numberToMask property
Number of characters to mask.
If not set, all matching chars will be masked. Skipped characters do not
count towards this tally. If number_to_mask is negative, this denotes
inverse masking. Cloud DLP masks all but a number of characters. For
example, suppose you have the following values: - masking_character is
* - number_to_mask is -4 - reverse_order is false -
CharsToIgnore includes - - Input string is 1234-5678-9012-3456 The
resulting de-identified string is ****-****-****-3456. Cloud DLP masks
all but the last four characters. If reverse_order is true, all but
the first four characters are masked as 1234-****-****-****.
