    The Substring masking format extracts a portion of the original column
    value and uses it to replace the original value. It internally uses the
    Oracle SUBSTR function. It takes the start position and length as input,
    extracts substring from the original value using SUBSTR, and uses the
    substring to replace the original value. To learn more, check Substring
    in the Data Safe documentation.
