The Portal of Historical Ciphers is an online portal consisting of several web pages and tools. Some of them are logically divided into modules. Each module represents a specific topic related to historical cryptology.
Nomenclator module (under development) consist of online tools designed to create, use, and share nomenclator cipher keys. This module also contains an online database of digitized cipher keys with a public API.
Education module (under development) contains a demonstration of some classical ciphers and their respective cryptanalytic techniques. Each technique is accompanied by a visualization.
Virtual museum of historical ciphers is built on a virtual reality framework supported by modern web browsers. The goal is to promote public interest in ciphers using modern technologies.
The portal features a special Database of cryptograms, containing a collection of cryptograms.
ManuLab (ManuLab Qt, Manulab API, ManuLab Online) is a software product for statistical analysis.
For more information read the articles published in the Proceedings of the 3rd and 4th International Conference on Historical Cryptology (documentation section).
The first version of the portal was developed from 2016. The content of the portal was gradually expanded. When designing new components, we focused exclusively on online accessible applications.
We support free access to information. Our database of cryptograms and database cipher keys are accessible with public API. For more information read the online documentation: cryptograms API, cipher keys API.
