Description

Implementation of dynamic data masking as described in CEP-20.

Dynamic data masking (DDM) allows to obscure sensitive information while still allowing access to the masked columns, and without changing the stored data. The CEP aims to provide DDM for Apache Cassandra using both native and user-defined CQL functions. These functions can be either be used on their own or be attached to specific columns in the table definition.
