(warning) PLEASE NOTE: This documentation applies to Pentaho 8.1 and earlier. For Pentaho 8.2 and later, see Add a Checksum on the Pentaho Enterprise Edition documentation site.


This step calculates checksums for one or more fields in the input stream and adds this to the output as a new field.




Step name

Name of the step. Note: This name has to be unique in a single transformation.


The type of checksum that needs to be calculated.  These are the types that are available:

Result Type

Some checksum types allow to set different result types: String, Hexadecimal and Binary

Result field

The name of the result field containing the checksum

Compatibility Mode

Check this to be compatible with transformations that were created with a PDI version before 4.2.0. Before 4.2.0 there have been issues with a wrong hexadecimal encoding when Result Type is set to Hexadecimal (see details in PDI-5190).

Fields used in the checksum

The names of the fields to include in the checksum calculation.
Note: You can use the "Get Fields" button to insert all input fields from previous steps.


A simple CRC32 sample can be found in this folder of your Kettle distribution:
