ssl - 服务器发送致命警报 : handshake_failure

Question

我在 https://www.ssllabs.com/ssltest/ 上运行了 ssl 证书测试我得到了很好的评价，但我看到一些设备旁边有错误，例如，在握手模拟下，Android 5.0 和 6.0 有错误消息:

Server sent fatal alert: handshake_failure

这是否意味着该网站无法在这些设备上运行，或者这是什么意思？

我的配置文件是这样的:

ssl_protocols TLSv1.2;# Requires nginx >= 1.13.0 else use TLSv1.2
ssl_prefer_server_ciphers on;
ssl_ciphers ECDHE-RSA-AES256-GCM-SHA512:DHE-RSA-AES256-GCM-SHA512:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384;
ssl_ecdh_curve secp384r1; # Requires nginx >= 1.1.0
ssl_session_timeout  10m;
ssl_session_cache shared:SSL:10m;
ssl_session_tickets off; # Requires nginx >= 1.5.9
ssl_stapling on; # Requires nginx >= 1.3.7
ssl_stapling_verify on; # Requires nginx => 1.3.7

Answer 1

ssl_ciphers ECDHE-RSA-AES256-GCM-SHA512:DHE-RSA-AES256-GCM-SHA512:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384;

Android 6 和 Android 5 均不支持这些密码。查看 SSLLabs report for Android 6.0找出支持哪些密码。特别是不支持使用 SHA384 或 SHA512 作为 HMAC 的密码。
