@dork7/filehasher

Password-protected file encryption (AES-256-GCM) with a CLI and library API. For one-way file fingerprints (e.g. SHA-256), use the hash command.

Install

npm install @dork7/filehasher

CLI

npx filehasher encrypt -i plain.txt -o secret.fhc
npx filehasher decrypt -i secret.fhc -o plain.txt

Omit -p / --password for a masked prompt (encrypt asks for confirmation). Passwords are not saved to disk.

.env helpers (same directory as the working directory):

npx filehasher env lock    # .env → .env.fhc (alias: env hash)
npx filehasher env unlock  # .env.fhc → .env (alias: env dehash)

One-way digest (not encryption):

npx filehasher hash ./file.txt

Library

import { encrypt, decrypt, hashBuffer } from "@dork7/filehasher";

Requirements

Node.js 18+.
