When not the default 12 bytes (96 bits) sets the IV length using EVP_CIPHER_CTX_ctrl with type EVP_CTRL_GCM_SET_IVLEN An adverb which means "doing without understanding". An initialization vector (IV) or starting variable (SV) is a block of bits that is used by several modes to randomize the encryption and hence to produce distinct ciphertexts even if the same plaintext is encrypted multiple times, without the need for a slower re-keying process. Both randomness and nonrepetitiveness are crucial to prevent attackers from finding patterns in similar parts of the encrypted message and then using this information to decrypt the message. Application must allocate space for the output buffer.
