Practical Cryptography in Java

Practical Cryptography in Java covers everything you need to know in order to build cryptographically secure systems.

Free code examples included inside for download.

Who should read this book?
We have designed this book for people who already have some experience with Java, we move through the syntactical aspects quite quickly so we can focus on the actual implementation of cryptography. As for previous knowledge of cryptography; you won't need much as we cover all of the concepts throughout the book. We highlight key points and definitions as we go through so there is absolutely no confusion.

Fear not, the cryptographic framework is actually quite reasonable once you learn the basics.

What will i know by the end?
Good question! - We cover a lot in this book, everything from encryption / decryption to message digests and certificate signing, the Java cryptographic framework is quite extensive and we cover it all.

Topics covered include:
Text encryption and decryption


File encryption and decryption


How to use cryptographically secure random bit and digit selectors


Calculating the checksum of files and messages


Creating hashes (message digests)


Strengthening hashes with salts and passwords (HMAC)


Performing asymmetric and symmetric cryptography


Using public key cryptography to sign digitally messages


Understanding digital signatures


Password generation


The important cryptographic protocols
