NTE_PROV_TYPE_NO_MATCH

NTE_PROV_TYPE_NO_MATCH means that the provider type supplied by the caller does not match the type registered for the selected provider. The provider name and numeric type describe incompatible CryptoAPI configurations.

How to fix the configuration

  • Check the provider name and provider type as one pair; changing only one side can preserve the mismatch.
  • Use the provider's documented type and supported algorithms rather than copying values from another CSP.
  • Add diagnostics that report both values so the mismatch can be reproduced on the affected machine.
