A standard that defines the format of public key certificates used in many Internet protocols, including TLS and SSL.
X.509 is a standard that defines the format of public key certificates. These certificates are used in many Internet protocols, including TLS and SSL, to provide secure communications. In cloud computing, X.509 certificates are used to secure communications between services and users.
X.509 works by providing a standard format for public key certificates. These certificates contain a public key and an identity (a hostname, or an organization, or an individual), and are either signed by a certificate authority or self-signed.
A cloud service provider, CloudServe, uses X.509 certificates to secure communications between their cloud services and their customers. When a customer connects to a CloudServe service, the service presents an X.509 certificate. The customer can then verify the certificate and establish a secure communication channel.
A pair of cryptographic keys used for encryption and decryption or to create digital signatures.
