Dcode

A little helper app for macOS to interactively decipher cipher texts. Implemented along the HWS+ live stream by Paul Hudson.

Supports you in deciphering the following "simple" ciphers:

Caesar
Columnar (a transposition cipher)
Vigenère

The implementation shows

simple SwiftUI macOS app implementing above ciphers
distance analysis and frequency analysis in Swift
use of Swift Algorithms package:
- chunk data using chunks(ofCount:)
- windowing using windows(ofCount:)
- uniquing using uniqued()
- striding using striding(by:)

You can find some cipher texts in the Examples folder.
