Encrypt the data in "plaintext" using the ciphername, key, and initial vector, returning the encrypted data in "encrypted" and a tag value in "tag" to be used to ensure that the ciphertext and AAD are not tampered with in transit.
Syntax 
crypto_evp_encrypt_auth( ciphername, key, iv, aad, plaintext, encrypted var, tag var )
