    A MonoAlphabetic Substitution Cipher maps individual plaintext letters to individual ciphertext letters, on a 1-to-1 unique basis. That is, every instance of a given letter always maps to the same ciphertext letter. Here's the ciphertext for a message enciphered in the way described above (this is a shift substitution cipher): Kyzj vetipgkzfe dvkyfu nrj ljvu sp Ifdrej ze Tvrjri'j nrij. What is the plaintext for this message? Given the approach described above, for a Shift Substitution Cipher, how many possibilities are there for a shift value? Is this a feasible task? Given the approach described above, for a MonoAlphabetic Substitution cipher, how many possibilities are there for character mappings? Is this a feasible task?
