Digital certificates are verified through the use of another certificate, creating a chain of certificates that ends with the root certificate
The issuer of a certificate is called a certification authority (CA). The owner of the root certificate is the root certification authority.
A root certificate is a digital certificate at the top of a certificate chain, used to authenticate the identity of certification authorities (CAs) or intermediate certificates. It serves as the trust anchor for the entire chain of trust in digital certificates. Root certificates are embedded in operating systems, web browsers, and other applications to establish trust in secure online communication.
There an infinity of such numbers. One test for divisibility by 9 depends on the digital root. The digital root of any number is the sum of all its digits. If the digital root of a number (or the digital root of its digital root) is divisible by 9 then the original number is, and if the DR is not then the original number is not.
The digital root of 679 = 6+7+9 = 22 The digital root of 22 = 2+2 = 4

There are five root keys.
9 + 5 + 2 = 16, 1 + 6 = 7 so the digital root is 7
It is called the digital sum. If you keep doing it until you reach a single digit answer, it is called a digital root. The term digital root is sometimes also used for the digital sum. For example, 3042 gives the digital sum of 3+0+4+2 = 9 which is also its digital root. but 3047 gives the digital sum of 3+0+4+7 = 14 and the digital root is 1+4 = 5.
The root word for digital is digit.
Any number whose digital root is 9.To find the digital root of a number,add together all its digits.if the answer is bigger than 9, go back to step 1. Otherwisethe sum is the digital root.
Web certificates are derived from root certificates. So, for example, root certificates come from certificate authorities like Verisign and are built into web browsers. Web certificates are those that companies get from the certificate authorities and those will use the root certificate as part of the validation process.
