In cryptography and computer security, a root certificate is a public key certificate that identifies a root certificate authority (CA). [1] Root certificates are self-signed (and it is possible for a certificate to have multiple trust paths, say if the certificate was issued by a root that was cross-signed) and form the basis of an X.509 ...

[4] It is intended to be a downstream , complete binary-compatible release using the Red Hat Enterprise Linux (RHEL) operating system source code. [ 5 ]
Therefore, each CA (root or intermediate) is only responsible for tracking the revocation of certificates it alone has issued. Consider the scenario where a root CA issues certificates to three intermediate CAs: A, B, and C: The root CA has issued a total of three certificates. The newly created intermediate CAs then issue their own certificates:
The roles of root certificate, intermediate certificate and end-entity certificate as in the chain of trust. In computer security, a chain of trust is established by validating each component of hardware and software from the end entity up to the root certificate. It is intended to ensure that only trusted software and hardware can be used ...
The new ISRG Root X2 is cross-signed with ISRG Root X1, Let's Encrypt's own root certificate.
