The default masking method is effective when the final representation of the masked data is not a concern. The client honors default masks for all data types. You can set up the default mask using the prefix D: and the masking occurs as follows:
Data type Default mask
Int, Int64, Decimal 0 (zero)
Date, Datetime, Datetime-tz 01/01/1900 00:00:00.00:00
Character
  • For strings that are up to four characters long, each character is masked with an X. For example, data is displayed as XXX.
  • Strings longer than four characters are masked as

    XXXX.

    Note: If the user does not have permission to view the unmasked value, a mask of a single character (X) is applied to a field with an unknown value or an empty string
