What is @types/bcryptjs?
@types/bcryptjs provides TypeScript type definitions for the bcryptjs library, which is used for hashing passwords and comparing hashed passwords.
What are @types/bcryptjs's main functionalities?
Hashing a Password
This feature allows you to hash a plaintext password using bcryptjs. The `hash` function takes a plaintext password and a salt round value, and returns a hashed password.
const bcrypt = require('bcryptjs');
const saltRounds = 10;
const myPlaintextPassword = 's0/\P4$$w0rD';
bcrypt.hash(myPlaintextPassword, saltRounds, function(err, hash) {
if (err) throw err;
console.log(hash);
});
Comparing a Password
This feature allows you to compare a plaintext password with a hashed password to check if they match. The `compare` function returns a boolean indicating whether the passwords match.
const bcrypt = require('bcryptjs');
const myPlaintextPassword = 's0/\P4$$w0rD';
const hash = '$2a$10$EixZaYVK1fsbw1ZfbX3OXePaWxn96p36z4u/2eWvJ1p6d7y6J0bWm';
bcrypt.compare(myPlaintextPassword, hash, function(err, res) {
if (err) throw err;
console.log(res); // true or false
});
Generating a Salt
This feature allows you to generate a salt, which can be used for hashing passwords. The `genSalt` function takes a salt round value and returns a generated salt.
const bcrypt = require('bcryptjs');
const saltRounds = 10;
bcrypt.genSalt(saltRounds, function(err, salt) {
if (err) throw err;
console.log(salt);
});
Other packages similar to @types/bcryptjs
bcrypt
bcrypt is a library for hashing passwords using the bcrypt algorithm. It is similar to bcryptjs but is a native implementation, which can offer better performance. However, it requires native bindings and may be more difficult to install on some systems.
argon2
argon2 is a library for hashing passwords using the Argon2 algorithm, which is considered to be more secure than bcrypt. It provides similar functionalities for hashing and verifying passwords but uses a different algorithm.
pbkdf2
pbkdf2 is a library for hashing passwords using the PBKDF2 algorithm. It is part of the Node.js crypto module and provides functionalities for hashing and verifying passwords, similar to bcryptjs but using a different algorithm.
