Online transactions have become an integral part of our lives. People share sensitive personal information, such as their credit card, login credentials, and so on. online. The user, while sharing such details on the net, should not feel threatened that his details will be misused. For this reason, domain security has become a necessity. SSL is one of the methods to ensure domain security.
SSL or Safe Security Layer is a security technology that establishes an encrypted link between a web server and a browser. This ensures the security of all data between web servers and browsers.
Browsers can interact with secure Web servers only through SSL. For this, the browser and the server both require a secure security layer certificate. This certificate provides a secure connection between the two.
Steps to obtain an SSL certificate
The user who needs the certificate creates a Certificate Signing Request (CSR) on his server and sends it to the Certificate Authority (CA). The CA must be a trusted organization like DigiCert, etc.
Once the request is sent, public and private keys are generated on the server.
The CSR data file sent contains the public key.
CA uses CSR data to create a data structure corresponding to the private key. However, the certification authority can not see the actual private key.
An SSL certificate is received by the user.
The user can then install the certificate on his server.
An intermediate certificate is also installed to authenticate the credibility of this certificate.
Safe Security Layer certificate types
Domain validated
This is a private certificate that is ideally used when secure communication is established between the client and the website. It is directly related to the domain, so that customers know that they are using the right website.
Validated company
In this type of certification, additional documents are required to certify the company's identity. A certificate validated by the company generates more trust in the user.
Extended validation
It provides security against fraud by performing additional checks and validations. The address bar & # 39; https & # 39; is exclusive to this certificate. & # 39; s & # 39; means secure.
Wild Card
This facilitates encryption on an unlimited number of domains using a single certificate. However, all subdomains must have the same second-level domain name.
Multi domain
This type of certificate allows a maximum of 210 domains. It also allows to mix domain names.
The user can select any of these certificates according to his needs. Various SSL certificates indicate security in different ways. When a user visits a website on which an SSL certificate is installed, a padlock or green bar appears on the browser to indicate security.
