What the difference between all protocols and which one to use?
As you already read our topic is named "What the difference". Let's see the main features.
Only two proxy protocols are common. These are HTTP(s) and Socks5 proxies. Each is created to work with different purposes, but which one should you use and which one is better you will know after reading the article.
Socks5 is the next level of security of socks4. This protocol supports both TCP and UDP connections. TCP - a direct connection between the user and the server. It continues the connection until all data is finished exchanging. On the other side, UPD does not connect. It sends the packages instead. Socks5 does need an authentification to prevent malicious attacks.
Here are some of the advantages why Socks5 is better when the question takes online personal data protection.
Socks5 provides maximum protection to a user, but we have to admit that Socks5 provides no data encryption. Usually, this protocol is used for software.
Compared to Socks5 protocol this one has some more disadvantages and is less secure. It does not support UDP connections, but only TCP. Also, socks4 does not support authentication as socks5 does.
Pros of using Socks4 Protocol
Cons of using Socks4 Proxy protocol
The HTTPs protocol was created for HTTP traffic, and "s" means a higher level of protection than common HTTP has, but their functionality is the same. It supports only TCP connection. This protocol is the most popular. The use of it is simply browsing the Internet or to unblock some of the restricted websites.
It supports the HTTPs connection depends on the proxy server type. This will encrypt your data between the client and the server.
It is possible to find free servers, but we could put this "pro" into the "con", cause the free servers are 100% unsafe, has a low-speed connection, many of such proxies are used by millions of people at the same time. So the option is to buy the HTTPs and Socks5 proxy server from the Proxy-Seller - it is fully the opposite of listed cons and that's why it becomes into "pros".
UDP protocol is not supported. So that's why many users that are working with the software are choosing Socks5 proxies.
So, you know the difference now, and the only one who will make a choice is you.
