[openssl-users] efficient way to encrypt, then sign?

Hash: SHA256

what is the lowest overhead method for encrypting using
CMS_encrypt then signing using CMS_sign? it seems like
using BIO_new_mem_buf ought to do but i don't see a method
for getting the length of the CMS_ContentInfo object to
feed to the BIO creation method.

thanks,
