How to determine if a signing entitlement is real or hallucinated?

To determine if a signing entitlement is real or hallucinated, you should verify its origin and check for any inconsistencies. A real signing entitlement is typically issued by a trusted authority and contains specific details about the entity it's issued to. You can validate the entitlement by checking its digital signature against the issuer's public key. Additionally, be cautious of entitlements that seem suspicious or contain vague information.
