Data types

Every kind of personal or sensitive data the built-in recognizers detect

Forty-six built-in regex recognisers ship by default, grouped into seven categories. Each recogniser is identified by an entity type that drives the replace operator's placeholder and is tagged with a category for opt-in subsetting via DBMCP_PII_CATEGORIES / pii.categories. Several recognisers ship with a checksum or context validator (Luhn, mod-11, ABA, EIN prefix, JWT header, PEM type-match, IRS ITIN range, NPI Luhn, DEA check digit, ICAO 9303 check digit, ISO 7064, KVNR / LANR / RVNR checksums, keyword context) that promotes the match to maximum confidence and rejects look-alikes.
