Which statement best describes a Self-Signed ID?

• A. It is a method to prove identity with a certificate issued by a trusted CA.
• B. It is essentially "vouching" for yourself.
• C. It requires a government-issued ID.
• D. It guarantees universal trust.

Answer: (B)

A Self-Signed ID is built on trust that comes from the entity itself rather than from an outside authority. In digital certificates, trust normally comes from a Certificate Authority that verifies identity and signs the certificate. When a certificate is self-signed, the entity signs it with its own private key, so the certificate is essentially vouching for itself. Because there’s no independent verification, other systems don’t automatically trust it unless you explicitly install and trust that certificate (or its root) in their trust store. It doesn’t require government-issued ID, since there’s no identity verification step. And it doesn’t guarantee universal trust, since many users and systems will treat it as untrusted unless you add it to a trusted store.
