I've never programmed in ruby and I'm porting this to c# for the .net crowd.

I get an issue where left_key_half is always 0 after being shifted >> 64

I'm calling key_gen (line 32 encryption.rb),then (line 41 encryption.rb) encrypt_register, goes to (line 84 encryption.rb) left_key_half

left_key_half is always 0 after the shift.

This is happening on my side because the left_key_half is 64bits long and the whole thing is being shifted out to 0

Is the indented code line 85-90 in encryption.rb doing something that I don't quite understand because I don't know ruby or is it just a formatting issue?

What I need to know is, Is the Ruby code doing something special based on the indented syntax?

I have the ansi doc for DUKPT and will read up on it, but your help would be greatly appreciated.

I noticed in commit b15331f you were working on implementing the encryption class. I'm a bit new to ruby but I was able to get it to work after minor adjustments to your code. Was this feature ever planned to be completed? I wouldn't mind sharing my code if it was something that you weren't able to complete.

Gem spec is titled "duptk" instead of "dukpt"

It would be useful if this library could generate future keys (see http://www.andyorrock.com/2006/11/creating_an_ipe.html)

Hello @ryanbalsdon

I noticed this commit fixes the deprecation warning for OpenSSL::Cipher::Cipher https://github.com/Shopify/dukpt/blob/master/lib/dukpt/encryption.rb#L142

Is there anything I can help with to push a new release to rubygems.org ?
