These solutions may offer step-by-step problem-solving explanations or good writing examples that include modern styles of formatting and construction of bibliographies out of text citations and references. Students may use these solutions for personal skill-building and practice. Unethical use is strictly forbidden.As methodology, I have used a combination of techniques based on cryptanalysis, brute-force for chunks of it, cryptographic tools, and code snippets.
Namely, since Aristocrat is a monoalphabetic substitution cipher, it is vulnerable to cryptanalysis which uses the frequency of symbols’ distribution (i.e. the frequency of letters from plain English is preserved in the ciphertext). This is how, based on the counting, since E and X are the most used symbols in the ciphertext and it is unlikely for E to map to itself, given that E is the most used letter in English words, I attempted with X being the encryption of E from the plaintext.
Besides the frequency distribution of single letters, I have also looked at the digrams and trigrams, but also tried to identify repeating patterns (e.g. OEH) and then matched according to their distribution in plain English....
