SSL certificate – why it makes your website more secure

Internet’s creation brought to the table a lot of possibilities but also a strong need for security. The development of all kinds of solutions for keeping businesses operating safely is a clear priority. In that environment, the SSL certificate plays an important role.

What is a SSL certificate?

SSL means secure socket layer. SSL certificate is a useful cryptographic protocol to protect the communication browsers-servers of websites. It helps browsers to verify servers’ identity, and it protects all data passing between them through encryption.

How does a SSL certificate work?

SSL certificate is a data file that holds the public key and identity of a website. The public key is half part of an encrypting mechanism that works with two keys, the public and a private one. This last is managed exclusively by the website owner to secure data that would be readable (decryptable) for others through the use of the public key.

The public key is a long numerical value for encrypting data. It is created and given by a specific and reliable authority. Its access remains public.

SSL certificate (data file) lives in the name server of a website, and it makes encryption possible. Every time a device communicates with a name server to request a website, this data file will be the reference to get the public key and verify the server’s identity.

SSL has a big advantage. When enabled, it is visible for users. For sure, you have seen during your daily surfing on Internet the padlock on your browser or the HTTPS before the domain name. Those signs mean you are visiting a secure website with a SSL certificate.
