openssl 去驗證是否支援 TLS 1.2、1.3，可以使用 openssl s_client 來做檢測~

• 詳見：man openssl-s_client
  • -ssl3, -tls1, -tls1_1, -tls1_2, -tls1_3, -no_ssl3, -no_tls1, -no_tls1_1, -no_tls1_2, -no_tls1_3
    • These options require or disable the use of the specified SSL or TLS protocols. When a specific TLS version is required, only that version will be offered or accepted.
    • Only one specific protocol can be given and it cannot be combined with any of the no_ options. The no_* options do not work with s_time and ciphers commands but work with s_client and s_server commands.
