What is Ruby Bcrypt and how do I use it?

Ruby Bcrypt is a gem that provides a way to hash passwords securely using the Bcrypt algorithm. It's widely used for storing passwords safely.

How do I install the Ruby Bcrypt gem?

You can install it by adding gem 'bcrypt' to your Gemfile and running bundle install, or by running gem install bcrypt in your terminal.

Can you show me an example of how to hash a password?

Sure! Here's a simple example:

require 'bcrypt'

password = 'my_secret_password'
hashed_password = BCrypt::Password.create(password)
puts hashed_password

How do I verify a password against the hashed version?

You can verify a password like this:

if BCrypt::Password.new(hashed_password) == password
  puts 'Password is valid!'
else
  puts 'Invalid password!'
end
