@lacspace/redact

v1.1.1Security Kit0 deps

Redact secrets & PII from logs — masks by sensitive key and by pattern (Luhn-checked cards, SSNs, JWTs, IBANs, IPs, AWS/GitHub/Slack/Stripe keys, private keys). Cycle-safe deep object redaction with partial masking, custom patterns and a never-throw guarantee. Zero-dependency, isomorphic.

Usage

redact.ts
import { redact, redactString, createRedactor } from "@lacspace/redact";

redact({
  email: "jane@example.com",
  password: "hunter2",
  headers: { authorization: "Bearer eyJhbG.eyJz.sig" },
  card: "4242 4242 4242 4242",
});
// { email: "j•••@example.com", password: "[REDACTED]",
//   headers: { authorization: "[REDACTED]" }, card: "[REDACTED]" }

redactString("token=eyJhbG.eyJz.sig for user a@b.com");
// "token=[REDACTED_JWT] for user a•••@b.com"

// bind once, use as a logger serializer
const scrub = createRedactor({ keys: ["x-internal-token"] });
logger.info(scrub(requestContext));

More in Security Kit

@lacspace/apikey

Issue & verify API keys the right way — prefixed high-entropy keys, store only the SHA-256 hash, constant-time verify, plus a storage-agnostic record toolkit: public fingerprints, hierarchical scopes, expiry, key rotation with a grace window, and revocation. Isomorphic over Web Crypto.

@lacspace/crypto

Safe, boring cryptography over Web Crypto — authenticated AES-256-GCM, PBKDF2/HKDF key derivation, SHA-256/384/512, HMAC, timing-safe compare and unbiased secure random (tokens, UUIDs, integers). Isomorphic (Node, edge, browser, RN).

@lacspace/headers

Secure HTTP headers & a typed Content-Security-Policy builder — HSTS, CSP nonces & hashes, a typed Permissions-Policy, COOP/COEP/CORP cross-origin isolation, Reporting-Endpoints and report-only, plus ready-made strict and API presets. Framework-agnostic + Next.js. Zero-dependency, isomorphic.

@lacspace/jwt

JSON Web Tokens over Web Crypto — HS/RS/ES/EdDSA signing, JWK/JWKS with kid-based key rotation, and strict expiry/issuer/audience/subject/jti checks. Plus refresh-token rotation and CSRF tokens. Isomorphic — Node, edge, browser.

@lacspace/lock

Account lockout & brute-force protection (server lock) — N-strikes with exponential or progressive/tiered backoff, per-account + per-IP composite locking, allow/deny lists, and a CAPTCHA step-up threshold before hard lockout. Pluggable store, zero-dependency, isomorphic.

@lacspace/mfa

Orchestrate multi-factor auth — combine password + TOTP + passkeys into 2FA/3FA step-up flows with NIST assurance levels (AAL), now with factor enrollment flows, failed-attempt lockout, trusted-device tokens and recovery codes. Isomorphic (bar @lacspace/otp).
