# Code Repository for Temporal Converters (Java)

3+
This repository provides code used for exercises and demonstrations
4+
included in the Java version of the
5+
[Securing Application Data](https://learn.temporal.io/courses/appdatasec)
6+
training course.
7+
8+
It's important to remember that the example code used in this course was designed
9+
to support learning a specific aspect of Temporal, not to serve as a ready-to-use
10+
template for implementing a production system.
