Using AES256 Encryption
If you are using AES256 encryption, install the JCE policy file on both the TDV server and the JDBC client.
To configure for AES256 encryption
1. Install the JCE crypto policy (unlimited version) in the TDV native JRE on the TDV server as follows:
a. Download the jce_policy-8.zip file from https://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html
b. Extract the zip file to your desktop.
This creates a folder called jce containing the following files:
README.txt
local_policy.jar
US_export_policy.jar
c. Copy the four files (NOT including the folder) into <TDV_Install_Dir>/jdk/conf/security on TDV server.
2. Restart the TDV server.
3. In the JDBC client, unzip the 4 JCE Policy Files (from the jce_policy-8.zip) into the jdk/conf/security folder of the JVM you are using as the JDBC client.
