sha1 hash node.js

sha1-hash-node.js

const crypto = require('crypto')

const sha1 = path => new Promise((resolve, reject) => {
	const hash = crypto.createHash('sha1')
	const rs = fs.createReadStream(path)
	rs.on('error', reject)
	rs.on('data', chunk => hash.update(chunk))
	rs.on('end', () => resolve(hash.digest('hex')))
})

sha1('./test.txt').then(hash => {
  console.log(hash)
}).catch(err => {
  throw new Error(err)
})

@benjaminhoffman is right. 👍

async function hashOfStream(readable) {
    return await once(
        readable.pipe(crypto.createHash('sha1').setEncoding('hex')),
        'finish')
}

thanks bro

Thank you!
