This 90-page chapter covers the basic theory behind lattices in a lightweight fashion. The theory is accompanied with lots of practical examples, SageMath code, and cryptographic challenges. The input data of the challenges is bundled in text files in chal_i_helper.zip.
In this free, 500+ pages book delivered with the CrypTool applications you will find predominantly mathematically oriented information on learning, using and experimenting cryptographic procedures. The 12th edition is a major update of the book.
The main chapters have been written by various authors and are independent from each another.

On around 50 slides, this CrypTool presentation gives an overview of the whole CrypTool project including its 5 subprojects.
This presentation, with over 100 slides, gives an exhaustive overview about the features of CrypTool 1.4, and a short overview of the CrypTool project. colorful innovative presentation, held in Spain, November 2008 by Gonzalo Álvarez Marañón, describes the past, present and future of CrypTool in a visual appealing way.
This presentation shows the basics of the RSA cipher in an attractive interactive way.
