Expand description

\brief This function retrieves the cipher-information structure associated with the given cipher ID, key size and mode.

\param cipher_id The ID of the cipher to search for. For example, #MBEDTLS_CIPHER_ID_AES. \param key_bitlen The length of the key in bits. \param mode The cipher mode. For example, #MBEDTLS_MODE_CBC.

\return The cipher information structure associated with the given \p cipher_id. \return \c NULL if the associated cipher information is not found.
