Are you running your own software or online business platform? If yes, then you probably know that the most important aspect of any software or online business is trustworthiness. If you are able to create an environment where your potential customers will feel confident and safe about providing their private information and making a purchase, then be rest assured that your business will thrive. This is where the Secure Socket Layer, popularly known as SSL certificate, comes into play. SSL ensures that your users trust you whole-heartedly. Simply put, SSL certificate is all about encrypted communication and establishing trust. It is a standard security technology used in the building of a secure connection between clients and servers; it also serves as a way of protecting your data from cybercriminals. It may be a connection between a web server and a browser or a mail server and a mail client. SSL allows for the secure transmission of Personally Identifiable Information, such as credit card IDs or login credentials. Most of the data on the internet is sent in plain text, therefore being vulnerable to cyber-attacks. To be specific, SSL certificate is a security protocol (Protocol is a set of rules allowing two endpoints to communicate with each other). Thanks to this protocol, millions of users in today's world are now able to enter their information and send it via the internet without worrying about the security of their data. However, there's a question that a lot of users would like an answer to, and the question is how do users differentiate between a secured connection and one that's unsecured? The answer is actually very simple. Your browser will provide you with visual cues such as a lock icon or a green bar. These icons and bars are there to let a user know that their connection is secured. And just in case you are facing a security threat, the red icon appears in your browser bar.


We're guessing you now know a little about the SSL certificate, now let's take a closer look at how the protocol works so as to be able to have a better understanding of why this component is important. Now, when a software is getting prepared to be run on an encrypted browser, a process known as the "SSL Handshake" is started. In order to set up an SSL connection, three different types of keys are used, and they are:
  • Public keys
  • Private keys
  • Session keys.
Any data that was initially encrypted with public keys can only be decrypted by private keys. Session keys, on the other hand, are used by both browsers and servers to encrypt each and every transmitted data. Let's take a closer look at the encryption process: Client Says Hello To The Server - The browser connects to the server and determines its security level. It checks whether the server is secured with SSL and demands identification from the server. Server Says Hello To Client - Servers send the browser a sample of the SSL certificate it is equipped with; this sample is where the information about the server's public key is included. Time For Authentication Process Or Semi-Secure - Browser checks the certificate ID against a list of trusted CA (Certificate Authority) and the validity of the certificate. If the results turn out positive, the browser creates, encrypts, and sends back a symmetric session key using the server's public key. Decryption Or Master Secure - Server decrypts the symmetric session key using its private key, then sends back an acknowledgment which is encrypted with the session key. Encryption With Session Key - Server and browser exchange messages, informing each other that every future data exchange will be encrypted with the session key.


SSL Encrypts Sensitive Information - Every piece of data that is transmitted across the internet travels from one computer to another before finding its way to its final destination. If you don't make use of an SSL encryption, any computer between a user and the server hosting your software will be able to access your information. But when you make use of a security protocol like this, your information will become unreadable to every go-between computer. Only the server that's serving as the final destination will be able to read it. SSL Provides Authentication - This simply means that you can rest assured your information will be available to no other server except the right one. The thing here is that your users can send their information from different parts of the world, and any computer can act as your server provider, stealing and collecting data from other users. So in order to avoid this, you need to ensure that you make use of public and private key infrastructures while getting an SSL certificate from a trusted and competent provider. Before getting SSL validations, companies pass through several identity checks. EV SSL certificates require a tough validation process. SSL Is Trustworthy - SSL certified applications have visual cues indicating that the connection is secure. It provides your clients with the inspiration to trust you before getting to know what you are offering them. Consider it to be a competitive edge for your software and a powerful way of making a good first impression. The presence of "HTTPS" on the browser bar simply means that the application is secure. Besides all the aforementioned security reasons, there are cases where SSL is simply a necessity. If your application collects credit card information, you are required to have an SSL certification as mandated by the Payment Card Industry. If your application has a login, sign up, or send query section that requires the sharing of private information, you need to make use of Extended Validation SSL certificates so as to secure your data transmission process. In a nutshell, if you want to appear more authoritative and deliver secure service through your VoIP software, we will recommend that you become SSL certified. However, it’s only a part of the story. You should have a reliable server hosting provider backing your VoIP software. IP2Voice is nothing but the best VoIP server hosting provider to provide you with what you are looking for.
