How to protect sensitive data in a Temporal Application

What this post added

This post elaborates on data security within Temporal applications by focusing on application-level encryption using Payload Codecs. It details the components of the Data Converter (Payload Converter, Failure Converter, Payload Codec) and explains how Payload Codecs can be implemented to encrypt and decrypt sensitive data before it is transmitted to or received from the Temporal Service. This enhances security by ensuring the Temporal Service never has access to unencrypted sensitive data.
