As part of that effort, the Poles exploited quirks of the rotors, compiled catalogues, built a cyclometer to help make a catalogue with 100,000 entries, made Zygalski sheets and built the electro-mechanical cryptologic bomb to search for rotor settings.
The Poles had six bomby, but when the Germans added two more rotors, ten times as many bomby were needed, but the Poles did not have the resources.in Pyry near Warsaw, the Poles initiated French and British military intelligence representatives into their Enigma-decryption techniques and equipment, including Zygalski sheets and the cryptologic bomb, and promised each delegation a Polish-reconstructed Enigma.On the sides of the rotors are a series of electrical contacts that, after rotation, line up with contacts on the other rotors or fixed wiring on either end of the spindle.When the rotors are properly aligned, each key on the keyboard is connected to a unique electrical pathway through the series of contacts and internal wiring.Any proposed explanation should therefore not only bridge the century-long historical gap, but also demonstrate why the VMs appears both ‘language-y’ and ‘cipher-y’ at the same time. From a code-breaker’s point of view, this basically rules out Renaissance polyalphabetic ciphers, because they use multiple alphabets (or offsets into alphabets) to destroy the outward signs of internal structure – and what we see here has even more signs of internal structure than normal languages.
To illustrate this, here are some practical examples of the way Voynichese letters ‘dance’ to a tricky set of structural rules. Yet just to be confusing, some of the letter-shapes resemble shorthand both in their shape and their apparent positioning within words. is ‘Voynichese’ a language, a shorthand, a cipher, or perhaps some carefully-orchestrated jumble of all three?
Furthermore, I suspect taht some of the ‘chicken scratch’ marginalia may be ink blots saying “Simon”, and that these were added in the middle of the 15th century, near the start of the VMs’ life. Putting all the wobbly factuality to one side, this VMs account would be woefully incomplete if it failed to mention the sheer intellectual romance of such a mystery-filled mega-object, the tragi-comedy of all the mad theories surrounding it, let alone the blood-spattered trail of ruined reputations and wasted lives dripping behind this inscrutable “Sphinx”.
For centuries, it has acted as a blank screen for numerous people to project their (often somewhat demented) historical / cryptological / novelistic fantasies onto, or if not that then an academic cliff to throw their hard-earned reputation over: yet recently there are signs that a few people are (at long last) starting to look at the VMs with (relatively) clear eyes. ) Arguably the biggest question to face up to is this: when people try to understand the VMs, ).
The demonstration represented a vital basis for the later British continuation and effort.
During the war, British cryptologists decrypted a vast number of messages enciphered on Enigma.
