This is a genetic algorithm for breaking monoalphabetic cipher I completed as part of a challenge. I have had to update it to recent Swift syntax so it would compile correctly - I apologise for any ...

Welcome to the Monoalphabetic Cipher Breaker project! This project aims to decrypt text encoded using a monoalphabetic cipher. We achieve this using a genetic algorithm that searches for the best ...

The monoalphabetic substitution cipher encrypts a given text by replacing every letter in the text with a different letter according to some predefined scheme. The cryptanalysis of this cipher ...

As long as one knows the enciphering algorithm, this well-known cipher could indeed be solvable, and one of the biggest mysteries of its time could finally be cracked.
