The Importance of SSL Certificate on Your Website

Having an SSL certificate is one of the important things for a website. By having a certificate, the website is guaranteed safe from hackers and thieves wanting to steal important website data.

Google will give the label "not secure" on websites without a certificate and can be subject to penalties. Users also need to be vigilant when entering personal data on websites with no lock icon in the address section of the website.

The lock icon is one of the easiest markers to reference whether the website is certified or not. If you want to be more sure, you can check the SSL Certificate on the free tools that have been provided online, one of which is the SSL Checker Tool from CMLABS.

The use of SSL on a website has several advantages in improving the quality of the website. Here are some important points for using an SSL Certificate on a website :

  1. Useful As An Affirmation Of Website Identity

    Website data theft or cyber-crimes who attack data on websites are the thread for users. They would doubt whether the data they have entered on the website is secure or not.

    The use of an SSL Certificate on a website can provide authentication on a website to bring up a good reputation for users. This way, we can minimize user concerns about the personal data they enter on the website.

  2. Maximizing website ranking on SERP

    Google has set websites with SSL Certificate to be preferred in search engine ranking. Since this provision, the majority of websites have started to switch from HTTP to HTTPS. According to SEO experts, many don't know that HTTPS has a big role in the ranking of websites on search engines.

    Google can penalize websites with no certificate, it affects the website's ranking on the SERP. In addition to the potential to increase rankings on search engines, certified websites are considered to be much safer from various online crime or cyber crimes that are increasingly happening.

  3. Ensuring Website Data Security

    The use of an SSL Certificate is very important in ensuring the level of data security on the website. If a website uses an email, password, or other important information for login, it is necessary to use SSL on that website.

    If the website is not equipped with a certificate, the data is at risk of being hacked. The existence of an SSL Certificate would increase the users’ confidence with the data they entered on a website.

How SSL Certificates Work on Websites

SSL works by encrypting data through a very fast process with a count per millisecond. SSL certificates work to secure the data exchange process between one server and another server and the data transfer process that occurs between the web server and client or web browser.

SSL works using 2 basic methods as description and encryption of the data transport process. The basic methods are :

  1. Public Key

    Public Key Cryptography or known as asymmetric cryptographic key is a method that performs encryption and data description using two paired keys. In the asymmetric cryptography method, data that has been sent using a private key will only be open using a public key, thusin this method the data security process requires two connected keys.

  2. Private Key

    Private Key Cryptography or also known as a symmetric cryptographic key is an SSL working method that encrypts data with just one private key. If you want to decrypt data, both the sender and the recipient must have the unlock key.

In broad terms perspective, SSL Certificates work using 3 important steps. The stages of working with an SSL Certificate include :

  1. Handshake Protocol

    The SSL work process is always preceded by the Handshake Protocol stage. In this stage, the encryption algorithm negotiation process and the server authentication process occur. The Handshake protocol stage will usually use a private key or symmetric cryptography to encrypt data. The Handshake Protocol is also the stage where the client will fire the first connection to the server by accessing the website and also making an SSL connection request.

  2. Record Protocol

    Record Protocol is a working stage where the data encryption process takes place. Record Protocol is also known as a record protocol because this protocol will store all types, versions and lengths of data that has been transmitted. In addition, the Record Protocol also provides digital signatures and message digest (MD) records relating to data security. The validation process between the client and server occurs at this stage.

  3. Alert Protocol

    At this stage SSL will filter or filter data that has been sent by the client. This protocol will select data from clients that are considered suspicious or does not fulfill the standards. If an error occurs during the data transmission process, the server will automatically send an error warning message. The alerts issued by the server are usually divided into 3 types, they are warning signs, critical, and finally fatal warning signs.

Type of Website SSL Certificate

Selection of an SSL Certificate requires careful consideration based on the results of the analysis related to the website needs and budget. Take into account the type of SSL certificate to choose before purchasing it.

We recommend that you choose an SSL certificate according to the core needs of each web. Certificates are divided into two types, certificates based on the validation process and certificates based on the number of domains.

  1. SSL certificate according to the validation process

    Choosing a certificate must be in line with the needs of the website. Decide the purpose or goal of the website before deciding on one type of certificate. This is necessary because SSL is very influential on the authentication and encryption process of the website. The following is an explanation of the types of certificates according to the validation process :

    1. Extended Validation (EV)

      Extended Validation is a type of SSL certificate with the highest level of encryption. The use of Extended Validation is recommended for websites with sensitive data transmission activities that require more credibility, such as online payments that require a lot of confidential user data.

      The feature presented by Extended Validation is a green address bar along with the company name, which makes the website look more classy. However, there are some special requirements if a website wants to have an Extended Validation Certificate.

    2. Organization Validation (OV)

      Organization Validation is an SSL certificate with a moderate level of encryption. This type of certificate is very suitable for public websites such as government agencies websites, also for websites that perform simple transmission of sensitive data such as inputting email, username and password.

      OV type certificates will also protect sensitive user data during the data transmission process.

    3. Domain Validation (DV)

      It is a basic SSL certificate with the lowest level of encryption. Domain Validation type certificates are recommended for blog or web owners that do not require sensitive data transmission processes because the level of security tends to be low.

      It is easy to get this certificate, the validation process only requires a domain email address.

  2. SSL certificate according to the number of domains

    In selecting the SSL Certificate, you need to consider the number of domains and subdomains to protect. By choosing the right certificate, you can save a lot of budget. The following is an explanation of the types of SSL certificates based on the domains :

    1. Multi-Domain SSL

      Is a type of certificate many people are looking for because it is relatively cheap. Multi-Domain SSL type will provide configuration of several different domains and subdomains in one hosting.

      One of the features of Multi-Domain SSL is the access to add, delete, and also change the Subject Alternative Name (SAN) according to the needs of the website.

    2. Wildcard SSL

      Wildcard SSL is a type of certificate that can protect one main domain and protect unlimited sub domains. Wildcard SSL certificates are very suitable for websites with many sub domains.

      This certificate is considered to be more effective and also saves administrative costs because you don’t have to purchase certificates for a single domain separately. If a website has a Wildcard certificate, the sub domain in it will also be protected by SSL automatically.

    3. Single Domain SSL

      This certificate can only protect one domain or one subdomain. In using Single Domain SSL, you need to choose to provide protection to the main domain or subdomain.

      As a simple example, if the cmlabs.co website uses a Single Domain certificate and chooses to protect the main domain, then the tools.cmlabs.co subdomain website will not be protected. Likewise, if you choose to protect the sub domain, the main domain cmlabs.co will not be protected
