    @item 34.11-94's digest is reversed. Now it is compatible with TC26's
      HMAC and PBKDF2 test vectors
    @item @code{gogost-streebog} is split to @code{streebog256} and
        @code{streebog512} correspondingly by analogy with sha* utilities
    @item added VKO 34.10-2012 support with corresponding test vectors
    @item @code{gost3410.DigestSizeX} is renamed to
        @code{gost3410.ModeX} because it is not related to digest size,
