THPDFCSCSignatureProvider.RefreshCredentialInfo Method
function RefreshCredentialInfo(
const OperationIdentifier: AnsiString= ''):
THPDFSignatureProviderStatus;Fetches and validates the CSC credentials/info document for the configured credential without signing anything
The refreshed metadata, including key size, algorithm, authorization 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 associated with a signing operation
Calling this before signing avoids a credentials/info round trip inside the first signing operation and lets applications fail fast on misconfigured credentials
