A server certificate, also known as an SSL certificate, is used to verify the identity of a server and establish a secure, encrypted connection between a server and a client. It is issued by a trusted Certificate Authority (CA) and contains information such as the server’s domain name, public key, expiration date, and the CA’s digital signature.
On the other hand, a client certificate is used to verify the identity of a client and grant them access to specific resources, such as secure websites or networks. It is also issued by a trusted CA and contains information about the client’s identity, public key, and the CA’s digital signature.
In summary, a server certificate is used to secure the communication between a server and a client, while a client certificate is used to verify the identity of a client and grant them access to specific resources.
