Handycipher — Part 5 Level 3

by Bruce Kallick, published on 6/28/2016

Handycipher is a newly created cipher designed to permit pen-and-paper encrypting and decrypting, while providing a significantly high level of security. Part 5 is the same as Part 2, but uses an improved version of the cipher. You are given the ciphertext and 229 letters occuring at an unknown location in the plaintext.
