Certificate Security - KeyUsage

10 Feb 2022 18:04 #10608 by support

Yes, the KeyUsage is supported. That is, when generating application (client) instance certificates, QuickOPC generates certificates with proper key usage. The developer/user can also provide instance certificate of his own, in which case the KeyUsage values would depend on him.

Note: ECC is not yet supported.

Does the QuickOPC SDK for .NET support „ KeyUsage “ for certificates (Add-on to X.509 certificates defined in RFC 5280)?

According to the OPC UA standard this is required for RSA-Keys: OPC UA Online Reference .
