PKI
KPI
How does PKI work?
- Server public key (Asymmetric key) sent to client
- Client uses its private key to encrypt webpage key (asymmetric Key)
- Cipher text sent to server
- Server decrypts with public key (symmetric).
- Server now has safe webpage.
- Client and server agree on a key (Symmetric Key)
- Key sent so both have copy
- Client encrypts website with credentials and sends cipher to Server (symmetric key)
- Server now decrypts with given shared private key (symmetric)
- Server can encrypt anything with the same private (symmetric) key and send back to the client
- Server public key (Asymmetric key) sent to client
- Client uses the given key to encrypt session key (symmetric Key)
- Cipher text sent to server
- Server decrypts with private key (asymmetric key).
- Both now have session key to communicate safely, and quickly.
Why use HTTPS?
a. Increases user’s trust and confidence
