What are some examples of using bcrypt for password hashing?

Bcrypt is commonly used for hashing passwords securely. For example, in a Node.js application, you can use the bcrypt library to hash a password like this:

const bcrypt = require('bcrypt');
const saltRounds = 10;
const myPlaintextPassword = 's0/\/\/P4$$w0rD';

bcrypt.hash(myPlaintextPassword, saltRounds, function(err, hash) {
  // Store hash in your password DB.
});

How do I compare a hashed password with a plain text password?

You can use the bcrypt.compare method to compare a plain text password with a hashed password. Here's an example:

bcrypt.compare(myPlaintextPassword, hash, function(err, result) {
  // result == true if the passwords match
});

Is bcrypt the best option for password hashing?

Bcrypt is a popular choice due to its adaptive nature, which makes it resistant to brute-force attacks. However, other algorithms like Argon2 are also considered secure.

Can I use bcrypt in Python?

Yes, you can use bcrypt in Python with the bcrypt library. Here's a simple example:

import bcrypt

password = b'supersecret'
hash = bcrypt.hashpw(password, bcrypt.gensalt())
