How to use OpenSSL's SHA256 functions

Question

I\'m writing a program to get myself acquainted with OpenSSL, libncurses, and UDP networking. I decided to work with OpenSSL\'s SHA256 to become familiar with industry encry

Answer 1

This works fine on my system, but you might try:

extern "C" {
#include 
}

which tells g++ that all the stuff in openssl/sha.h is declared as "C" functions.

BTW, how old is your OpenSSL?
