The type of SSL certificate of an SSL security certificate

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 many types of SSL certificates, which are classified as follows:

SSL certificates can be classified into single-domain name certificates, multi-domain name certificates, and wildcard certificates based on the number and types of domain names supported.

1) Single-domain SSL certificate: According to the literal meaning, it is an ordinary SSL certificate that only protects one domain name, which can be a top-level domain name or a second-level domain name.

2) Multi-domain SSL certificate: It is also the same as the literal meaning, that is, it can protect multiple domain names at the same time, whether it is the main domain name or a sub-domain name, it can generally protect 2 250 domain names, when you have a new domain name to protect, you can add it at any time, if you exceed the number of protection, you need to pay a certain amount of additional fees, but it is much more cost-effective than re-applying for an SSL certificate, and it also saves the time for re-review.

3) Wildcard SSL certificate: It is able to protect a domain name and all the subordinate domain names of the domain name, with a scope limit, but no quantitative limit, suitable for users with a large number of second-level domain names.

According to the verification method, SSL certificates can be divided into: DV certificate (domain name verification), OV certificate (enterprise verification), and EV certificate (extended verification).

1) DV SSL certificate: It is also a domain name verification certificate, when applying for this certificate, CA (Certificate Authority) only needs to review the ownership of the domain name, the whole process is very simple, no manual work, and the system automatically completes it. Therefore, the time is relatively fast, generally about 10 minutes can be issued, and **cheaper, relatively speaking, the level is also relatively low, suitable for individuals** and small organizations or enterprises**.

2) OV SSL certificate: This is an enterprise verification type, which has higher verification requirements than DV certificates. It not only needs to verify the ownership of the domain name, but also needs to verify the identity of the enterprise, the verification is to provide enterprise information and scanned copies of the company's business license, etc., all of which are manually reviewed, and generally take 3-5 working days to be issued, ** is relatively high, but the security level has been greatly improved, suitable for general organizations or small and medium-sized enterprises**.

3) EV SSL Certificate: This is currently the highest level of security certificate in the industry, and the functions are more powerful than the first two. If the user has installed this certificate, the browser will not only display the green address bar with the https prefix and lock logo, but also the company name, which not only looks very tall, but also really more secure.

Of course, the EV SSL certificate review is also the most stringent, you need to provide enterprise information and company business license scanned copies and other information, as well as Dun & Bradstreet or a lawyer's opinion letter, the CA agency will manually verify the organization and ** information, generally 3-7 working days to issue, ** is also relatively high, suitable for ** transactions**, large enterprises or finance, banks and other organizations.

According to the security strength of SSL, CA generally divides SSL certificates into 5 types:

DVSSL: SSL is a domain-based SSL security certificate that can be issued quickly without manual review.

OVSS: an enterprise-type SSL security certificate that needs to be manually reviewed and contains enterprise authentication information.

There are three types of SSL certificates on the market, namely Domain Validation (DV), Organization Validation (OV), and Extended Validation (EV).

DV SSL certificate (domain name validated)

The DV SSL certificate is the very cheap one of all SSL certificates. Since its verification process is less rigorous, it is easy to obtain. Owners who apply for a DV SSL certificate only need to prove to the certificate authority that they are the legitimate owner of the domain name, which can be obtained through document verification, email, or CNAME.

OV SSL certificate (Enterprise Validated)

The review process of the OV SSL certificate is more thorough as compared to the DV SSL certificate. In addition to determining domain ownership, the certificate authority also checks whether the business organization applying for the certificate is legitimate. Once the certificate is issued, the business information will be displayed in the subject line of the details section, which will make the business appear more credible and legitimate in the eyes of the visitor.

EV SSL Certificate (Extended Validation Type)

EV SSL certificates provide the highest level of proof of legitimacy and are validated more rigorously than OV SSL certificates. The Certificate Authority will conduct an extensive background check to confirm the physical address, legal status, and order details of the company applying for the certificate.

