JCrypTool is a Windows educational platform designed to help users study cryptography. The main GUI is clear and intuitive, making it easier to explore data protection concepts with minimal prior knowledge.

Interactive learning environment

Similar to CrypTool, you can begin a new project by creating an empty text document or importing an existing file containing any information. The next step is to select the desired cryptographic algorithm such as:

ElGamal;
Autokey Vigenere;
SHA 256;
DSA, etc.

It is possible to visualize underlying processes such as key generation, data scrambling workflows and value transformations. This enables users to better understand complex encryption mechanics.

Other functions

There are instruments for conducting frequency and entropy analysis, which may be crucial when processing large datasets. Additionally, you are able to apply advanced deciphering algorithms to reveal text protected via simple column transposition.

Several mini games like Divider, Number Shark and Zudo Ku are included. They are intended to help students grasp various cryptographic concepts in an entertaining way.
