Features:
- Uses GOST 28147-89 block cipher inside.
- You have to specify S-box to use for that block cipher.
- Standard does not define how digest output must be presented –
that is why there are incompatible implementations, that output digest
as either little-endian or big-endian value.
Implementations: here.
