+/// \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.
