Personal digital certificate is a virtual world identity issued by an authoritative organization.

After the application for a personal digital certificate is completed, you need to follow the application process for a personal digital certificate in order to successfully obtain the digital certificate. Digital certificates have many functions. They can be used to keep information confidential, because the confidentiality of information is very important in the information transaction process and has a great impact on users. Digital certificates can also confirm the identity of traders to a certain extent.

Characteristics of personal digital certificates

1. Identity authentication: The two parties transmitting information on the network cannot meet each other. The use of digital certificates can confirm the identities of both parties, rather than being impersonated by others.

2. Confidentiality: By using a digital certificate to encrypt information, only the recipient can read the encrypted information, thus ensuring that the information will not be stolen by others.

3. Integrity: Digital certificates can be used to verify whether the transmitted information has been tampered with or lost during the transmission process.

4. Non-repudiation: Digital signatures using digital certificates have the same legal effect as handwritten signatures.
