Cryptographic Services (CryptSvc) Defaults in Windows 8
Provides three management services: Catalog Database Service, which confirms the signatures of Windows files and allows new programs to be installed; Protected Root Service, which adds and removes Trusted Root Certification Authority certificates from your computer; and Automatic Root Certificate Update Service, which retrieves root certificates from Windows Update and enable scenarios such as SSL. 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 8 it is starting automatically during the operating system startup. Then the Cryptographic Services runs as NT Authority\NetworkService in a process of svchost.exe, sharing it with other services. If Cryptographic Services fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the CryptSvc service hasn't been started.
Dependencies
Cryptographic Services can't start, if the Remote Procedure Call (RPC) service is disabled or not available.
If Cryptographic Services is disabled, the Application Identity service will not be started and initialized.
