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.
