@types/bcrypt

What is @types/bcrypt?

@types/bcrypt provides TypeScript type definitions for the bcrypt library, which is used for hashing passwords and comparing hashed passwords. This package allows TypeScript developers to use bcrypt with type safety.

What are @types/bcrypt's main functionalities?

Hashing a password

This feature allows you to hash a plaintext password using bcrypt. The `saltRounds` parameter determines the cost factor, which influences the time needed to calculate a single bcrypt hash.

const bcrypt = require('bcrypt');
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 see if they match. It returns a boolean indicating whether the passwords match.

const bcrypt = require('bcrypt');
const myPlaintextPassword = 's0/\/\/P4$$w0rD';
const hash = '$2b$10$EixZaYVK1fsbw1ZfbX3OXePaWxn96p36Q5l8/3z6F5d7b5J8y1Z1K';
bcrypt.compare(myPlaintextPassword, hash, function(err, result) {
  if (err) throw err;
  console.log(result); // true or false
});

Generating a salt

This feature allows you to generate a salt, which can then be used to hash a password. The `saltRounds` parameter determines the complexity of the salt.

const bcrypt = require('bcrypt');
const saltRounds = 10;
bcrypt.genSalt(saltRounds, function(err, salt) {
  if (err) throw err;
  console.log(salt);
});

Other packages similar to @types/bcrypt

argon2

Argon2 is a password-hashing function that is considered to be more secure than bcrypt. It offers better resistance to GPU cracking attacks and has more configurable options. However, it may be slower and less widely supported than bcrypt.

pbkdf2

PBKDF2 (Password-Based Key Derivation Function 2) is another hashing algorithm that is widely used for password hashing. It is part of the RSA public key cryptography standards and is considered secure, but it may not be as resistant to certain types of attacks as bcrypt or Argon2.

scrypt

Scrypt is a password-based key derivation function that is designed to be more secure against hardware brute-force attacks. It is more memory-intensive than bcrypt, making it harder to implement on specialized hardware like GPUs and ASICs.
