simple-file-verification

Library to calculate SFV checksums from files and streams.

Installation

npm install simple-file-verification -S

Usage

import * as SFV from "simple-file-verification";
import { createReadStream } from "node:fs";

(async () => {
	await SFV.fromFile("path/to/file");
	await SFV.fromFiles("path/to/*.pdf");
	await SFV.fromStream(createReadStream("path/to/file"));
})();

API

All API methods default to SFV's standard CRC32 algorithm. You can also specify the extended SFV (.sfvx) algorithms MD5, SHA-1, SHA-256, or SHA-512.
