RubyConf 2023 - The Unbreakable Code Whose Breaking Won WWII by Aji Slater

Discover how the Enigma machine, a complex system used to encrypt and decrypt messages during WWII, can be simplified and abstracted to understand its behavior, and how its principles can be applied to object-oriented programming using Ruby.

Key takeaways

Enigma machine is a polyalphabetic cipher with a new key every letter based on the starting position of the rotors.
The machine uses three rotors with 26 positions each, and a reflector, to encrypt and decrypt messages.
The rotors are internal to the machine and are not directly accessible from the outside.
The machine uses a lamp board to display the encrypted message.
The Enigma machine is a complex system with many moving parts, but it can be simplified and abstracted to understand its behavior.
The machine uses a combination of substitution and permutation to encrypt and decrypt messages.
The Enigma machine is a great example of object-oriented programming principles, such as encapsulation, abstraction, and dependency inversion.
The machine’s behavior can be tested and verified using a test-driven development approach.
The Enigma machine is a complex system that can be broken down into smaller, more manageable parts, and each part can be tested and verified individually.
The machine’s behavior can be simulated and tested using a programming language, such as Ruby.
The Enigma machine is a great example of how complex systems can be broken down into smaller, more manageable parts, and each part can be tested and verified individually.
The machine’s behavior can be tested and verified using a test-driven development approach.
