In December 2021 we released "CrypTool 2 – 2021.2", the second release this year. The last CrypTool 2 release was published in May 2021.
Probably the most interesting new implementation of CrypTool 2 is the blockchain simulation. With the blockchain component and its templates, you can simulate a blockchain. The blockchain simulation allows you to create blocks, transactions, addresses and corresponding digital signatures.
Also worth mentioning is the official CrypTool 2 YouTube channel "Cryptography for everybody", which in December 2021 already had 3100 subscribers. Thank you at this point! For everyone who has not yet seen the channel: We discuss and explain cryptological topics and show many examples with CrypTool 2 and the other CrypTool implementations of the project (see Cryptography for everybody).
Finally there was a (German) article about CrypTool 2 in heise online and in Europe's largest IT magazine, the c't.
We would like to thank the many users who have sent us feedback, requests, praise and criticism. We hope you enjoy using CT2 as much as we did creating it!
We wish you a Merry Christmas and a Happy New Year 2022! Stay healthy!
Sincerely, The CrypTool 2 development team, December 2021
