The Beheerorganisatie BSNk provides the Sleutelverstrekkingslijst containing the OIN's of all Service Providers (Dienstverlener) for whom DV-key material has been provided to their Broker (Toegangsdienst). The Sleutelverstrekkingslijst is mainly for transparency reasons (like Certificate Transparency, IETF RFC6962). The Beheerorganisatie BSNk publishes the Sleutelverstrekkingslijst in a fixed location. The file is available in XML format. Further information about the Key Provisioning list format can be found in the BSNk documentation (Contact Logius for more information).
