Any RC4 decryption lib for ruby 1.9.2?

i found one lib which is here

https://github.com/juggler/ruby-rc4/blob/master/lib/rc4.rb

But its not working for ruby 1.9.x

it throws an error undefined method ^' for "\x1A":String__

is there any work around in ruby 1.9.x?

after googling i came to know that "In Ruby 1.9 string[index] returns character not code of the character (like it was in 1.8)." (https://rails.lighthouseapp.com/projects/8994/ticket开发者_高级运维s/3144-undefined-method-for-string-ror-234)

Thanks in advance

If that (one operation) is the only problem, couldn't you just modify the library a bit?

https://github.com/dotemacs/ruby-rc4/tree/master/lib This guy has forked it, and added some tests. The original is not maintained it looks like. This library is extremely simple and to fix that you just have to use the ord method on String.

 s = "foo"
 s[0].ord

So clone that guys git, fix it, and send him a pull request, it is the open source way :) if he does not respond then keep your fork and people will then use that.

EDIT

change line 27 to:

  0.upto(text.length-1) {|i| text[i] = [text[i].ord ^round].pack('c')}
