I wanted to check if there is a way to use cryptographic cipher suites without including following config options.
In most user space application clients like those of mqtt, co-ap https etc, I have observed we associate a tls_config with a socket as a socket_opt. I wanted to know if we could use a very small set of cipher suites just by providing the list of cipher suites in tls_config->cipher_list and skip enabling the CONFIG_MBEDTLS, CONFIG_MBEDTLS_BUILTIN. I don’t want to use config-tls-generic config file as the default as it contains almost all the cipher suites
At Application level we can do the below:
struct mqtt_sec_config *tls_config = &client->transport.tls.config;
tls_config->peer_verify = 2;
tls_config->cipher_list = NULL;
tls_config->sec_tag_list = m_sec_tags;
tls_config->sec_tag_count = ARRAY_SIZE(m_sec_tags);
tls_config->hostname = hostname;
Look forward to some suggestions here
