Email masking

Masks the local part while keeping the domain visible.

Phone masking

Masks sensitive digits while preserving the format and visible suffix.

Builder-style API

Enable email and phone rules, and set the mask character explicitly before processing.

Install and run a first example

Use the tagged source checkout while the Racket Package Catalog package is planned, load the Racket API, and run the minimal example below. It enables both masking rules explicitly and records the expected output.

Installation

git clone --branch v0.2.0 --depth 1 https://github.com/finitefield-org/mask-pii.git

Usage

example.rkt

#lang racket

(require mask-pii)

(define masker
  (with-mask-char #\#
    (mask-phones
      (mask-emails (make-masker)))))

(displayln
  (process masker "Contact: alice@example.com or 090-1234-5678."))
;; Expected output: "Contact: a####@example.com or ###-####-5678."
