What is Certificates?
Certificates, also known as digital certificates or SSL/TLS certificates, are electronic documents used to establish trust and secure communication over networks. They function like digital IDs, verifying the identity of websites, servers, individuals, or devices. These certificates contain information about the entity they represent, a digital signature from a trusted Certificate Authority (CA), and the entity's public key, which is used for encryption and secure data exchange.
