SSL digital certificate is a security protocol used to protect sensitive information during network transmission, such as credit card numbers, user names, passwords, etc. It ensures the confidentiality and integrity of data transmission by using public and private keys for encryption and decryption. The main function of an SSL digital certificate is to establish a secure connection between the client and the server to ensure that data is not stolen or tampered with during transmission. Specifically, the SSL digital certificate can verify the identity of the server and ensure that the client is connected to the correct server. It can also encrypt and decrypt the transmitted data to ensure the confidentiality and integrity of the data.
There are many SSL digital certificate products. In order to easily find the SSL certificate that suits you, SSL certificates are divided into three types according to the verification method: DV basic SSL certificate, OV enterprise SSL certificate and EV enhanced SSL certificate.

1. The DV basic SSL certificate is an entry-level SSL digital certificate, suitable not only for individual developers, but also for enterprises and institutions. Because it is an entry-level SSL digital certificate, you only need to verify domain name ownership when applying, and the certificate can be issued in a few minutes. The price of the DV basic SSL certificate is relatively low, but the functions that an SSL certificate should have are not lacking at all, such as protecting the security of transmitted data, improving SEO rankings, and increasing customer trust.
2. The OV enterprise SSL certificate is an SSL certificate specially prepared for enterprises and institutions. It only supports applications by enterprises and institutions. When applying, you need to verify the domain name ownership and the authenticity of the applicant, so it generally takes 2-36 hours to successfully review. 
The price of the OV enterprise SSL certificate is higher than the price of the DV basic SSL certificate. For example, the price of Geotrust's DV basic single domain name SSL certificate is 169 yuan, and the price of its OV enterprise single domain SSL certificate is 169 yuan.
