SSL, which stands for Secure Sockets Layer, is a standard security technology for establishing an encrypted link between a web server and a browser. This link ensures that all data passed between the web server and browsers remain private and integral. SSL is widely used to secure credit card transactions, data transfer, and logins, and more recently has become the standard for securing browsing of social media sites. # What is SSL? SSL, which stands for Secure Sockets Layer, is a standard security protocol for establishing encrypted links between a web server and a browser in an online communication. It's designed to ensure that data transmitted between the web server and browser remains secure and confidential. SSL encrypts the information exchanged, making it extremely difficult for unauthorized parties to intercept or decipher the data. # The primary goals of SSL are: Encryption: SSL encrypts the data transmitted between the user's browser and the web server, preventing eavesdropping and data theft by malicious actors. Authentication: SSL provides authentication, ensuring that users are communicating with the intended website and not an impostor or intermediary. This helps prevent man-in-the-middle attacks. Data Integrity: SSL ensures that the data transmitted between the user and the server remains intact and hasn't been tampered with during transmission. SSL certificates, issued by trusted Certificate Authorities (CAs), play a crucial role in the SSL process. These certificates verify the identity of the website and establish trust between the website and the visitor's browser. When a website has an SSL certificate installed, the browser displays a padlock icon in the address bar, indicating a secure connection. Additionally, the website's URL begins with "https://" instead of "http://", where the "s" stands for secure. # Types of SSL There are several types of SSL certificates available, each offering different levels of security and validation. Here are the main types: Domain Validated (DV) SSL Certificates: These are the most basic type of SSL certificates. They only verify that the domain name matches the one in the certificate, providing encryption for the connection. DV certificates are typically the quickest and cheapest to obtain and are suitable for basic websites where trust is less of a concern. Organization Validated (OV) SSL Certificates: OV certificates provide a higher level of validation compared to DV certificates. In addition to verifying domain ownership, the CA also confirms the identity of the organization that owns the domain. This additional validation provides a higher level of trust for website visitors. OV certificates display the organization's name in the SSL certificate details. Extended Validation (EV) SSL Certificates: EV certificates offer the highest level of validation and trust. They undergo the most rigorous validation process, including verifying the legal existence, physical location, and operational status of the organization. Websites with EV certificates display the organization's name prominently in the browser's address bar, along with a green padlock icon. This visually distinguishes them as highly secure and trustworthy. Wildcard SSL Certificates: Wildcard SSL certificates allow secure communication for a single domain and an unlimited number of its subdomains. For example, a wildcard certificate issued for "*.example.com" would secure "www.example.com", "mail.example.com", "blog.example.com", etc. This is convenient for organizations with multiple subdomains as they can secure them all with a single certificate. Multi-Domain (SAN) SSL Certificates: Multi-Domain SSL certificates, also known as Subject Alternative Name (SAN) certificates, allow securing multiple domain names with a single certificate. They can secure up to a specific number of domains (e.g., 5, 10, 25) and their associated subdomains. This is useful for organizations with multiple websites or domains. Unified Communications (UC) SSL Certificates: UC certificates are specifically designed for Microsoft Exchange and Office Communications environments. They allow securing multiple domain names, host names, and server names associated with Microsoft Exchange Server, Office Communications Server, and other Microsoft collaboration platforms. Each type of SSL certificate serves different needs based on the level of validation required, the number of domains or subdomains to secure, and the desired level of trust and assurance for website visitors. # How to buy ssl from best ssl provider To buy an SSL certificate from the [best SSL certificate providers](https://mashupmind.com/best-ssl-certificate-providers/) for your needs, follow these general steps: Identify Your Requirements: Determine the type of SSL certificate you need based on your website's requirements.
