What is SSL certificate? Secure your data

The need for a secure system to send and receive data is primordial for any business. To this end, the SSL or Secure Socket Layer protocol was developed. This protocol allows any information sent to or from a browser to be encrypted, and SSL certificates were created to ensure that the company providing the transaction portal is who they say they are, as well as to prevent the malicious use of data. SSL certificates and an SSL logo on your company Web site are great ways to let customers know that their transactions are safe and secure.

SSL certificate – Secure your data

At a basic level, SSL is intended to encrypt data that is being sent from one place to another through a browser. When a browser requests a secure page for a transaction – typically denoted by the “HTTPS” tag at the beginning of a Web address – the Web server queried sends back a certificate of its authenticity along with encrypted data and a key to decrypt the information. The customer’s browser then confirms that the certificate is still valid, and uses the key provided to send back the data to the server. The server decrypts the information, and sends out requested document and HTML data.

If you ever wanted a specific directory in your website to be protected with a password, htaccess is the correct solution!

There are various methods to password protecting directories and files of your website, some server language based such as ASP, PHP, PERL and client side based, such as JavaScript. JavaScript is not as secure or foolproof as a server-side option, a server side challenge/response is always more secure than a client dependent challenge/response. htaccess is about as secure as you can or need to get in everyday life, though there are ways above and beyond even that of htaccess.
