Explanation:
Detailed explanation-1: -The Enigma machines produced a polyalphabetic substitution cipher. During World War I, inventors in several countries realized that a purely random key sequence, containing no repetitive pattern, would, in principle, make a polyalphabetic substitution cipher unbreakable.
Detailed explanation-2: -The Enigma machine implemented a substitution cipher, which encrypts a message by substituting one character for another.
Detailed explanation-3: -In 1939, Operation Ultra charged cryptologists with breaking the Enigma code and devising a rapid means of transcribing the intercepts. The breaking of Enigma began even before the creation of the Bletchley Park cryptanalysis department.
