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

• charactersToIgnore ([GooglePrivacyDlpV2CharsToIgnore]): When masking a string, items in this list will be skipped when replacing. For example, if your string is 555-555-5555 and you ask us to skip `-` and mask 5 chars with we would produce **-*55-5555. Defaults to: null.
• maskingCharacter (String.t): Character to mask the sensitive values—for example, "" for an alphabetic string such as name, or "0" for a numeric string such as ZIP code or credit card number. String must have length 1. If not supplied, we will default to "" for strings, 0 for digits. Defaults to: null.
• numberToMask (integer()): Number of characters to mask. If not set, all matching chars will be masked. Skipped characters do not count towards this tally. Defaults to: null.
• reverseOrder (boolean()): Mask characters in reverse order. For example, if `masking_character` is '0', number_to_mask is 14, and `reverse_order` is false, then 1234-5678-9012-3456 -> 00000000000000-3456 If `masking_character` is '', `number_to_mask` is 3, and `reverse_order` is true, then 12345 -> 12** Defaults to: null.
