Bcrpyt	The bcrypt hashing function allows us to build a password security platform.	2021-10-15	2021-10-15

Bcrypt is among the most popular and safest, one-way hashing functions for passwords.

Installation

npm install bcryptjs

Usage - Sync

To hash a password:

var bcrypt = require('bcryptjs');
var salt = bcrypt.genSaltSync(10);
var hash = bcrypt.hashSync("B4c0/\/", salt);
// Store hash in your password DB.

To check a password:

// Load hash from your password DB.
bcrypt.compareSync("B4c0/\/", hash); // true
bcrypt.compareSync("not_bacon", hash); // false

Auto-gen a salt and hash:

var hash = bcrypt.hashSync('bacon', 8);

Usage - Async

To hash a password:

var bcrypt = require('bcryptjs');
bcrypt.genSalt(10, function(err, salt) {
    bcrypt.hash("B4c0/\/", salt, function(err, hash) {
        // Store hash in your password DB.
    });
});

To check a password:

// Load hash from your password DB.
bcrypt.compare("B4c0/\/", hash, function(err, res) {
    // res === true
});
bcrypt.compare("not_bacon", hash, function(err, res) {
    // res === false
});
// As of bcryptjs 2.4.0, compare returns a promise if callback is omitted:
bcrypt.compare("B4c0/\/", hash).then((res) => {
    // res === true
});

Auto-gen a salt and hash:

bcrypt.hash('bacon', 8, function(err, hash) {
});
