What is a Digital ID?

May 25, 2018 in Windows and Code Signing

A Digital ID also known as a digital certificate is a form of electronic credentials for the Internet.
A Digital ID is issued by a trusted third party to establish the identity of the ID holder.
The third party who issues certificates is known as a Certification Authority (CA).
Digital ID technology is based on the theory of public key cryptography.
In public key cryptography systems, every entity has two complementary keys, a public key and
private key, which function only when they are held together.
The purpose of a Digital ID is to reliably link a public/private key pair with its owner.
When a CA issues Digital IDs, it verifies that the owner is not claiming a false identity.
