README

OPC UA .NET Standard — Security.Certificates

OPCFoundation.NetStandard.Opc.Ua.Security.Certificates is the certificate handling library that backs every OPC UA application certificate lifecycle: X.509 generation (CertificateBuilder), certificate stores (Directory / X509Store), CRL handling, certificate chain validation, certificate-signing-request issuance, and the high-level CertificateManager / ICertificateProvider / ICertificateValidator APIs.

Overview

Reference this package directly when you need to:

  • generate, rotate, or push application instance certificates outside the standard ApplicationInstance flow,
  • consume the CertificateManager provider model from a non-server / non-client process (e.g. an out-of-band PKI tool),
  • implement a custom ICertificateStoreType.

The package is referenced transitively from Opc.Ua.Core so server and client consumers get it for free.

Target frameworks

net472, net48, netstandard2.1, net8.0, net9.0, net10.0.

Additional documentation

See the main repository README and the Certificate Manager guide for the full provider model, certificate-store layout, and rotation flow.
