List of implemented ciphers

= Ciphers with possibility to crack without a key. Some work, some work sometimes and others don't!

Licence information and other tributes

Where relevant the ciphers have the licence information included in the cipher information popup window. All of the code is adapted from open source implementations of cipers and converted to c# or written from scratch.

Things to do. Kanskje de kommer kanskje ikke!

02.07.2019 Added What3Words encoding and decoding
10.04.2019 Moved off Microsoft Azure to Loopia and added https:
10.04.2019 Upgraded platform to MS VS2019
31.03.2019 Added Facebook links and buttons
31.03.2019 Fix a bug on the Start Playing! button that had stopped working
28.10.2018 Added Trithemius, Alberti, Pollux, Larrabee and Polybius ciphers
20.10.2018 Upgraded platform to MS VS2017 (so it might be broken somewhere!)
14.10.2018 Corrected error with Keyed Alphabet creation using wrong alphabets
26.09.2018 Added Cookie Consent code to comply with GDPR
