I want to add more cipher suites. I use NWConnection to make a connection. Before I use sec_protocol_options_append_tls_ciphersuite method to add more cipher suites, I found that Apple provided 20 cipher suites shown in the client hello packet. But after I added three more cipher suites, I found that nothing changed, and still original 20 cipher suites shown in the client hello packet when I made a new connection.
The following is the code about connection. I want to add three more cipher suites: tls_ciphersuite_t.ECDHE_ECDSA_WITH_AES_128_CBC_SHA256, tls_ciphersuite_t.ECDHE_ECDSA_WITH_AES_256_CBC_SHA384, tls_ciphersuite_t.ECDHE_RSA_WITH_AES_256_CBC_SHA384
Can you give me some advice about how to add more cipher suites? Thanks.
By the way, I working on a MacOS app. Xcode version: 16 MacOS version: 15.6
