The client automatically saves any new server public keys. In subsequent connections, the 
server public key is checked against the saved version on the client computer.
Encryption Method
Once the identification is verified, both the client and server must agree on the type of 
encryption method to use.
Authentication and Data Transmission
After the identification is verified and data encryption activated, a secure tunnel is established 
between the client and the server. The client then sends its authentication information (user 
name and password) to the server to log in to the server.
