The convenience of using various services of Internet providers is undoubted. However, the experience should be safe because there are lots of threats out there. Users often need to provide their sensitive data, such as credit card details. When the information travels over the Internet unencrypted and unprotected, it can be stolen and used. So, how can important details stay protected? An SSL certificate is used for this purpose.
It is not a single protocol available for users, so it is essential to know how to pick the right one. Site owners can purchase cheap SSL certificates that come with great quality if they know where to search. Learn the comprehensive information on this method of protection by keeping reading this review.
What Is SSL?
This abbreviation means Secure Sockets Layer. In essence, it is a protocol used for information coding or encrypting to deliver the data to the final destination in a safe manner. The initial text cannot be read by cyber thieves even if it is stolen because it is converted into an unreadable set of characters.
While today a more advanced protocol called Transport Layer Security or TLS is used, this encryption technology is still commonly referred to as SSL.
Not every site owner needs to get SSL certificate. If it is a blog, portfolio, or another type of site that does not require users to enter any sensitive info, then it can perfectly operate without this type of protection. However, all sites related to e-commerce should have cheap SSL certificate installed.
Sites with proper certification are easy to indicate. The way of indication depends on the browser. For example, if it is Chrome, the users will see the padlock icon next to the site address.
How Do SSL Certificates Work?
It may be useful to have a clear idea of how such a protocol can ensure data protection. There are two ways to protect info using cryptography:
- Asymmetric;
- Symmetric.
The first one utilizes two keys for encrypting and decrypting. The public key is shared with those interested in communication. The second key comes with the private status. Both keys are created using a mathematical algorithm.
When it comes to the use of asymmetric cryptography, the information is encrypted with one key and decrypted with the other one. The core difference of symmetric cryptography is that a single key is used.
A Step-by-step Algorithm of SSL Work
So, this is how SSL certificate get the date transferred safely and securely over the Internet:
- The sender sends a message which contains some essential info such as the version of SSL, specific data, and other information;
- The server then also sends a message. It comes with relevant information as well, such as the version of SSL, specific data, and others;
- The sender verifies the SSL certificate of the other party and authenticates the server if everything is fine. In case the authentication is not passed, the SSL connection will not be established;
- In case of successful verification, a session key is created and sent to the server. It is sent in the encrypted form;
- After obtaining the key, it is decrypted by the server with its private key and the confirmation to the sender is sent.
Types of SSL certificates
There are three main types of such certificates:
- Validation of different criteria (extended);
- The validation of organization;
- The validation of domain.
Extended Validation (EV) Certificates
SSL EV certificates are most commonly used by site owners. They allow for multiple verification procedures including verification of domain. In case of fraud, it will be easy to trace the thieves. Using this type of protocol, the CA checks the sender’s rights to utilize a certain domain name. Such certificates come for businesses of all possible types. They can also be used by government organizations.
Organization validated (OV) certificates
When it comes to this type of validation, not only the domain is checked, but also the organization. This allows making sure that the website used by users is legitimate. Along with other essential data, the name of the organization is displayed in the relevant field of the certificate.
Domain validated (DV) certificates
No organization will be shown for users when this type of protocol is used because it does not simply exist. There will only be a padlock icon in the address bar. The main responsibility of this certificate is to validate the ownership of the domain. This type of certificate is suitable for those who wish to ensure anonymity without displaying any information about them such as name, location, etc.
Some of the benefits of DV SSL Certificates include high speed of issuance. Such a protocol can be obtained nearly instantly without having to submit lots of documents. Also, it is a cheap alternative to other types of certificates.
How to Choose the Right Certificate?
Various factors should be considered to pick an SSL certificate for website. These tips will ensure the right choice depending on the individual situation:
Validation level
The information on different levels of validation is provided in the article above. It explains the core differences between the levels, allowing site owners to pick the right one.
The Number of Domains
If a site owner has several sites, they should think of getting a proper package allowing the use of several certificates on multiple domains. A special offer is available for those who also need to protect subdomains. In essence, those are separate pages of the website, for example, the login section.
Warranty Amount
It is offered as compensation in case of successful data breaches. The amount depends on the type of protocol. Normally, certificates that come with a greater level of validation offer a high amount of payback.
Price
SSL certificate price also belongs to essential factors to consider. Different factors can influence the price. Some of them are a type of SSL, validation timeframes, brand, and others. Usually, it is possible to benefit from a lower price if the certificate is purchased for several years.
Issuance Time
The amount of time needed to issue such a certificate depends on a range of factors. If a user needs to obtain a protocol instantly, then domain validation would be the right option.
If the choice is OV SSL, then it will take up to three days to get it. As for the EV SSL, site owners can expect to wait for up to four days to receive it. However, some delays may also take place, for example, if additional data is required by the CA.
Additional Security Features
There may also be additional elements included for an enhanced level of protection. A site owner may check whether they are included and what their role is before purchasing a certificate.
Customer Support
After you add SSL to website URL, you may comfortably do other things. However, different unpleasant situations may happen to your certificate, and you need to know how to act in such cases. Before purchasing the certificate from a certain company, make sure that it provides around-the-clock support.
