Reference documentation and code samples for the Data Loss Prevention V2 Client class CharacterMaskConfig.
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.

Optional. Data for populating the Message object. |
↳ masking_character |
string
Character to use to mask the sensitive values—for example, |
↳ 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. If |

bool
Mask characters in reverse order. For example, if |

array<Google\Cloud\Dlp\V2\CharsToIgnore>
When masking a string, items in this list will be skipped when replacing characters. For example, if the input string is |
getMaskingCharacter
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.

getNumberToMask
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
isfalse
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. Ifreverse_order
istrue
, all but the first four characters are masked as1234-****-****-****
.

getReverseOrder
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***
.

setReverseOrder
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***

and you
instruct Cloud DLP to skip -
and mask 5 characters with *
, Cloud DLP
returns ***-**5-5555
.
