DB2 .Net Connector error : AESEncryptADONet

问题

I have a very simple .Net Core app trying to create and open a connection to a DB2 database (on AS/400). I have this error when I try to create the DBConnection object, with the message:

ERROR 58005 SQL0902 There are no context policies. Function: AESEncryptADONet.

There are no more details, unfortunately.

We meet the same error and solved it by setting Path of environment variables on Windows / Linux (LD_LIBRARY_PATH) / MacOS (DYLD_LIBRARY_PATH). For example:

Our environment:
- ASP.NET Core v3.1
- IBM .NET Core 3.1 / EntityFrameworkCore 3.1 in v11.5.4
- IIS 8.5
- Windows Server 2012 R2 (64 bits)

In web.config, we add the

<environmentVariable name="Path" value="C:\Users\Administrator\.nuget\packages\ibm.data.db2.core\3.1.0.200\buildTransitive\clidriver\bin" />

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location ... >
    <system.webServer>

      ...

      <aspNetCore ... >
        <environmentVariables>
          <environmentVariable name="Path" value="C:\Users\Administrator\.nuget\packages\ibm.data.db2.core\3.1.0.200\buildTransitive\clidriver\bin" />
        </environmentVariables>
      </aspNetCore>
    </system.webServer>
  </location>
</configuration>

Set folder permissions (Read & Execute, Read, and List Folder Contents) for Application Pool Identity Accounts (IIS AppPool\[App_Pool_Name])

Q: I am getting the following error:

An unexpected exception has occurred in Process: 244 Function: AESEncryptADONET (Encryption Info)

The .NET driver is unable to find the compatible GSKit. Set the Path(on Windows) or LD_LIBRARY_PATH(on Linux) to the <Package_Install_location>/<package-name>/<version>/build/clidriver/lib directory of your environment. Remember, this may affect other applications.
