Encryption in Java with JCA and Bouncy Castle API.

In this post, I cover the basics, what I have learned about encryption while building a module to protect Personal Identifiable Information (PII) data using the Java Cryptography API (JCA) and Bouncy Castle API.

You may find this post helpful if:

• You are new to encryption or not sure how to use the JCA/Bouncy Castle to do encryption in Java.
• You face some issues with key length using the JCA.
• You are not sure which types of encoding to use for encryption.
