What is an Intermediate certificate?
An intermediate certificate is so called a chain certificate that plays a vital role in chaining the server certificate and the root certificate. It may happen that when a website owner gets SSL from a certificate authority, the browser or operating system may not explicitly know the CA. Therefore, to enable trust in the browser, there should be a duly signed intermediate certificate. With intermediate certificate, the browser will not show warnings while connecting to your website. It is an additional level of surety and security. The SSL certificate holder has to install an intermediate certificate along with the purchased SSL certificate to build a trust chain.

What is a Root CA certificate?
The Root CA certificate is an integral part of public key cryptography that is used by browsers to authenticate different types of encryption. The root certificate is placed on the end user’s machine. When a user tries to connect to the website via HTTPS, Root certificate ensures that a user is connected to the right identity but not a fake one. A root certificate is the top most certificate, of which private key is used to sign the other certificates. All certificates listed under the root certificate automatically get the trust from the root certificate. Root certificate works on ITU-T X.509 standard and can be an unsigned or self-signed certificate. Currently, root certificate carries robust 2048-bit encryption strength.