In addition, SSL certificates can be divided into single-domain SSL certificates, multi-domain SSL certificates, and wildcard SSL certificates according to the number of protected domain names.

1. Classification of SSL certificates.

1. Extended Validation EVSSL Certificate;

2. Organization verification OVSSL certificate;

3. Personal verification IVSSL certificate;

4. Domain name verification DVSSL certificate;

2. Brief description of SSL certificate.

1. SSL certificate is a type of digital certificate, similar to an electronic copy of a driver's license, passport, and business license. Because it is configured on the server, it is also known as an SSL server certificate;

2. SSL certificate is issued by a trusted digital certificate authority CA after verifying the server identity, and has the functions of server authentication and data transmission encryption.

3. The SSL certificate establishes an SSL security channel between the client browser and the web server. This security protocol is mainly used to provide authentication to users and servers; encrypt and hide the transmitted data; Ensuring that data is not altered in transmission, i.e. data integrity, is now a global standard in this field;

Third, the role of the certificate.

1. Encrypt the transmission of data.

When the user accesses ** through the HTTP protocol, the browser and the server are transmitted in plaintext, which means that the password, account number, transaction records and other confidential information filled in by the user are in plaintext, which may be leaked, stolen, tampered with and used by hackers at any time;

2. Authenticate the identity of the server.

Phishing scams are rampant, how can users identify if it's phishing or safety? **After deploying the globally trusted SSL certificate, the browser has a built-in security mechanism to check the certificate status in real time, and display the identity authentication information to the user through the browser display security lock, green address bar, organization name, certificate information, etc., so that the user can easily identify the real identity and prevent phishing.

According to the degree of encryption, it can be divided into three types of certificates: DV, OV and EV.

DV SSL certificateIt only verifies the domain name, and does not verify the authenticity of the applicant's identity, so it only has the function of data transmission encryption, and does not have the function of verifying the identity of the applicant.

OV Certificate,At the same time, the identity of the domain name and the applicant is verified, which has the dual functions of data transmission encryption and authenticity verification.

EV Certificate,Same as the OV certificate function, only the green URL and organization name are added to the display, which is more authoritative.

According to the number of supported domain names, it can be divided into three types: single-domain name certificates, multi-domain name certificates, and wildcard certificates.

Single-domain name certificatesAs the name suggests, only a single domain name is supported;

Multi-domain certificates,Support multiple domain names, regardless of whether the main domain name or subdomain name is differentiated;

Wildcard certificates,Multiple subdomains under the same primary domain name are supported.

What is an SSL security certificate, which most people do not understand. However, when we browse **, we often encounter the situation that the browser has a security certificate. In fact, the security certificate refers to the SSL certificate, so what is the SSL security certificate, let's take a look at it specifically.

SSL certificates provide a way to authenticate on the Internet and are digital information files that are used to identify and prove the identities of both parties to a communication. The use of SSL certificate can ensure the confidentiality of information exchange between users and servers, and has the functions of non-eavesdropping, non-changing, non-repudiation, and non-impersonation. SSL certificates are issued by a "trusted root certification authority" in the browser after verifying the identity of the server, and have the dual functions of authentication and encrypted transmission.

When the SSL certificate is added, both Google and Firefox are displayed as safe and trustworthy, so that users do not have to worry about whether there is a virus in their browsing and increase the number of clicks.

In fact, the SSL certificate refers to the security certificate, because the nature of SSL is a security protocol, so it can also be called an SSL security certificate. SSL, on the other hand, was originally established as an international global standard for confirming security and encrypted communication between browser users and web servers. Moreover, SSL's technology has been used in most of the world, so many of them now need to configure security certificates.

This is also the reason why SSL calls it a security certificate, which provides a transport layer security application protocol to solve the problem of identity identification, confidential and private information encryption transmission of Internet services. However, the application process is very important in the configuration of SSL, and deciding which SSL security certificate to purchase is not only a technical issue, but also involves a series of issues such as the company's strategy, service awareness, and management. However, if there is no lock symbol, it means that the information you are entering may be illegally stolen and leaked during the network transmission submitted to the server, and it is recommended that you refuse to submit any information that you think needs to be kept confidential on the ** that does not display the security lock, so as to ensure that your confidential information will not be leaked.

