Note that the incorrect statement is: "Registration is the process where end users create an account with the RA and become authorized to request certificates." (Option B)
Imagine that you want a digital certificate, like a virtual ID for online safety. Here's the breakdown of how to do it:
1. Certificate Authorities (CAs) make sure certificates are real and know who's getting them.
2. Registration is where users sign up with a Registration Authority (RA) to ask for certificates.
3. CAs can let RAs handle sign-ups for them.
4. When you want a certificate, you fill out a Certificate Signing Request (CSR) – it's like a form saying, "Hey, I need a certificate!"
Now, all this ensures your online identity is safe and legit. But, remember, you don't want someone faking your digital ID!
