How SSL Works

SSL uses a cryptographic system that uses two keys to encrypt data

  • information is encrypted with a public key that is available to the public
  • a secret (private) key is used to decrypt information and only the message recipient knows it

When you put in the url of a secured domain the client and server do a handshake via SSL. The session gets a unique key and an encrypted session is established.

You will know SSL is  being used by the following indications

  • the url at the top of your browser will begin with https
  • you will see a lock symbol at the bottom of most browsers
