Cryptography Essentials in Java

Explore the Java SE options to encrypt and decrypt data

Description

In this course you will explore the Java SE options to encrypt and decrypt data. After a short historic overview of Cryptography, you will learn the difference between symmetric and asymmetric encryption and you will understand the details of AES. Next the JavaSE classes that are used to perform symmetric encryption are covered and used in the lab. Then you will learn the concepts behind asymmetric encryption and the details of RSA. Also the JavaSE classes that are needed to do asymmetric encryption are examined and used in the lab. Then you will learn what hashing is and how you can digitally sign documents. You'll also experience the use of certificates and how to use them in Java.
