When we access**, we generally need to access through two forms, one is through the domain name, and the other is through the IP address. If they want to upgrade to the HTTPS protocol, they can't do without SSL certificates and IP certificates. SSL certificates and IP certificates have become an important part of network security, yet many people are unclear about the difference between them. This article will cover the differences between the two.
An SSL certificate is a digital certificate used to encrypt and verify security. It digitally signs the public key provided by the user by using SSL technology to ensure that the communication between the user and the user is encrypted and secure. SSL certificates are used to ensure authenticity and security, providing users with a secure experience.
An IP certificate is a digital certificate that is used to verify and secure an IP address. It ensures the authenticity and legitimacy of an IP address by linking it with the identity information of its owner. IP certificates play an important role in network communication and security, especially in cloud computing and virtualization environments, providing a higher level of security.
While SSL certificates and IP certificates are both digital certificates, there are some differences between them:
1. The object of application is different. The SSL certificate of the domain name is based on the domain name application, and the protection of the domain name type ** realizes HTTPS encryptionThe IP certificate is applied based on the IP address (must be a public IP address), and the IP address is protected** to implement HTTPS encryption.
2. The brands and types that can be selected are different. At present, there are many CA organizations that can provide SSL certificates for domain names, and the types it can choose from are also relatively rich, which can basically meet the needs of users from all walks of lifeAt present, there are not many brands to choose from for IP certificates, Digicert and Comodo, and there are only two types of them, single IP and multi-IP.
3. The conditions are different. There are basically no restrictions on the SSL certificate of the domain name, as long as it is a regular domain name, you can apply for it;There are many restrictions on IP certificates, such as the public IP address, the applicant has the right to use or manage the IP address, the ownership can only be verified through file verification, and the wildcard of the IP segment is not supported.
To sum up, IP certificates and SSL certificates essentially provide information transmission encryption and identity services, and understanding the differences and functions between them can help you choose the right certificate to ensure the security of network communication and resources.
