Digital certificates and identity cards are issued by specialized agencies. Identity cards are generally issued by the Public Security Bureau and stamped with the official seal of the issuing unit. The digital certificate protected by the Electronic Signature Law is issued by a third-party digital authentication center (CA Center for short) licensed by the state, such as Tianwei Chengxin Digital Authentication Center, which has obtained the qualification approved by the Ministry of Information Industry, to prove the validity of the digital certificate. The digital authentication center authorized by the relevant state departments has credibility on the Internet, and electronic documents such as electronic contracts and electronic orders signed with the digital certificates issued by it have legal effect.
Digital certificate mainly includes the following information: certificate version number, certificate holder information, certificate issuer (CA) information, certificate starting and ending validity period, certificate serial number, certificate issuer signature, etc. This information is similar to an ID card. The signature of the certificate issuer on the digital certificate can play an anti-counterfeiting role on the digital certificate itself, similar to the official seal on the ID card.

? Server certificate
The server certificate is installed on the server device to prove the identity of the server and encrypt communication. Server certificates can be used to prevent fake websites.
After installing the server certificate on the server, the client browser can establish an SSL connection with the server certificate, and any data transmitted on the SSL connection will be encrypted. At the same time, the browser will automatically verify whether the server certificate is valid and whether the site visited is a fake site. Websites protected by server certificates are mainly used for password login, order processing and online banking transactions. The most famous server certificate brand in the world is verisign.

Question 8: What is a personal digital certificate for online transactions? Online banking, safety first. In order to ensure security, the most effective way is to use digital certificates. Digital certificate is the fundamental guarantee of online banking security, and it is a set of mature information security protection measures widely adopted at home and abroad. So far, no case of online transaction fraud has been found because the digital certificate mechanism has been cracked. A digital certificate is your online ID card, which is an electronic file containing your identity information to prove who you are on the Internet. Digital certificate is also your security bodyguard, which can ensure the security of information transmitted online and prevent others from stealing or tampering with information. With digital certificates, you can also electronically sign online transactions and realize your online signature. When you operate in online banking, the certificate will form an electronic signature attached to the transaction instructions you send to the bank, so that the bank can identify your identity and make it impossible for others to crack and modify the information transmitted between you and the bank. With a digital certificate, you can safely use the functions of online banking. Digital certificates should be issued by an authoritative third-party security certification authority (CA), and should not be issued by banks (including e-commerce websites) as a party to the transaction. The third-party CA plays the role of avoiding risks for both parties to the transaction. For example, when there is an online banking dispute, the third-party CA can provide the corresponding certificates for both parties and clarify the responsibilities. If the customer uses the digital certificate issued by the self-built CA of the bank, it means that the bank is both a referee and an athlete. Once a dispute occurs, it is difficult to protect the legitimate rights and interests of the customer. Financial supervision departments explicitly advocate the use of digital certificates issued by third-party security certification bodies (CA). China Financial Certification Center (CFCA) is a national authoritative security certification institution approved by the People's Bank of China and the State Information Security Administration, and it is one of the important financial information security infrastructures in China. As an authoritative, reliable and impartial third-party security certification body, CFCA is responsible for providing certification services for all kinds of certification requirements in financial and non-financial fields.
