With Taobao 、 Baidu and other websites have realized the whole station Https Encrypted access , Search engine for Https More friendly , Plus more and more people on the Internet pay attention to privacy security , Webmasters add SSL Certificates seem to be a trend .

Add... To your website SSL Certificates are not complicated , But the key point is to have one first SSL certificate . because SSL The price of the certificate is not cheap , Many personal webmasters will choose to give up using Https. however , Since open source 、 Free of charge Let's Encrypt After the certificate appears , I think SSL Is also our grassroots stationmaster can play .

The original summary of MIPO blog : Top 10 free SSL certificate : The website adds... For free HTTPS encryption


SSL Certificate level

There are three types , Domain type SSL certificate (DV SSL)、 Enterprise type SSL certificate (OVSSL)、 Enhanced SSL certificate (EVSSL)



1. Domain type SSL certificate (DV SSL - Domain Validation SSL

That is to say, the certification authority only checks the owner of the domain name online , It is usually to verify the content of a specified file under the domain name , Or verify the domain name TXT Record ;

For example, visit [http|https]://, The contents of the document : 2016082xxxxxmimvpcom2016

Or add a TXT Record –> TXT –> 20170xxxxxmimvpcom2066


2. Enterprise type SSL certificate (OV SSL - Organization Validation SSL

It is to ask the buyer to submit the organization information and the unit authorization letter etc. in the official registration certificate ,

The certification authority is issuing SSL Before certificate , It's not just about testing domain ownership ,

It is also necessary to check the authenticity and legality of these materials , Only those who have passed the verification can be issued SSL certificate .


3. Enhanced SSL certificate (EV SSL - Extended Validation SSL

And others SSL Same certificate , It's all based on SSL/TLS Security protocols ,

But the verification process is more specific and detailed , More validation steps ,

In this way, the website bound by the certificate is more reliable 、 trusted .

It's like normal SSL The difference between certificates is also obvious , Security browser's address bar turns green ,

If it's unbelievable SSL Certificates refuse to show , If it's a fishing site , The address bar turns red , To alert users .
