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

Install the verified Go Module Proxy / pkg.go.dev release, load the Go API, and run the minimal example below. It enables both masking rules explicitly and records the expected output.

Usage

main.go

package main

import (
	"fmt"

	"github.com/finitefield-org/mask-pii/go"
)

func main() {
	masker := maskpii.New()
		.MaskEmails()
		.MaskPhones()
		.WithMaskChar('#')

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

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