Hello, I have been porting reference implementation to pure java. https://github.com/octabase/fnr-java

I understand that you use the even bits as one half and the odd bits as other half in the implementation. I wonder that the ciphertext has the same even/odd bits format?

For example, if you follow the encryption scheme (divide the original text into two separate halves), the ciphertext is 10101010. However, if you use the above trick (even/odd bits format) the ciphertext will be 11110000.

Thanks.

When building libfnr on OS X / Yosemitie with XCode 6.2 this morning, I notice a ton of deprecated warnings about SSL functions. I'm guessing you've specifically chosen to use those functions -- but perhaps there are updated versions of those functions available? (we may have even discussed this at one point...? I don't remember)

See https://gist.github.com/jsquyres/cb8bfff9c5ca19e925dc for the full output of the build.

But there's a few warnings that are a little more concerning:

• https://gist.github.com/jsquyres/cb8bfff9c5ca19e925dc#file-libfnr-warnings-L121 implicit declaration of RAND_bytes
• https://gist.github.com/jsquyres/cb8bfff9c5ca19e925dc#file-libfnr-warnings-L132 implicit sign conversion
• https://gist.github.com/jsquyres/cb8bfff9c5ca19e925dc#file-libfnr-warnings-L139 implicit sign conversion
• https://gist.github.com/jsquyres/cb8bfff9c5ca19e925dc#file-libfnr-warnings-L146 implicit sign conversion
• https://gist.github.com/jsquyres/cb8bfff9c5ca19e925dc#file-libfnr-warnings-L156 implicit declaration of RAND_bytes
• https://gist.github.com/jsquyres/cb8bfff9c5ca19e925dc#file-libfnr-warnings-L167 implicit sign conversion
• https://gist.github.com/jsquyres/cb8bfff9c5ca19e925dc#file-libfnr-warnings-L174 implicit sign conversion

Someone may want to have a look. :-)

Hi, do you have an example for credit card ranking?

If I understand correctly, FNR is a format-preserving encryption algorithm. What advantages might it provide compared to other format-preserving encryption algorithms, such as AES-FFX? It would be good to summarise this in the README.
