Finally, here’s the program to encrypt using AES/GCM. The OpenSSL wiki example is based on it. #include #include #include #include int main (int arc, char *argv []) { OpenSSL_add_all_algorithms () ERR_load_crypto_strings () /* Set up the key and iv.
openssl$ grep -IR AES_MAXNR | grep define include/openssl/aes.h:# define AES_MAXNR 14 Lather, rinse repeat for AES_set_decrypt_key , AES_encrypt and AES_decrypt . AES_encrypt can be found at crypto/aes/aes_core.c:787 .
The available function list can be found in openssl /evp.h For my purposes I decided to use the AES API directly. I made this decision based on the fact that I seemed to get further faster with the examples that used the AES API. As I gain proficiency with OpenSSL I’ll be able to come back later and (hopefully) swallow the EVP API if I need to.

See EVP Symmetric Encryption and Decryption on the OpenSSL wiki. In fact, you should probably be using authenticated encryption because it provides both confidentiality and authenticity. See EVP Authenticated Encryption and Decryption on the OpenSSL .
