I thought I may be able to calculate the minimal size but realized that it requires including header files for SHA256 and MD5.

It would probably be good to have some test or debug logic that does calculate the minimum size.

AC_CHECK_SIZEOF? Then maybe we can do std::max. Try it if you are interested.

This partially reverts #8719. I think the memory leak is because of not calling the destructor of
CryptoContextBase. Although use ofnewanddeletemakes the code easy to understand, we should avoid the memory allocation.
