I am also thinking about to port openssl to an embedded system and noticed the
the discussion.
What sizes have you come down to ? and does your embeded system have filestorage ?
fopen() or is the certificates
stored in char []?
The core question is what i takes to port it to an embeded system.
Best Regards
Andreas Bäck
