What is the difference between HTTPS and HTTP? How to convert HTTP to HTTPS

I do not know if you have noticed the HTTP part of the input URL, when you open the site to operate sometimes automatically jump to HTTPS format, this is why? What is the difference between HTTP and HTTPS? How to convert HTTP to HTTPS, for these problems, we did a collation.



1. What is HTTP and https?

When you enter the URL, the most common is actually the HTTP format. HTTP is the Internet's most widely used network protocol, a standard for transmitting hypertext to the local browser from the WWW Server transmission protocol, is to reduce network transmission, make the browser more efficient.

HTTPS is equivalent to the security version of the HTTP,HTTP protocol to send content in plaintext, does not provide data encryption, if the attacker intercepts the server and browser transmission between the message, you can read the information directly. And HTTPS is equivalent to the addition of SSL layer on the text, unique encryption method, the unique secret key, in order to ensure the security of its information.



2. What is the difference between the two?

What is the difference between HTTPS and HTTP ? As mentioned above, the data transmitted by HTTP is not encrypted, so it is not suitable for transmitting some sensitive information, such as credit card, password and other payment information. SSL protocol is to ensure the security of these private data transmission, it can be said that HTTPS is the SSL+HTTP protocol composed of encrypted transmission, identity Authentication network protocol. Main differences: 1) HTTP is clear text transmission, HTTPS is the security of the SSL encryption Transfer Protocol, 2) HTTPS requires a certificate to the CA, 3) HTTP and HTTPS connection method is not the same, the use of the port is not the same;

Does 3.HTTPS affect transmission speed and site ingest?

Users are most concerned about the impact of transmission speed and the site included problems.

At present, Baidu only included HTTP, Google is included at the same time included two different versions of the page, therefore, HTTPS will not affect Google's inclusion and rankings, but Baidu needs to be measured. Market needs to clear its weight, whether the security is higher than its Baidu included demand. Because of the increased encryption process, the HTTPS protocol handshake phase is indeed time-consuming, which can cause the page to load more or less approximately 50%.

4. How to do SSL authentication, switch the website to HTTPS?



The security of Internet transactions has always been a matter of concern, the SSL certification provided by Comodo is based on the global certification body, 99% of the current market on the browser has recognized Moto and its root certificate, the leading certification authority, to ensure that customers tens of thousands of transactions are safe.
After obtaining the certificate, it is clear to see that depending on the browser, a key icon becomes the whole or a padlock is turned off, indicating that the session is safe:



All communications are encrypted and can only be decrypted by both sessions. It only takes a few seconds and the user doesn't have to do anything.
