AES256_SHA256_RSAPSS security setting

Postby dotnet_developer034 » 10 Feb 2020, 09:26


I am developing a OPC UA client using the .NET SDK. I want my client to be able to connect to a server using any of the supported security settings, and all of them seem to work fine except for the AES256_SHA256_RSAPSS Sign and AES256_SHA256_RSAPSS Sign&Encrypt settings.

When I try to connect to the endpoint using this setting, I get the following error:
"[BadSecurityPolicyRejected] Error during EndConnect.|StatusException|Provider does not support the specified policy."

In the beginning I thought that it was my server which did not support this setting. But when I connect to the server using the UA Expert with this setting, it works just fine.

Any ideas what I am doing wrong?
