When this book was written back in late 2003, I never would have imagined people would still be using the book as a reference over 20 years later.
As the Morgan-Kaufmann site seems to have lost the link to the original source code samples referenced in the book, I'm sharing them here.
AS-IS NO WARRANTY - this is 20+ year old source code!
The original .zip file include two libraries: bcprov-jdk14-119.jar and cryptix-jce-provider. Given how old these versions are, I'm not providing them here in binary form.
