What is the difference between https and http development

Difference between HTTP and HTTPS:

The data transmitted by the HTTP protocol is unencrypted, that is, in plaintext, so it is very insecure to use the HTTP protocol to transmit private information. In order to ensure that these private data can be encrypted and transmitted, Netscape designed the SSL (Secure Sockets Layer) protocol to encrypt the data transmitted by the HTTP protocol, thus giving birth to HTTPS.

To put it simply, the HTTPS protocol is a network protocol built by SSL+HTTP protocol that can be used for encrypted transmission and identity authentication, which is more secure than the HTTP protocol.

Main Differences Between HTTPS and HTTP:

1. The HTTPS protocol needs to apply for an SSL certificate (such as GWORG CA) at the CA organization, and GWORG CA also provides a 2-year SSL certificate, and the high-level SSL certificate can display the enterprise name in the address bar.

2. HTTP is a hypertext transmission protocol, information is transmitted in plaintext, and HTTPS is an SSL encrypted transmission protocol with security.

3. HTTP and HTTPS use completely different connection methods, and the ports used are also different, HTTP is port 80, and HTTPS is port 443.

Fourth, the HTTP connection is simple and stateless; The HTTPS protocol is a network protocol built by the SSL+HTTP protocol that can carry out encrypted transmission and identity authentication, which is more secure than the HTTP protocol.

5. If you want to implement HTTPS, then you can get the SSL certificate from GWORG.

The differences between https and http are as follows:1. The URL of HTTP starts with http:, while the URL of https starts with https:.

2. HTTP is insecure, while HTTPS is secure.

3. The standard port of HTTP is 80, while the standard port of HTTPS is 4434, in the OSI network model, HTTP works at the application layer, while HTTPS works at the transport layer.

5. HTTP cannot be encrypted, while HTTPS encrypts the transmitted data.

6. HTTP does not require a certificate, while HTTPS requires an SSL certificate issued by a CA.

Difference between HTTP and HTTPS.

1.The URL of HTTP starts with http:, while the URL of https starts with https:.

2.HTTP is insecure, whereas HTTPS is secure3The standard HTTP port is 80, while the HTTPS standard port is 4434

In the OSI network model, HTTP works at the application layer, while HTTPS works at the transport layer.

5.HTTP cannot be encrypted, while HTTPS encrypts data in transit6HTTP does not require a certificate, while HTTPS requires an SSL certificate issued by a CA agency, and the SSL certificate can be deployed to the server to achieve **https encrypted access!

To put it simply, HTTPS is a secure, advanced version of HTTP. HTTP is a plaintext transmission, and HTTPS is an encrypted transmission, which is equivalent to adding a lock and is more secure. In addition, to implement HTTPS, you need to install an SSL certificate, GDCA has it, and it is also listed

The front is encrypted and unencrypted.

Hello! The differences between HTTP and HTTPS are as follows:

Web Links.

1. HTTPS is more secure than HTTPIf the data transmitted by the HTTP protocol is not encrypted, it is plaintext;

HTTPS uses SSL to communicate with HTTP, which is a network protocol HTTP+SSL that uses SSL for encrypted transmission and identity authentication, which is more secure than HTTP.

2. A CA certificate is required to use HTTPS, most of which are paid for.

CA is the abbreviation of Certificate Authority, also known as Certificate Authority Center, which also requires authorization from a third-party company.

Third, the ports are different

The HTTP URL is based on http: and uses port 80 by default;

The URL of HTTPS is started by HTTPS: and uses port 443 by default.

The differences between HTTPS and HTTP are mainly as follows:

1. The HTTPS protocol needs to apply for a certificate from the certificate authority CA, and HTTP does not need to apply for a certificate;

2. HTTP is a hypertext transmission protocol, which belongs to the information transmission at the application layer, and HTTPS is a security transmission protocol with SSL encryption, which encrypts the transmission of data, which is equivalent to an upgraded version of HTTP;

3. HTTP and HTTPS use completely different connection methods, and the ports used are also different, the former is 80, and the latter is 443.

Fourth, the HTTP connection is simple and stateless; The HTTPS protocol is a network protocol built by the SSL+HTTP protocol that can carry out encrypted transmission and identity authentication, which is more secure than the HTTP protocol.

HTTPS encrypted protocol transmission. HTTP Plaintext Transport Protocol.

Both can be accessed compatible, depending on the deployment of the web server.

HTTP stands for Hypertext Transfer Protocol, which is a data transfer protocol that specifies the rules for communicating between browsers and servers to communicate with each other and transmit World Wide Web documents over the Internet.

HTTPS stands for Hyper Text Transfer Protocol over Secure Socket Layer (Hyper Text Transfer Protocol over Secure) and is an HTTP channel with security as the goal, simply put, it is a secure version of HTTP.

Difference between HTTP and HTTPS.

1. Security is different. HTTP is a hypertext transfer protocol, and information is transmitted in clear text. HTTPS is a secure SSL certificate encrypted transport protocol. So https is more secure than HTTP.

2. The default port is different. The default port is 80 for HTTP and 443 for HTTPS.

3. The agreement is different. HTTP is a stateless protocol, while HTTPS is a network protocol built by SSL+HTTP that can be encrypted for transmission and identity authentication.

4. The cost of deployment is different. HTTP is free, HTTPS requires SSL certificates, and generally there are few free certificates, and you need to pay a fee. Therefore, the cost of https will be relatively higher.
