looking for cracking classic ciphers
Budget: $10 – $30 USD
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?
What would you expect to happen in this case?
