A bunch of SSL security tools which you can use directly. These tools are free to use.

What is SSL?

SSL literally stands for Secure Sockets Layer, which means that a secure layer is placed between a server and an internet browser, which protects the data.

SSL certificates use the https protocol of the browser (via port 443) which establishes the secure connection.

SSL Certificates

An SSL certificate is a file that provides better security of data between the server (of your website) and an internet browser.

Because SSL certificates attach a secure key to the connection of a website, data can be stored in live encryption, so that it can be entered securely without the intervention of external systems that want to intercept the data.

In this way, login and payment details such as passwords, credit card numbers and personal data can be used safely on websites that are secured with an SSL certificate.

Requesting an SSL certificate must be done by the owner of the website at a certificate authority. The web hosting provider can then install the SSL certificate in the correct package on the server.
