// kalyna.h - written and placed in the public domain by Jeffrey Walton
// Based on public domain code by Keru Kuro.
/// \file kalyna.h
/// \brief Classes for the Kalyna block cipher
/// \details The Crypto++ implementation relied upon three sources. First was Oliynykov, Gorbenko, Kazymyrov,
/// Ruzhentsev, Kuznetsov, Gorbenko, Dyrda, Dolgov, Pushkaryov, Mordvinov and Kaidalov's "A New Encryption
/// Standard of Ukraine: The Kalyna Block Cipher" (http://eprint.iacr.org/2015/650.pdf). Second was Roman
/// Oliynykov and Oleksandr Kazymyrov's GitHub with the reference implementation
/// (http://github.com/Roman-Oliynykov/Kalyna-reference). The third resource was Keru Kuro's implementation
/// of Kalyna in CppCrypto (http://sourceforge.net/projects/cppcrypto/). Kuro has an outstanding
/// implementation that performed better than the reference implementation and our initial attempts.
