Cryptographic Services - Windows XP Service
Provides three management services: Catalog Database Service, which confirms the signatures of Windows files; Protected Root Service, which adds and removes Trusted Root Certification Authority certificates from your computer; and Key Service, which helps enroll your computer for certificates. If this service is stopped, these management services will not function properly. If this service is disabled, any services that explicitly depend on it will fail to start.
This service also exists in Windows 10, 11, 7, 8 and Vista.
