This FREE STUDENT VERSION of the book contains many widgets (21) including an interactive modular calculator for RSA and interactive messages cypher / decypher (RSA 128 - 2048 bits).
In this free student version, exercices have some guidance and answers (Ch.6), but no detailed solutions (+9 Widgets Keynote see Full Version).
This book is not aimed only at students or high school teachers, but also to anyone interested in discovering the fascination of primes and understand RSA cryptography. Bases in algebra are welcome but not required.
