gnutls_cipher_get_iv_size - Man Page
unsigned gnutls_cipher_get_iv_size(gnutls_cipher_algorithm_t algorithm);
- gnutls_cipher_algorithm_t algorithm
is an encryption algorithm
This function returns the size of the initialization vector (IV) for the provided algorithm. For algorithms with variable size IV (e.g., AES-CCM), the returned size will be the one used by TLS.
