Developing Custom JSON Converters for Data Masking in C#

In a recent development, a method has been shared on how to use custom JsonConverters to export data that masks sensitive information such as social security numbers and credit card numbers. This technique is particularly useful when dealing with cases where certain data must be hidden from unauthorized access.

The approach involves creating custom JsonConverter classes for both social security numbers and credit cards. The read method returns the original value, while the write operation uses masking extensions to hide sensitive information.

This development provides a valuable tool for developers looking to protect sensitive data in their applications. By separating the converter code from the frontend, it can be easily reused across different projects.
