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

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.

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 ?

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"
