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 Hare Project Library package is planned, load the Hare 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

main.ha

use fmt;
use maskpii;

export fn main() void = {
	let m = maskpii::new();
	maskpii::mask_emails(&m);
	maskpii::mask_phones(&m);
	maskpii::with_mask_char(&m, '#');

	let input = "Contact: alice@example.com or 090-1234-5678.";
	let output = maskpii::process(&m, input)!;
	defer free(output);

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