Jeffrey Walton fe63795638
Add byte typedef in Kalyna's anonymous namespace to avoid issues with globally scoped byte 
This check-in supports Romain Geissler's work on cleaning up our use of ::byte when it collides with std::byte. Regardless of what happens, such as removing ::byte and adding CryptoPP::byte, providing the typedef here makes Kalyna immune to the outside changes. Also see Pull Request 437 and 438.

Raw Blame History

// kalyna.cpp - written and placed in the public domain by Jeffrey Walton
// This code 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 and most utilized resource
// was Keru Kuro's public domain 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. The only downside
// was the missing big endian port.
