Crate tc_gost28147 

GOST 28147-89 single-block cipher with caller-selected S-boxes.

Keys are 32 bytes and blocks are 8 bytes. The S-box is a parameter; choosing a different table changes the cipher. Standard tables live in s_box. Gost28147ParamsRef defaults to s_box::DEFAULT; custom parameter types implement Gost28147Params.

The alloc feature adds Gost28147ParamsOwned, which owns its key and S-box and wipes them on drop.
