrypted.
   :return: The ciphertext.


.. py:function:: test_running_key_encrypt() -> None

   >>> key = "How does the duck know that? said Victor"
   >>> ciphertext = running_key_encrypt(key, "DEFEND THIS")
   >>> running_key_decrypt(key, ciphertext) == "DEFENDTHIS"
   True
