Feature available in Helium 6.0.2 release The DataSync Agent plugin architecture allows the agent to modify inbound payloads before the data is inserted into a database or saved to a file. Thus, encrypting specified values using Voltage encryption can be applied before inserting the row into your database. When you specify the list of tables and column names in the  encrypt_columns  parameter in the format of <table>:<column>;<table>:<column>;etc., i.e. incident:comments, the plugin will encrypt these specific columns that contain sensitive information for your infrastructure to decrypt and process themselves.   NOTE :  This is a custom feature for a specific use case to encrypt data saved using the Voltage API before saving it into the database.
