Weakened Handycipher — Part 4 Level 2

by Bruce Kallick, published on 6/28/2016

The Weakened Handycipher challenges serve as an exercise and use an intentionally weakened version of Handycipher. Part 4 is the same as Part 1, but uses an improved version of the cipher. You are given the first 1,009 characters of the plaintext, and some partial information about the key.
