Explanation:
PKI is a two-key, asymmetric system with four main components: certificate authority (CA), registration
authority (RA), RSA (the encryption algorithm), and digital certificates. In typical public key infrastructure (PKI)
arrangements, a digital signature from a certificate authority (CA) attests that a particular public key certificate is
valid (i.e., contains correct information). Users, or their software on their behalf, check that the private key used
to sign some certificate matches the public key in the CA’s certificate. Since CA certificates are often signed by
other, “higher-ranking,” CAs, there must necessarily be a highest CA, which provides the ultimate in attestation
authority in that particular PKI scheme.
Localhost is a hostname that means this computer and may be used to access the computer’s own network
services via its loopback network interface. Using the loopback interface bypasses local network interface
hardware. In this case the HTTPS://127.0.01 was used and not HTTPS//localhost
