BCrypt in Ruby
I stumbled across this post from Kieran, that explains bang on how BCrypt works.
# Create hash of password pass = BCrypt::Password.create('TestPassword') => "$2a$10$3.D6D2htbiRrezmZUhePV.gaQlc3ZjFYD9hv43khN5eWP5y8BGUXG" # Pass the hash you have stored to Password.new db_hash = BCrypt::Password.new("$2a$10$3.D6D2htbiRrezmZUhePV.gaQlc3ZjFYD9hv43khN5eWP5y8BGUXG") # Compare the input from the user to the password stored db_hash == "TestPassword" => true db_hash == "NotRealPassword" => false
Additionally check out the gem’s excellent docs on github.
