Although there is an AES specific API it's use directly is strongly discouraged becuase it makes it hard to change the algorithm in future or redirect operations to hardware. The preferred interface to all ciphers is via EVP_Cipher*() and friends. Then you can select whatever cipher you want including AES. Steve. -- Dr Stephen N. Henson.
