各位大佬，现在ssl最长买多久？

我记得以前已经说不支持多年证书了。。
但是我看还有好多网站在出售 5 年的 ssl 证书。。。

买了会怎么样? 浏览器信任吗？

找到说明了。。。 是一年一年续期

How do 2-5-year SSL Certificates Work?
  September 19, 2019   Renewal, Reissue and Refund related questions
*Maximum SSL validity period changes:
March 1, 2018 – 2 years
August 18, 2020 – 1 year

You may have noticed that if you purchase a 2*–5-year SSL certificate, the certificate you are issued is only valid for 1 year. Don’t worry, this isn’t an error.

From August 18, 2020, the maximum SSL certificate validity of an issued SSL will be limited to 1 year following new requirements announced by a number of major web browsers.

An SSL of more than 1-year is a prepay option that gets you the lowest price possible for your SSL. Buying an SSL for more years gives you a bulk discount and protects you against industry price rises.

You will still be able to use the full period you’ve paid for through the reactivation process.

多谢 。 找到了官方说明了。 是一年一年续的

现在最长就只能1年了，那些买3年5年的，都是平台会自动帮你续，不用你自己再重新买证书重新申请证书(比如套路云)
