Examples:

1)
var filename = process.argv[2];
var crypto = require('crypto');
var fs = require('fs');

var md5sum = crypto.createHash('md5');

var s = fs.ReadStream(filename);
s.on('data', function(d) {
md5sum.update(d);
});

s.on('end', function() {
var d = md5sum.digest('hex');
console.log(d + ' ' + filename);
});

2)
var crypto = require('crypto');
var name = 'braitsch';
var hash = crypto.createHash('md5').update(name).digest('hex');
console.log(hash); // 9b74c9897bac770ffc029102a200c5de

3)
$ npm install sha1

and then

var sha1 = require('sha1');
var hash = sha1("my message");
console.log(hash); // 104ab42f1193c336aa2cf08a2c946d5c6fd0fcdb

or

$ npm install md5

and then

var md5 = require('md5');
var hash = md5("my message");
console.log(hash); // 8ba6c19dc1def5702ff5acbf2aeea5aa

4)
const crypto = require('crypto');

const sha256 = x => crypto.createHash('sha256').update(x, 'utf8').digest('hex');

sha256('Hello, world. ');

5)
function encrypt(text,password){
var cipher = crypto.createCipher(algorithm,password)
var crypted = cipher.update(text,'utf8','hex')
crypted += cipher.final('hex');
return crypted;
}

function decrypt(text,password){
var decipher = crypto.createDecipher(algorithm,password)
var dec = decipher.update(text,'hex','utf8')
dec += decipher.final('utf8');
return dec;
}

function hashText(text){
var hash = crypto.createHash('md5').update(text).digest("hex");
//console.log(hash);
return hash;
}

function encryptThenAuthenticate(plainText,pw)
{
var encryptedText = encrypt(plainText,pw);
var hash = hashText(encryptedText);
return encryptedText+"$"+hash;
}
function VerifyThenDecrypt(encryptedAndAuthenticatedText,pw)
{
var encryptedAndHashArray = encryptedAndAuthenticatedText.split("$");
var encrypted = encryptedAndHashArray[0];
var hash = encryptedAndHashArray[1];
var hash2Compare = hashText(encrypted);
if (hash === hash2Compare)
{
return decrypt(encrypted,pw);
}
}

It can be tested with:

var doom = encryptThenAuthenticate("The encrypted text",user.cryptoPassword);
console.log(VerifyThenDecrypt(doom,user.cryptoPassword));
