What is the difference between HTTP and HTTPS? A case makes it clear that they are actually very similar.
In our work, we often see the shadow of https, such as Baidu, which has a small lock mark in the address bar, such as WeChat payment callback verification, etc., but we don’t know the difference between it and http, Xiaowu is also Recently, I have come into contact with several cases where the https security protocol is used, so I have a relatively clear understanding of this, so what exactly is it?
There's little to no feeling in use of either when you're going through a website visit. However, there are some differences between them.
First of all, HTTP is abbreviated as "Hypertext Transfer Protocol" , and HTTPS is its secure version, where "S" stands for "secure". It can be said that HTTPS is more secure than HTTP.
So how does this security manifest itself?
We can say that HTTPS is like you are buying things with cash, and then put on an extra layer of anti-theft chain when paying to ensure that the cashier will not mess around when collecting money;
HTTP is like you only take If you forget to activate the “password input” function in the store, you may be easily stolen by malicious software passing by when you enter your password, or you may be poked by that thumb and enter the wrong password once in a hurry.
Through HTTPS, the transmitted data is encrypted , and others cannot see the data transmitted between you and the website. It's like you are playing the guitar under the bridge, and others can't hear what you are playing.
At the same time, in HTTPS, the identity of the website is verified through the certificate. What you visit is a real website, not a malicious virus website, just like you ask the other party to show their ID card to verify their identity information.
Having said so much, the glory of "S" is not given in vain, but is protected by a series of complex security certificates, encryption methods, verification codes , etc., so as long as you are on an HTTPS website, it is more secure than HTTP. more trustworthy.
To sum up, HTTP and HTTPS are like two similar dog tails. HTTP can only express, while HTTPS can also keep secret and verify identity. With the appearance of "S", the world becomes safe; without "S", safety becomes a dream.
