These certificates consist of root certificates, intermediate certificates, and leaf server certificates. Intermediate certificates are certificates that are designed to mitigate risk by creating a separator between the root certificates and SSL certificates. This is because issuing a certificate straight from the root would be too dangerous if it were to become compromised, as the root certificate has the most authority and needs to be protected.
As for Root CA certificates, these are certificates that are self-signed by their respective CA as they have the authority to do so. Every valid SSL certificate is under a Root CA certificate, as these are trusted parties like Comodo or Sectigo who have been established in the industry as security leaders. Shop Now. You can manually install the root certificate of a private CA into the Trusted Root Certification Authorities certificate store on a computer by using the CertMgr tool.
Note The driver signing verification policy that is used by the PnP manager requires that the root certificate of a private CA has been previously installed in the local machine version of the Root Certification Authorities certificate store.

A certificate chain is a list of certificates usually starting with an end-entity certificate followed by one or more CA certificates usually the last one being a self-signed certificate , with the following properties: The issuer of each certificate except the last one matches the subject of the next certificate in the list.
Each certificate except the last one is supposed to be signed by the secret key corresponding to the next certificate in the chain i. The last certificate in the list is a trust anchor : a certificate that you trust because it was delivered to you by some trustworthy procedure. A trust anchor is a CA certificate or more precisely, the public verification key of a CA used by a relying party as the starting point for path validation.
There are three parts to the chain of trust : Root Certificate. A root certificate is a digital certificate that belongs to the issuing Certificate Authority. Intermediate Certificate. Intermediate certificates branch off root certificates like branches of trees.
They act as middle-men between the protected root certificates and the server certificates issued out to the public. There will always be at least one intermediate certificate in a chain, but there can be more than one. Server Certificate. The server certificate is the one issued to the specific domain the user is needing coverage for.

Moreover, without the intermediate certificates, you would have no way of validating the certificate signatures, since each certificate is used to sign the the next certificate in the chain, starting from the root cert.
Having said that however, often times chains may be only two are three nodes long, and signing certificates are often available from CA's web servers. I clicked the lock icon in Chrome, and "Certificate information" Notice that the Issued by: field lists the display name of the issuing CA.
This name is not necessarily unique, so for more details, go to the Details tab and find the Issuer field: This lists the full Distinguished Name DN of the issuing CA, which will be unique within their organization, but could be spoofed I guess.
To check the actual certificates Here you can open up each of the certs in the chain and inspect them. Mike Ounsworth Mike Ounsworth
