Terms Used for SCM
This topic describes some terms related to Huawei Cloud SSL Certificate Manager (SCM).
Digital Certificate
A digital certificate is a file digitally signed by a CA and contains information about the owner of a public key and the public key. It is a trusted certificate issued by an authority to a website. The simplest certificate contains a public key, name, and digital signature of the CA. Another important feature of a digital certificate is that it is valid only within a specific period of time.
SSL Protocol
SSL is an encryption protocol that secures communication over a computer network. It establishes an encrypted channel between the browser and website to prevent information from being stolen or tampered with during transmission.
Certificate Authority
A Certificate Authority (CA) is an authority responsible for issuing and managing digital certificates. As a trusted third party in e-commerce transactions, the CA verifies the validity of public keys in the public key system.
HTTPS
Hypertext Transfer Protocol Secure (HTTPS) is a website encryption transmission protocol based on the SSL protocol. HTTPS activates an SSL encrypted channel between a web browser and a website server for a user to visit the website where an SSL certificate has been installed. The channel enables high-strength bidirectional encrypted transmission to prevent leakage or tampering of the data in transit. HTTPS is the secure version of HTTP.
CSR
A certificate signing request (CSR) is a message sent from an applicant to a CA to apply for an SSL certificate. A CSR file contains a public key and a distinguished name (DN). Typically, a CSR file is generated by a web server, and a pair of public and private keys are created along with the CSR file.
SSL Certificate Validity Period
From September 1, 2020, only one-year SSL certificates can be issued by CAs around the world. Therefore, the validity period of an SSL certificate you apply for through Huawei Cloud CCM is one year.
