Cryptographic Services (CryptSvc) Defaults in Windows XP
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.

Default Behavior
Cryptographic Services is a Win32 service. In Windows XP it is starting automatically along with the operating system. Then the Cryptographic Services is running as LocalSystem in a shared process of svchost.exe. Other services and drivers are allowed to run in the same process. If the Cryptographic Services fails to start, the technical information about the error is added to the Event Log. Windows XP startup should proceed, but a message box should be displayed informing the user that the CryptSvc service has failed to start.
Dependencies
Cryptographic Services depends on the Remote Procedure Call (RPC) service.
