Subject: hexlify and unhexlify

Is there any built-in module that does this for me?

    def hexlify(msg)
        msg.split("").collect { |c| c[0].to_s(16) }.join
    end
    def unhexlify(msg)
        msg.scan(/../).collect { |c| c.to_i(16).chr }.join
    end

    puts hexlify("In Ruby...")
    puts unhexlify("496e20527562792e2e2e")
