Open README Back to languages

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 from the tagged Git source, load the Zig API, and run the minimal example below. It enables both masking rules explicitly and records the expected output.

Installation

zig fetch --save https://github.com/finitefield-org/mask-pii/archive/refs/tags/v0.2.0.tar.gz

Usage

src/main.zig

const std = @import("std");
const MaskPII = @import("mask-pii");

pub fn main() !void {
    var masker = MaskPII.Masker.init();
    _ = masker.maskEmails().maskPhones().withMaskChar('#');

    const allocator = std.heap.page_allocator;
    const input = "Contact: alice@example.com or 090-1234-5678.";
    const output = try masker.process(allocator, input);
    defer allocator.free(output);

    try std.io.getStdOut().writer().print("{s}\n", .{output});
    // Output: "Contact: a####@example.com or ###-####-5678."
}
