Module: Olyx::Guardrails::Pii::SinValidator

Defined in:
lib/olyx/guardrails/pii/sin_validator.rb

Overview

Validates Canadian Social Insurance Numbers with the same Luhn checksum as card numbers, but at SIN's fixed 9-digit length — LuhnValidator enforces its own 13-digit floor for card use, so this applies SIN's length rule against LuhnChecksum directly.
