Handycipher — Part 8 Level 3

by Bruce Kallick, published on 1/21/2017

Handycipher is a newly created cipher designed to permit pen-and-paper encrypting and decrypting, while providing a significantly high level of security. Part 8 is the same as Part 5, but uses an improved version of the cipher. You are given the ciphertext and 229 letters occuring at an unknown location in the plaintext.
