Question

I am using this line to generate a sha1 id for node.js:

crypto.createHash(\'sha1\').digest(\'hex\');

The problem is that it\'s returning th

Answer 1

Using crypto is a good approach cause it's native and stable module, but there are cases where you can use bcrypt if you want to create a really strong and secure hash. I use it for passwords it has a lot of techniques for hashing, creating salt and comparing passwords.

Technique 1 (generate a salt and hash on separate function calls)

const salt = bcrypt.genSaltSync(saltRounds);
const hash = bcrypt.hashSync(myPlaintextPassword, salt);

Technique 2 (auto-gen a salt and hash):

const hash = bcrypt.hashSync(myPlaintextPassword, saltRounds);
