Briefly describe the 5 steps for symmetric encryption for websites

1. Your computer obtains public key of Web site to which it will connect.

2. Your computer generates a key for symmetric encryption.

3. Your computer encodes key using Web site's public key, then sends encrypted symmetric key to Web site.

4. Web site decodes symmetric key using its private key.

5. Now, your computer and Web site communicate using symmetric encryption.
