HTTPS Everywhere is a free Firefox, Chrome, and Opera add-on that encrypts all of your communications with major online websites, so that your surfing is completely safe. Essentially, this means that the website you are visiting has to be able to read your data without sniffing on any of it, or getting it in other ways. In other words, this software makes sure that your browsing is encrypted whenever you visit a website.
This software works to make your computer and every program on your computer "talk" via the Hypertext Transfer Protocol instead of the plain old HTTP. If you are familiar with HTTP, then you will know that it is a common protocol that is used by many websites to communicate information back and forth to their users. However, the problem with HTTP is that it was never designed to be a secure protocol, and so many websites, both those made for personal users and those meant to be used by business organizations, are not properly using it, leaving their users vulnerable to attack from both sides. For this reason, there is an urgent need to secure our data transfers - and the best way to do it is to download application security software which includes an HTTPS Everywhere add-on.
When it comes to downloading this software, you should make sure you have the correct browser installed on your computer and that you have read the directions carefully before you begin. There is no free version ofHTTPS Everywhere, because it is a licensed piece of software which must be purchased in order to use it. You can however download the free "practice" version and play around with it in order to see whether it is compatible with your system before purchasing the full version. This will also help you understand how the add-on works.