The SSL security certificate is installed on the first to upgrade HTTP to the HTTPS encryption protocol, protect the data security from being stolen, maintain the integrity of the data, and ensure that the data is not changed during transmission.

1. Data encrypted transmission: After HTTPS encryption is realized, an encrypted channel will be established from the user end to the first server side to ensure that the data is not stolen or tampered with by a third party, and to protect the security of user accounts, passwords and transaction data.

3. Prevent traffic hijacking: effectively solve the problem of traffic hijacking of search engines and major sites, and prevent the occurrence of problems such as the tampering of the search results page and the forced insertion of pop-up windows or embedded advertisements in the returned content.

SSL certificates are bound to domain names, and in general, one domain name corresponds to one SSL certificate, and only wildcard certificates and multi-domain certificates support multiple domain names.

Single-domain: You only need to use an SSL certificate for a single domain name, you can choose any WoSign SSL certificate, buy it, give it away, and vice versa.

Multi-domain: A multi-domain SSL certificate supports any domain name. You have multiple domain names with completely different TLDs that require an SSL certificate (e.g

Please select the SSL certificate type that supports multiple domain names, all SoftTone SSL certificate products support multiple domain names, up to 100 domain names.

Wildcard: Wildcard certificates support only *Wildcard subdomains.

If you have multiple subdomains with the same top-level domain name and need to use SSL certificates, please select the SSL certificate that supports wildcard domain names.

Magnum: A universal SSL certificate supports a mix of multiple domain names and wildcard domain names. Both multi-domain and wildcard domain names require an SSL certificate (e.g

Please select the SSL certificate that supports universal domain names, WoSign ZhenOV SSL certificate supports universal domain names.

If the problem encountered by the user cannot be solved, the customer service on the official website of wosign can seek help web link.

According to the number of applicable domain names, there are wildcard SSL certificates, universal SSL certificates, single-domain SSL certificates, and multi-domain SSL certificates.

Wildcard SSL certificates: also known as wildcard domain name certificates, can be applied to multiple subdomain names at the same time, and can match *.

Universal SSL certificates: You can bind different mixed domain names to a single SSL certificate, not only wildcard *It also supports 1-100 different domain names.

Single-domain SSL certificate: can be applied to only one domain name.

Multi-domain SSL certificates: can be applied to multiple different domain names.

According to the certificate certification level, there are DV SSL certificates, IV SSL certificates, OV SSL certificates, and EV SSL certificates.

DV is the abbreviation of Domain Validation, and the DV SSL certificate refers to a simple SSL certificate that only needs to verify the ownership of the domain name. The DV SSL certificate can only encrypt the transmission information and cannot verify the real identity of the site server. The advantage of DV is that it is cheap, the application is fast, and the review can be completed in a few minutes, and most of them are used by individuals.

IV is the abbreviation of Individuals Validation, and IV SSL certificate refers to a professional-level (Class 2) SSL certificate that needs to verify the real identity of the operator. Currently, only WoSign CA provides IV SSL certificate issuance.

OV is the abbreviation of Organization Validation, and the OV SSL certificate refers to the standard SSL certificate that needs to verify the real identity of the organization. This certificate can not only complete the encryption of the transmitted data, but also verify the real identity of the server, which is more secure and credible than the DV SSL certificate, and the security insurance will be higher. At the same time, the audit will be more rigorous and the audit cycle will be longer.

Generally, it is mostly used in e-commerce, education, games and other fields.

EV is the abbreviation of Extended Validation, and EV SSL certificate refers to an SSL certificate issued in accordance with the world's unified strict authentication standards, which is currently the world's highest-level SSL certificate. If you have an EV SSL certificate deployed, the address bar of your browser will be green when you access it. It is mostly used in financial payment, online banking and other fields.
