hash

Hash selected columns in a data extract.

Introduction

Use the hash enrichment to hash selected columns in a data extract. The hashed data is added to a new column in the data extract.

The three available hashing methods are:

sha224

Hashes data using a 112-bit signature.

sha256

Hashes data using a 256-bit signature.

md5

Hashes data using a 128-bit signature.

Creating the enrichment

For more information on creating an enrichment, see Using custom scripts.

Configuring the enrichment

To configure the enrichment, fill in the following fields. Required fields are marked with an asterisk (*).

Target Field Name

Specify the name of the new field to add to the data extract.

Source Fields

Enter the names of the columns to hash. Click to add a new column to hash.

Algorithm

Select the hashing method with which to hash the data in the selected columns.

Subtable

Enter the name for a subtable that you want to contain the enriched data. The enrichment is applied to the whole data extract, then the enriched data is output into the subtable you have named here.

This subtable is a temporary table, which means it only exists for this custom script. You can apply additional instructions within the same custom script to the subtable. However, the subtable cannot be used in any other custom scripts.
