This section describes changes to the Data Masking transformation that you create in the PowerCenter Client.
Key Masking Technique
Effective in version 9.6.1, the key masking algorithm is changed. A mapping created in an earlier version that uses the key masking technique might create different masked output after upgrade to 9.6.1.
Previously, a mapping that used the key masking technique would create the same masked output when run after upgrade.
