Class CharacterMaskConfig (3.7.1)

CharacterMaskConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Partially mask a string by replacing a given number of characters with a fixed character. Masking can start from the beginning or end of the string. This can be used on data of any type (numbers, longs, and so on) and when de-identifying structured data we'll attempt to preserve the original data's type. (This allows you to take a long like 123 and modify it to a string like **3.

Attributes

NameDescription
masking_character str
Character to use to mask the sensitive values—for example, ``*`` for an alphabetic string such as a name, or ``0`` for a numeric string such as ZIP code or credit card number. This string must have a length of 1. If not supplied, this value defaults to ``*`` for strings, and ``0`` for digits.
number_to_mask int
Number of characters to mask. If not set, all matching chars will be masked. Skipped characters do not count towards this tally.
reverse_order bool
Mask characters in reverse order. For example, if ``masking_character`` is ``0``, ``number_to_mask`` is ``14``, and ``reverse_order`` is ``false``, then the input string ``1234-5678-9012-3456`` is masked as ``00000000000000-3456``. If ``masking_character`` is ``*``, ``number_to_mask`` is ``3``, and ``reverse_order`` is ``true``, then the string ``12345`` is masked as ``12***``.
characters_to_ignore Sequence[google.cloud.dlp_v2.types.CharsToIgnore]
When masking a string, items in this list will be skipped when replacing characters. For example, if the input string is ``555-555-5555`` and you instruct Cloud DLP to skip ``-`` and mask 5 characters with ``*``, Cloud DLP returns ``***-**5-5555``.
