Description
Retrieve your encrypted message from the spreadsheet that will be shared by your instructor.
Complete each of the following:
Perform the initial decryption step by converting each value in your message from its given base 10 form to an equivalent converted string in congruence modulo 26. In other words, for each value A in the data, what is B such that A ≡ B (mod 26)? Show all of your converted values in a string, separated by spaces, in the same order as translated from the original data.
Describe and show how you carried out at least one of your congruence modulo 26 operations to determine the initial decrypted value.
Convert the initial decrypted string to alphabetic letters using the equivalence relation shown. Report the final message.
