How does it work?

Bcrypt made it super simple to encrypt and check passwords, with a couple of functions, you can generate a hashed password for your users and allow them to log in to your website!

Keep in mind that once the password is encrypted, you cannot decrypt it.

Encrypt a password

To encrypt a password, you are first going to have to generate a salt for the password. Once the salt is generated, you can use it to hash your password.

const passwordSalt = bcrypt.genSaltSync(10);
const hashedPassword = bcrypt.hashSync(password, passwordSalt);
