(В копилку ошибочных реализаций.)

В одном российском линуксе, хэш для данных с длинной кратной 64
считаются иначе чем у всех остальных:

  $ perl -E 'print "\x00" x 0'  | gostsum --gost-2012
  106c0c2070522f9ed0753e143809578a3b27711c5bc99553c3eaca250de2a30a  -
  $ perl -E 'print "\x00" x 1'  | gostsum --gost-2012

  $ perl -E 'print "\x00" x 64' | gostsum --gost-2012

Интересно что там могло пойти не так.
