Subject: Re: working with large binary strings?

Hi, so in the spirit of not cluttering the forum I will ask my somewhat 
unrelated but still related question here. So I have finished 
implementing this, but have run into one issue, when I XOR strings 
together like this:

  def xor_strings(string_array)

    processed_strings = []

    string_array.each do |string|
      processed_strings << NArray.to_na(string, "byte")
    end

    processed_strings.inject(:^).to_s
  end

the result is not always the same size as the set of strings. I believe 
some optimization is being done for me and I need to avoid it, however 
googling for Narray and XOR has not led me to any success. I swear this 
is my last question regarding this, as after I have this fixed I am all 
the way done :D
