Handycipher is a newly created cipher designed to permit pen-and-paper encrypting and decrypting, while providing a significantly high level of security. Part 7 is the same as Part 4, but uses an improved version of the cipher. You are given the ciphertext and the first 229 letters of the plaintext.
