What are the types of digital certificates?

OV Certificate: The certificate of enterprise identity verification: You need to submit valid enterprise qualifications such as the business license of the enterprise. Suitable for enterprises and institutions.

The DV and OV address bars are displayed in the same way.

The OV certificate displays the real-name registration information of the enterprise.

EV Certificate: Enhanced Validation Certificate: It is necessary to submit valid enterprise qualifications such as business license for the most stringent verification.

It is the highest level of SSL certificate. The browser address bar is marked green and displays the name of the company that has passed the certification. It is suitable for Internet companies, large-scale enterprises, finance, insurance and other industries.

There are four main types of digital certificates:

1. Personal digital certificate: The certificate contains personal identity information and the public key of the personal circle, which is used to identify the personal identity of the certificate holder.

2. Institution digital knowledge and dispersion certificate: The certificate contains the public key mining rules and enterprise information of the enterprise, which is used to identify the identity of the certificate holding enterprise.

3. Personal signature certificate: The certificate contains the personal signing private key and personal identity information, which is used to identify the personal identity of the certificate holder.

4. Organization signing certificate: The certificate contains the enterprise's signature private key and enterprise information, which is used to identify the identity of the certificate holder.

Types of digital certificates:

1. Personal digital certificate: It is a virtual world identity issued by an authoritative organization, which is composed of a string of corresponding data, including unique attributes of the bridge, such as ID card, etc., which can be bound to the entity for identification;

3. Signing certificate: It is an ideal solution for software developers to enable software developers to digitally sign their software;

4. SSL certificate: mainly used for server data transmission link encryption and identity authentication, binding ** domain name, different products for different value data and different identity authentication;

Digital certificate: It is a string of numbers that mark the identity information of all parties to the communication in Internet communication, providing a way to verify the identity of the communication entity on the Internet.

Digital certificate: It is a string of numbers in the Internet communication that signs the identity information of all parties to the promotion, providing a way to verify the identity of the communication entity on the Internet.

Everyone has many forms of identification, such as ID cards, driver's licenses, passports, etc., these documents are stamped and certified by the corresponding issuing authority, with a high degree of credibility, it is difficult to forge, and with the development of science and technology, it can also be authenticated through fingerprints, retinas and other biometrics. A digital certificate, also known as an electronic certificate, is similar to an ID card in daily life, and is also another form of identity authentication used to identify the identity of a user in a network. The digital certificate is a collection of a variety of cryptography encryption algorithms, the certificate itself has public key information, can complete the corresponding encryption and decryption operations, and at the same time, it also has the digital signature of its own information, which can identify the issuing authority of the certificate and the integrity of the certificate content.

Since the certificate itself contains the user's authentication information, it can be used as the basis for user identification. Generally, a digital certificate will contain the following contents: the name of the object (person, server, organization); The expiration time of the certificate; the issuing authority of the certificate (who is the guarantor of the certificate); The digital signature of the certificate authority on the certificate information; Signature algorithm; • The public key of the object.

The name of the object refers to the user represented by the certificate, which can be a person, server, organization, and so on. The expiration time of a certificate is used to determine whether the certificate is still valid. The issuing authority will guarantee the authenticity and validity of the certificate and ensure that the information carried by the certificate has been verified.

The digital signature is used to identify the issuer of the certificate and whether the content of the certificate is complete, the issuer signs the certificate with the private key, and the verifier uses the public key of the issuer to decrypt the signature, and compares it with the digest generated by the digest algorithm to verify whether the certificate is issued by the authority and whether the information is complete. The object's public key is used to encrypt the information, and the information is transmitted to the receiver, who will use the private key corresponding to the public key for decryption.

A digital certificate is an electronic document, which is a string of numbers that can indicate the identity information of a network user, and provides a way to verify the identity of a network user on a computer network, so a digital certificate is also called a digital identity.

A digital certificate refers to an electronic document issued by a CA organization, which is a string of numbers that can indicate the identity information of network users, and provides a way to verify the identity of network users on a computer network, so digital certificates are also called digital identifications.

A digital certificate is a string of numbers that mark the identity information of all parties to the communication in Internet communication, providing a way to verify the identity of the communication entity on the Internet, and the digital certificate is not a digital ID, but a seal or seal (or a signature added to the digital ID) stamped by the identity authentication authority on the digital ID.

It is issued by an authoritative authority, the CA, also known as the Certificate Authority, and people can use it to identify each other online.

A digital certificate is an authoritative electronic document, which can be issued by an authoritative and impartial third-party organization, that is, a CA (such as a CA company in various parts of China) center, or an enterprise-level CA system.
