Do I need a secure connection on regular sites?
Or what is the difference between HTTP from HTTPS.
Essentially, HTTPS is an extension of the HTTP protocol, to support encryption in order to increase security. Data in the HTTPS protocol is transmitted over cryptographic protocols such as SSL or TLS. Unlike HTTP with TCP port 80, HTTPS defaults to TCP port 443.
This is used where authorization is responsible: on payment system sites, mail services, on social networks.
On an ordinary site with the correct settings, you can also put a lock in the form of a secure connection, many like they want to fashion :)
But not many people actually need it.
And the prices for such certificates are not entirely cheap.
A separate word I want to say about online stores, in which there is an opportunity to pay for goods through payment systems.
So most of these known resources have a secure HTTPS connection !
