In-depth analysis of SSL digital certificates to protect corporate websites

An SSL certificate is a type of digital certificate. It complies with the SSL protocol and is issued by a trusted digital certificate authority (CA) after verifying the server's identity. It has server identity authentication and data transmission encryption functions.

Certificate functions:

• Information encryption: Ensure the privacy and confidentiality of users when they log in to the website to shop online or conduct various transactions. Trusted websites will help you establish a secure encrypted channel for information transmission.
• Identity identification: Confirm the authenticity of the website. There are many fake and phishing websites on the Internet. How can users judge the authenticity of the website and how can they trust the website they are visiting? Trusted websites will help users confirm the identity of the website.

Why You Need an SSL Certificate

Security - Encryption of transmitted information to prevent it from being intercepted. Basic requirement for credit card transaction websites.

The National Security Law requires website owners to ensure the security of registered user information. SSL certificates should be the most basic requirement

Apple APP requires all APPs to use SSL, but it has not been officially implemented

Search engines such as Google and Baidu give priority to displaying websites with https

When installing software without a code signing certificate, Windows and other operating systems will prompt that it is unsafe or cannot be installed.

With the prevalence of e-commerce, the CA center, the issuing agency of digital signatures, will provide reliable security guarantee for the development of e-commerce.

If your website uses an SSL certificate and displays the seal, your customers know that their transactions are safe and secure, and they can fully trust your website.

Which SSL certificate is best for corporate websites?

Domain Validation Certificate (DV)

It ensures that the confidential information of the website is transmitted from the user's browser to the server with high-strength encryption and will not be illegally stolen or tampered with. You only need to prove that the domain name you want to protect is yours to pass the review of the certificate authority (CA). The issuance speed of domain name verification is fast, but because almost everyone can get a DV certificate, the trust level is low.

Organization Validation Certificate (OV)

It is a more advanced and better SSL certificate that needs to verify the true identity of the website owner. It is different from the Domain Validation (DV) certificate in that it requires some additional review to ensure that you not only own your own domain name, but also that your company and organization are legitimate. Organization Validation (OV) can not only encrypt the confidential information of the website, but also prove the true identity of the website to users.

Extended Validation Certificate (EV)

Refers to a certificate that can only be issued after passing a high-level identity review by an enterprise or organization. The certificate authority will verify the authenticity of the applicant's organization name, address, telephone number, bank account and other information. It usually takes 2-5 working days to review the information. The extended validation certificate has the highest level of encryption security and displays the company or organization name in the browser address bar, making it easier for users to identify fake websites.

Before applying for OV and EV certificates, the company's qualifications must be confirmed.

You can apply for a DV certificate as an enterprise or a personal website, but you must be an enterprise to apply for an OV or EV certificate. After the customer submits the application form, he/she should first go to Whois, Dun & Bradstreet or Enterprise Trust Network to check the relevant information.

DV certificate, verification is very simple, only need to verify the domain name ownership. There are generally two verification methods, email verification and file verification.

• Email verification: Generally, the CA sends a verification email to the customer's administrator's general email address or whois email address.
• File verification: Generally, you need to upload files to the server.

There are also free SSL certificates, but the security is not that high.
