RABA Services SSL

Ever wondered why there are some website that starts with http and some with https? That extra ‘s’ indicated that you are browsing the website through ‘secure’ connection.

Secure Socket Layer or in short SSL certificates is a part of HTTPS protocol. or more specifically, a security protocol. Protocols describe how algorithms should be used. In this case, the SSL protocol determines variables of the encryption for both the link and the data being transmitted.

All browsers have the capability to interact with secured web servers using the SSL protocol. However, the browser and the server need what is called an SSL Certificate to be able to establish a secure connection.

When a browser attempts to access a website that is secured by SSL, the browser and the web server establish an SSL connection using a process called an “SSL Handshake”. Three keys are used to set up the SSL connection: the public, private, and session keys. Anything encrypted with the public key can only be decrypted with the private key, and vice versa.

Because encrypting and decrypting with private and public key takes a lot of processing power, they are only used during the SSL Handshake to create a symmetric session key. After the secure connection is made, the session key is used to encrypt all transmitted data.


RABA Services Secure Connection

    1. Browser connects to a web server (website) secured with SSL (https). Browser requests that the server identify itself.
    2. Server sends a copy of its SSL Certificate, including the server’s public key.
    3. Browser checks the certificate root against a list of trusted CAs and that the certificate is unexpired, unrevoked, and that its common name is valid for the website that it is connecting to. If the browser trusts the certificate, it creates, encrypts, and sends back a symmetric session key using the server’s public key.
    4. Server decrypts the symmetric session key using its private key and sends back an acknowledgement encrypted with the session key to start the encrypted session.
    5. Server and Browser now encrypt all transmitted data with the session key.


Websites that uses SSL / HTTPS ensure that their visitors information are encrypted and also earn better rank in search engine – Currently, google has started to de-rank website that does not have SSL installed. You might see some of your favorite website which still does not have SSL installed to rank lower than usual.
