/// TLSv1.3 support requires at least OpenSSL version 1.1.1.
/// In order to enable TLSv1.3 support, specify TLSV1_3_CLIENT_USE

/// - TLS_AES_256_GCM_SHA384
/// - TLS_CHACHA20_POLY1305_SHA256
/// - TLS_AES_128_GCM_SHA256
/// - TLS_AES_128_CCM_8_SHA256
/// - TLS_AES_128_CCM_SHA256
///
/// The first three of the above cipher suites should be enabled
/// by default in OpenSSL if you do not provide an explicit
/// cipher configuration (cipherList).
