    An Archeology of Cryptography: Rewriting Plaintext, Encryption, and Ciphertext

    An Archeology of Cryptography: Rewriting Plaintext, Encryption, and Ciphertext By Isaac Quinn DuPont A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Faculty of Information University of Toronto © Copyright by Isaac Quinn DuPont 2017 ii An Archeology of Cryptography: Rewriting Plaintext, Encryption, and Ciphertext Isaac Quinn DuPont Doctor of Philosophy Faculty of Information University of Toronto 2017 Abstract Tis dissertation is an archeological study of cryptography. It questions the validity of thinking about cryptography in familiar, instrumentalist terms, and instead reveals the ways that cryptography can been understood as writing, media, and computation. In this dissertation, I ofer a critique of the prevailing views of cryptography by tracing a number of long overlooked themes in its history, including the development of artifcial languages, machine translation, media, code, notation, silence, and order. Using an archeological method, I detail historical conditions of possibility and the technical a priori of cryptography. Te conditions of possibility are explored in three parts, where I rhetorically rewrite the conventional terms of art, namely, plaintext, encryption, and ciphertext. I argue that plaintext has historically been understood as kind of inscription or form of writing, and has been associated with the development of artifcial languages, and used to analyze and investigate the natural world. I argue that the technical a priori of plaintext, encryption, and ciphertext is constitutive of the syntactic iii and semantic properties detailed in Nelson Goodman’s theory of notation, as described in his Languages of Art. I argue that encryption (and its reverse, decryption) are deterministic modes of transcription, which have historically been thought of as the medium between plaintext and ciphertext.

  • Enigma Sim Manual

    Enigma Sim Manual

    ENIGMA SIM MANUAL About the Enigma Sim The program is an exact simulation of the 3-rotor Wehrmacht & Luftwaffe, the 3-rotor Kriegsmarine M3, and the famous 4-rotor Kriegsmarine M4 model of the German Enigma cipher machine, as they were used during World War II from 1939 until 1945. You can select between the three models, choose different rotors or 'Walzen', preset the rotor wiring positions or 'Ringstellung' and switch letters by using plugs or 'Stecker'. The internal wiring of all rotors is identical to those used by the Wehrmacht, Luftwaffe and Kriegsmarine. This simulator is therefore fully compatible with the real Enigma-machine and you can decipher original messages and encipher your own messages. This manual explains how to use the Enigma simulator, describes the message procedures as used by the German Armed Forces, a complete technical description and a brief history of the Enigma.
