SSL (Secure Sockets Laye) is a protocol for establishing an authenticated and encrypted connection between your computer and server. SSL makes the connection secure and also protect the sensitive data which is sent between the server and client.

SSL is a secure certificate that offers three-layer of protection Authenticity, Data Integrity, Encryption.
  1. Authenticity: server presenting the certificate is in possession of the private key that matches the public key in the certificate.
  2. Data Integrity: It guarantees that your data cannot be modified or corrupted during transfer without being detected.
  3. Encryption: This means that all data send between the browser (client) and website (server) is encrypted.
Look for the following indicators in your browser’s address bar to be sure that a website you are visiting is protected with a trusted SSL certificate

Steps to install the SSL certificate for a subdomain
Step 1. Point your subdomain to your server
