SSL Certificate

Definition

An SSL certificate, or Secure Sockets Layer certificate, is a cryptographic protocol that provides secure communication over a computer network. This digital certificate verifies the identity of a website and encrypts the information sent to the server using SSL technology. Encryption is the process of scrambling data into an undecipherable format that can only be returned to a readable format with the proper decryption key.

Usage and Context

An SSL certificate is used when a web page wants to accept sensitive data like credit card numbers, passwords etc. When an SSL certificate is used, the information becomes unreadable to everyone except for the server you are sending the information to. This protects it from hackers and identity thieves. In the context of SEO, Google has confirmed that HTTPS, which requires an SSL certificate, is a ranking signal. Sites that are SSL-secured may have a slight edge in terms of SEO over those that aren't.
