How to encrypt, decrypt data using DUKPT and 3DES algorithm in iphone for a card reader application?

Question

I have reffered this code and successfuly created IPEK and PEK for differant TKSN and Now how do I encrypt this keys to my card reader device and how do decrypt the card information using those keys. In fact I'm not familiar with the DUKPT techniques and I was so new to that.Any suggestions will be appreciated

Note : I have BDK and Final TKSN values how do I encrypt and decrypt these values in my device ?

@Ruban Did you figure out how to get the BDK from the two "Key Component" values? — mdimarca, Jul 28 '18 at 19:50
@mdimarcaThe Card Reader Provider(Magtek) asked me to pay for each decryption. So we did not use this provider. — Ruban, Jul 30 '18 at 01:39

Searching on the same thing and I found this example library on github: https://github.com/mburshteyn1/DUKPT

I haven't tried it myself yet but it takes BDK and KSN as input which you have.

This isn't really an answer, but could be a comment. – zck Feb 13 '14 at 22:34
Did you end up getting that library to work? I've been trying it to no avail so far – mdimarca Jul 28 '18 at 19:51
