Digital Certificate
A digital certificate is an electronic document used to prove ownership of a public key. It acts as an online identity card, verifying the authenticity of websites, individuals, or devices and enabling secure, encrypted communication.
TECHNICAL DEFINITION
A digital certificate, often an X.509 certificate, is a cryptographic assertion within a Public Key Infrastructure (PKI) that binds a public key to an identified entity, such as a server, individual, or organization. It is issued by a Certificate Authority (CA) to enable secure communication, authentication, and non-repudiation through protocols like SSL/TLS and for digital signatures.
BACKGROUND
Computer security is a subdiscipline within the field of information security. It focuses on protecting computer software, systems, and networks from threats that can lead to unauthorized information disclosure, theft, or damage to hardware, software, or data, as well as to the disruption or misdirection of the services they provide.
