PKI- Public Key Infrastructure
What is PKI for? ā A public key infrastructure is a set of roles, policies, and procedures needed to create,
manage, distribute, use, store, and revoke digital certificates and manage public-key encryption.
PKI infrastructure- *biggest one is Certificate Authority
VA - Role that says yes, verification is good
CA -Verifies the one verifying is good
RA - Individual certificate is good
CRL- Says which ones are not good.
Certificates - Public/Private key pairs. To get one, fill out Certificate Signing Request.
o Type and length, is how the encryption is going to work.
SSL/TLS - Hoī itās used? - Certificate given to server then client, then used to exchange shared key.
PKI bypass - Make certificates free
