THPDFCSCSignatureProvider.RefreshCredentialInfo Method
function RefreshCredentialInfo(
const OperationIdentifier: AnsiString= ''):
THPDFSignatureProviderStatus;Fetches and validates the CSC credentials/info document for the configured credential without carrying out any signing
The refreshed metadata, including key size, algorithm, authorisation requirement, SCAL value, multisign limit and the complete certificate chain, is cached on the provider and exposed through the CredentialInfo property
An optional OperationIdentifier labels the refresh for cancellation and transport correlation; when omitted, the call is not tied to any signing operation
Calling this before signing avoids a credentials/info round trip inside the first signing operation and lets applications fail quickly on misconfigured credentials
