Manage CRLs

The NPKD Service provides CRLs to Inspection Systems that can used to check the revocation status of a Document Signer certificate. These CRLs can be imported to NPKD Service either manually by an operator or downloaded from the ICAO PKD. This module provides different options to manage all these CRLs.
