You can use the format preserving encryption technique to encrypt or decrypt source data. You can configure the technique to preserve format and metadata, preserve metadata, or change the metadata.
You can sort the order of entries in a relational dictionary that you use for Substitution masking. Sort the order of entries in the dictionary based on the serial number column to ensure that the order remains consistent and generates consistent masked data.
Optimize dictionary usage
Optimize dictionary usage to increase the number of masked values used from the dictionary in a Substitution masking technique that you configure for repeatable output.
