mask-pii for Haskell

Choose the Haskell implementation of mask-pii to mask email and phone PII in logs and data pipelines. The workflow remains easy to review.

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 Hackage package is planned, load the Haskell 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.hs

import MaskPII (Masker, newMasker, maskEmails, maskPhones, withMaskChar, process)

main :: IO ()
main = do
  let masker = withMaskChar '#'
             $ maskPhones
             $ maskEmails newMasker
  putStrLn $ process masker "Contact: alice@example.com or 090-1234-5678."
  -- => "Contact: a####@example.com or ###-####-5678."
