At TRUSTZONE we sell SSL certificates – but what does that even mean?

SSL or ‘Secure Sockets Layer’ is a protocol used by web browsers and servers when exchanging sensitive information such as passwords and credit card numbers. Huge quantities of information like this is sent back and forth across the Internet every second of every day, and it is therefore extremely important that the channels transporting the information from A to B are private.

To understand the difference between a private and a not-private online communication channel it helps to think about the difference between sending someone a postcard and sending them an old-fashioned letter in a closed envelope. With the postcard, the mail carrier is free to read the content if he or she wishes to do so, but with the letter the envelope protects whatever is inside from prying eyes.

A SSL certificate works much like an envelope, making sure that only the intended recipient can see the information you are sending.


When talking about SSL certificates and HTTPS you are also talking about encryption and encryption keys – but what exactly is an encryption key?

An encryption key is information, like numbers in an algorithm or a series of bits, which enable you to encrypt and/or decrypt a text. In short, the encryption key is able to transform readable plain text into unreadable cipher text and back again.  

If you can use the same key to both encrypt and decrypt the text, then the encryption is symmetrical. If on the other hand, you need one key to encrypt the text and another to decrypt it, then the encryption is asymmetrical.

SSL certificates use asymmetrical encryption, which is much harder to decode for an outsider, than symmetrical encryption is. By using both a ‘public key’, for encrypting text and verifying signatures, and a ‘private key’, for decrypting text and signing, you make sure that even if a hacker does get hold of one of the keys, it is useless without the other. On top of that, a ‘private key’ is notoriously difficult to decipher, even if you have access to its ‘public’ counterpart.

Therefore, when you use the two-key system to encrypt any type of sensitive information, you are taking an important extra step in ensuring the privacy of both yourself and your customers. TRUSTZONE only use asymmetrical encryption and on top of that, we have the best-supported 2048 root available.


If you have a website and you and your customers exchange sensitive information, then the answer is yes. Not having a SSL certificate can make your customers feel uncertain as to the safety of their personal data and that can ultimately lead them to choose another competing business who do offer this kind of security.

Furthermore, using SSL certificates protects you as a business owner from potential legal consequences or monetary loss if your customer’s privacy has been compromised. 

An SSL certificate ensures that the owner of a web site is actually who they say they are. This is possible due to different validation processes where a third party, like TRUSTZONE, authenticate the identity of the web site and its owner.

It is TRUSTZONEs mission to deliver fast and simple online-security and with our SSL certificates, both you and your customers can feel safe while sending information across the Internet.

Now you know more about what SSL is.
