  • What is a digital certificate?

    A digital certificate is a document signed by a trusted CA. The certificate contains information about the public key owner and the public key file. It is a trusted credential issued by a CA to the website. The simplest certificate contains a public key, a certificate name, and a digital signature signed by a CA.

    An important feature of digital certificates is that they are only valid for a specific period of time.

  • What is SSL?

    SSL is a security protocol that implements network communication encryption. SSL establishes an encrypted channel between a browser and a website to prevent data tampering or interception during transmission.

  • What is an SSL certificate?

    An SSL certificate is a trusted certificate issued to a website by a CA, which uses the SSL protocol for communication.

    After an SSL certificate is deployed on a web server, HTTPS is enabled for the web server. Your website will transmit data through HTTPS, which helps the web server and the website establish a trusted, encrypted connection to ensure the security of data during transmission.

    For more information about the private keys of certificates, see What is a public key and a private key?.

  • What is HTTPS?

    Hypertext Transfer Protocol Secure (HTTPS) is a HTTP + SSL protocol. It is a secure version of the HTTP protocol that encrypts website communications based on the SSL protocol.

    After the SSL certificate is deployed on a website, you can enable HTTPS to activate the SSL encrypted channel (SSL protocol) between a client browser and the website server. This enables bidirectional encrypted transmission and prevents content tampering or interception.

  • What is a CA?

    CA stands for certification authority.

    As a trusted third party in an e-commerce transaction, the CA is responsible for verifying the validity of the public keys in the public key system.
