5 /// \brief Classes for the Kalyna block cipher
6 /// \details The Crypto++ implementation relied upon three sources. First was Oliynykov, Gorbenko, Kazymyrov,
7 /// Ruzhentsev, Kuznetsov, Gorbenko, Dyrda, Dolgov, Pushkaryov, Mordvinov and Kaidalov's "A New Encryption
8 /// Standard of Ukraine: The Kalyna Block Cipher" (http://eprint.iacr.org/2015/650.pdf). Second was Roman
9 /// Oliynykov and Oleksandr Kazymyrov's GitHub with the reference implementation
10 /// (http://github.com/Roman-Oliynykov/Kalyna-reference). The third resource was Keru Kuro's implementation
11 /// of Kalyna in CppCrypto (http://sourceforge.net/projects/cppcrypto/). Kuro has an outstanding
12 /// implementation that performed better than the reference implementation and our initial attempts.
