In this book, the author accounts his involvement in the DESCHALL Project, mobilizing thousands of personal computers in 1997 in order to meet the challenge to crack a single message encrypted with DES.
This was and remains one of the largest collaborations of any kind on a single project in history.
The message was unencrypted on June 18th and was found to be "Strong cryptography makes the world a safer place."
This is also the message of Matt's book. He uses a personal account and a compelling story to reveal to the uninitiated reader some insight into a topic of growing importance which is known for being quite complicated both technically and politically.
