Installing an SSL certificate can be a pain for the developer. You're not only tasked with getting the right type of certificate, the challenges come when you have to issue it, install it and then configure your Web server properly and migrate your entire website to HTTPS.

You can ease this burden and have an expert handle the SSL certificate installation. But if you're feeling challenged and want to try out the installation and configuration yourself, we're here to help.

CMLABS SSL Checker Tool

The SSL Checker tool from CMLABS can verify to check if the SSL certificate on your web server is installed properly and is trusted. SSL Checker will display the Common Name, server type, issuer, validity, certificate chain, along with additional certificate details.

By simply entering your host name or server IP address in the box below and clicking "Check", you can immediately view the details associated with your SSL certificate.

Importance of an SSL Certificate on Your Website

It is one of the important things for a website to have an SSL certificate. By having a certificate, the website is guaranteed to be safe from hackers and thieves who want to steal important website data.

Google will label unsafe websites without a certificate and may be subject to penalties. Users also need to be vigilant when entering personal data on websites without a padlock icon in the website address section.

The lock icon is one of the easiest markers to refer to whether a website is certified or not. To be more confident, you can search the SSL Certificate for the free tools offered online, one of which is the CMLABS SSL Checker App.

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

  • Useful As An Affirmation Of Website Identity

    Website data theft or cybercrime attacking data on websites is a thread for users. They will doubt whether the data they enter on the website is safe or not.

    The use of SSL Certificate on the website can provide authentication on the website to present a good reputation for the user. In this way, we can minimize users' concerns about the personal data they enter on the website.

  • Maximizing the ranking of the website on the SERP

    Google has set up websites with SSL Certificates to be preferred in search engine rankings. Since this provision, most websites have started switching from HTTP to HTTPS. According to SEO experts, many don't know that HTTPS has a big role in website ranking on search engines.

    Google can penalize websites without certificates, it affects the ranking of websites in SERP. In addition to the potential to increase rankings on search engines, certified websites are considered to be far safer from various online crimes or cyber crimes that are increasingly happening.

  • Ensuring Website Data Security

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

    The data is at risk of being compromised if the website is not fitted with a certificate. The existence of an SSL Certificate will increase the user's trust with the data they enter on the website.

How SSL Certificates Work on Websites

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

As a description and encryption of the data transport mechanism, SSL operates using 2 simple methods. The basic methods are:

  • Public Key

    Public key cryptography, also known as asymmetric cryptographic key, is a method that encrypts and describes data using two paired keys. In the asymmetric cryptography method, data that has been sent using the private key will only be opened using the public key, so in this method the data security process requires two connected keys.

  • Private Key

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

Stages of SSL Certificate

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

Handshake Protocol

The Handshake Protocol stage often precedes the SSL work process. At 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 the data. The Handshake Protocol is also the stage where the client will enable the first connection to the server by accessing the website and also making an SSL connection request.

Recording Protocol

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

Warning Protocol

SSL can filter or filter data that has been submitted by the client at this point. This protocol will select data from clients that are considered suspicious or do not meet standards. If an error occurs during the data transmission process, the server will automatically send an error warning message. Warnings issued by servers are usually divided into 3 types, namely warning signs, critical alerts, and finally fatal alerts.

Website SSL Certificate Type

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

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

1. SSL certificate in accordance with the validation process

Choosing a certificate should be in line with the needs of the website. Determine the purpose or goals of the website before deciding on a type of certificate. This is necessary because SSL is very influential on the authentication and encryption process of a website. The description of the kinds of certificates according to the validation process is as follows:

  • Extended Validation (EV)

    Extended Validation is the type of SSL certificate with the highest level of encryption. For websites with sensitive data transmission activities that need more legitimacy, such as online payments that require a lot of confidential user data, the use of Extended Validation is suggested.

    The feature provided by Extended Validation is a green address bar along with the company name, which makes the website look classier. However, if a website wishes to have an Extended Validation Certificate, there are some special conditions.

  • Organizational Validation (OV)

    Organization Validation is an SSL certificate with an encryption level that is moderate. This type of certificate is perfect for public websites such as government agency websites, as well as for websites that perform simple transmissions of sensitive data such as entering e-mails, usernames and passwords.

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

  • Domain Validation (DV)

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

    Obtaining this certificate is very easy, the validation process only requires a domain email address.

2. SSL Certificate According To The Number Of Domains

In choosing an 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 money. The following is an explanation of the types of SSL certificates based on the domain:

  • Multi-Domain SSL

    Is a type of certificate that many people are looking for because it is relatively cheap. The SSL multi-domain type provides configuration for multiple domains and sub-domains in a single host.

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

  • Wildcard SSL

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

    This certificate is considered more effective and also saves on administration costs because you do not need to buy certificates for one domain separately. If the website has a Wildcard certificate, the sub domains in it will also be protected by SSL automatically.

  • Single Domain SSL

    Only one domain or one subdomain can be covered by this certificate. In using Single Domain SSL, you must choose to provide protection to the primary domain or subdomain.

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