GOST 28147-89 defines a special mode of using base transformation for
generating MAC. See RFC 5830 Section 8 for an English description of
this mode. Originally this mode was called "Imitovstavka", so it is
typical now to name this mode "imit".

This mode is used e.g. inside CMS files generated using GOST algorithms.
These changes were asked for by AltLinux team implementing support for
RFC 4490 in gpgsm.

With best wishes
