SSL explained

What Is SSL Certificate?

SSL (Secure Sockets Layer) is the cryptographic protocol which is liable for providing the communication security over the web. The segments of network connections are encrypted above the Transport Layer by SSL with the use of asymmetric cryptography.

Various versions of SSL certificates are being used widely in numerous applications like web browsing, E-mail, Internet Faxing, IM (Instant Messaging) and VoIP (Voice over IP).

SSL Certificate is like a small data file which connects a cryptographic key to a company’s details in a digital way. Upon its installation on the web server, the padlock and https get activated making the secured connection from the web server to the web browser. The SSL certificates are normally used for securing the credit card transactions, transferring of data, generating logins and for securing the social media websites. SSL Certificates bind together:
Protocol
TLS 1.2 / 1.3
Encryption
Up to 256-bit
Key length
2048-bit RSA
Validation levels
DV, OV, EV
Free with hosting
Yes, auto-renewing
SSL at a glance

What an SSL Certificate Does for Your Site

Encryption is the obvious part. The rest is about trust, ranking and whether browsers let visitors through at all.

Encrypts data in transit

Credit card transactions, transferring of data, logins and social media traffic are scrambled between the browser and your server, so nobody on the network in between can read them.

Binds your identity to the key

The certificate binds together the domain, server or host name with the identification of the organization — company name and location — to the level the authority has verified.

Helps your search ranking

HTTPS has been a confirmed Google ranking signal for many years. Sites still on http are at a measurable disadvantage.

Removes the “Not secure” warning

Visitors look for the padlock icon and the “https” prefix before submitting personal details. Without a certificate they are more likely to leave without buying or signing up.

Required to take payments

PCI DSS requires encryption for card data, and every payment gateway refuses to operate on an unencrypted checkout.

Unlocks modern protocols

HTTP/2 and HTTP/3 only run over TLS. Enabling SSL is what lets your site use the faster transport browsers already support.
