We created a class called SecretCode that takes a word or sentence and encodes it. It also has a method that decodes the secret message.

encryptor.rb

ENCODE = { "a" => "j", "b" => "3", "c" => "l", "d" => "m", "e" => ".",
			"f" => "o", "g" => "p", "h" => "4", "i" => "r", "j" => "&", "k" => "t",
			"l" => "u", "m" => "v", "n" => "#", "o" => "x", "p" => "y", "q" => "9",
			"r" => "a", "s" => "$", "t" => "c", "u" => "[", "v" => "e", "w" => "f",
			"x" => "g", "y" => "8", "z" => "i", " " => " " }

DECODE = { "j" => "a", "3" => "b", "l" => "c", "m" => "d", "." => "e",
			"o" => "f", "p" => "g", "4" => "h", "r" => "i", "&" => "j", "t" => "k",
			"u" => "l", "v" => "m", "#" => "n", "x" => "o", "y" => "p", "9" => "q",
			"r" => "a", "s" => "$", "t" => "c", "u" => "[", "v" => "e", "w" => "f",
			"x" => "g", "y" => "8", "z" => "i" }

class SecretCode
	def initialize(word)
		@word = word
		@encoded_word = []
		@decoded_word = []
	end

	def split_word
		@word.split("")
	end

	def encode 
		split_word.each do |letter|
			@encoded_word << ENCODE[letter.downcase]
		end
		p @encoded_word.join
	end

	def decode
		split_word.each do |letter|
			@decoded_word << DECODE[letter.downcase]
		end
		p @decoded_word.join
	end

code = SecretCode.new("Hello world")
code.encode


code = SecretCode.new("4.a. r$ j $.#c.#l.")
code.decode
