检测浏览器TLS兼容性 [英] Detect browser TLS compatibility
问题描述
我们有一个SSL网站,主机最近禁用了较旧的SSL协议,如TLS 1.0及更低版本。如果浏览器使用的浏览器至少不支持TLS 1.1,则网站访问者在访问网站时会看到空白页或隐藏的错误消息,具体取决于浏览器。
We have a SSL website where the host has recently disabled older SSL protocols like TLS 1.0 and below. Depending on the browser, the site visitor gets a blank page or a cryptic error message when they visit the site if the browser they are using does not support at least TLS 1.1.
我希望创建一个不在SSL端口上的登录页面,如果它支持TLS 1.1及更高版本,我可以检测浏览器功能。如果没有,那么我想向他们展示一个友好的消息,以升级他们的浏览器或使用不同的浏览器。
I was hoping to create a landing page that is not on the SSL port and where I can detect the browser capability if it supports TLS 1.1 and above. If it doesn't then I want to show them a friendly message to upgrade their browser or use a different browser.
这是否可以使用客户端javascript完成图书馆?如果是这样,那么我应该使用什么。
Is this something that can be accomplished using client side javascript library? If so, then what should I be using.
谢谢。
推荐答案
您可以使用 API .howsmyssl.comrel =noreferrer>我的SSL怎么样?。
You can use the API provided by How's my SSL?.
在下面的例子中,我检查 tls_version
。检查 given_cipher_suites
也可能是一个好主意。
In the following example, I check the tls_version
. Checking given_cipher_suites
may also be a good idea.
<script>
window.parseTLSinfo = function(data) {
var version = data.tls_version.split(' ');
console.log(
version[0] != 'TLS' || version[1] < 1.2
? 'So bad! Your browser only supports ' + data.tls_version + '. Please upgrade to a browser with TLS 1.2 support.'
: 'All OK. Your browser supports ' + data.tls_version + '.'
);
console.log(data);
};
</script>
