Hello Openssl team, GOST89 cipher algorithm seems to be the only cipher algorithm supporting more than one sets of S-boxes.
Current implementation of the GOST89 cipher provided by the ccgost engine does not allow to specify usage of particular S-boxes for a particular EVP_CIPHER_CTX instance. If I understand correctly, the only way to do it is to specify a ctrl-command and implement it in the engine. Is it OK to reuse EVP_CTRL_INIT ctrl command for this purpose or it will be better to add a special value for this? Thank you! -- SY, Dmitry Belyavsky
