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 Nim package list / Nimble package is planned, load the Nim 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.nim

import mask_pii

let masker =
  newMasker()
    .maskEmails()
    .maskPhones()
    .withMaskChar('#')

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

assert outputText == "Contact: a####@example.com or ###-####-5678."
