Hash

With the Hash function you can mask data in selected fields, making it unreadable. You do this by hashing the data using a standard algorithm, based on your preferences. This is a one-way transformation and the original payload cannot be recovered when hashed.

Supported value types are:

string
number
boolean
date

This functionality can be used to supply data output that has to be processed outside of the stream without providing certain types of sensitive data in clear text. Such provisions are used in situations where data protection regulations apply.

Configuration

The Hash function is enabled when you select the fields to be mapped in the Fields drop-down list. Multiple fields can be selected at once. You can also enter the fields manually one by one in the Add field box and then click the + button.

The following algorithm hashing methods are supported:

SHA-256 (default)
SHA-1
MD5 (considered insecure)

During configuration, the Preview option enables you to view the hashed output of the selected fields.
