Calculates a SHA-256 of a given file

Install

Using yarn:

yarn add file-to-sha256

or using npm:

npm install file-to-sha256

Usage in the browser

import { blobToSHA256 } from 'file-to-sha256'

const hash = await blobToSHA256(fileInput.files[0])

Usage in node

For file paths

const { pathToSHA256 } = require('file-to-sha256')

const hash = await pathToSHA256('/path/to/file')

For buffers or strings

const fs = require('fs')
const { dataToSHA256 } = require('file-to-sha256')

const buffer = fs.readFileSync('/path/to/file')

const hash = dataToSHA256(buffer)
