Email masking

Masks local parts while preserving domain visibility.

Phone masking

Masks sensitive digits while keeping format and suffix visibility.

Builder-style API

Enable email/phone masking and mask character explicitly before processing.

Install and start

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

Installation

.package(url: "https://github.com/finitefield-org/mask-pii", exact: "0.2.0")

Usage

main.swift

import MaskPII

let masker = Masker()
    .maskEmails()
    .maskPhones()
    .withMaskChar("#")

let input = "Contact: alice@example.com or 090-1234-5678."
let output = masker.process(input)

print(output)
// Output: "Contact: a####@example.com or ###-####-5678."
