SSL definition is a protocol, established and developed by Netscape to transfer information across the internet in a safe manner. An SSL Certificate lets visitors know that they are really doing business with you (not an impostor’s “spoof” site) thus making it easy for the web site visitor to trust you in the following ways:
- An SSL Certificate enables encryption of sensitive information during online transactions.
- Each SSL Certificate contains unique, authenticated information about the certificate owner.
- A Certificate Authority verifies the identity of the certificate owner when it is issued.
How does it work..
- A customer contacts your site and accesses a secured URL: a page secured by a Server ID (indicated by a URL that begins with “https:” instead of just “http:” or by a message from the browser).
- Your server responds, automatically sending the customer your site’s digital certificate, which authenticates your site.
- Your customer’s Web browser generates a unique “session key” (like a code) to encrypt all communications with the site.
- The user’s browser encrypts the session key with the your site’s public key so only your site can read the session key. Depending on the browser, the user may see a key icon becoming whole or a padlock closing, indicating that the session is secure.
- A secure session is now established–all communications will be encrypted and can only be decrypted by the two parties in the session. It all takes only seconds and requires no action by the user.
