Data Encryption Issue with Qlik Sense

[Rehan]

We are using QLik Sense April 2020 Patch 3. We have bunch of Oracle connections from the Qlik Sense Server. When our DBA ran the report in  Oracle he is seeing that the Oracle connections from Qlik Sense server are showing as unencypted. We have already updated the  sqlnet.ora file with the Encrypted connection string. 

How can I fix this issue so the connection wont show "unencrypted"

[Rehan]

Upon furtrher investigation seems like all the Oracle connections using the ODBC connection are showing up as Encrypted. The only Connection  which is showing up as unencrypted is the UDC connection my Connection string for the UDC connector is as below:  Am I missing something here that is causing the Unencrypted connection.

Visisble Connection STring       Driver ={Oracle in OraClient12Home1};dbq=MyDatabase;

Encrypted Connection String   uid=USer1;PWD=mypASSWORD.
