Installing unlimited strength encryption Java libraries

Note: Oracle recommends using WebLogic 12.1.3 and Java 1.8. If you are upgrading from Empirica Signal 8.0 and you have decided to not use WebLogic 12.1.3 with Java 1.8, skip this section.

You install the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files to extend the security features in Java.

Perform these steps using the non-privileged user account on the application server.

Navigate to the jre/lib/security directory within your Java installation. For example:
$ cd /usr/java/jdk1.8.x_xx/jre/lib/security
Create a backup copy of the following files in another directory:
- local_policy.jar
- US_export_policy.jar
Download the jce_policy-8.zip file:
1. In an Internet browser, navigate to the Java SE Downloads website. For example:
  http://www.oracle.com/technetwork/java/javase/downloads/index.html
2. In the Additional Resources table, locate the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files for JDK/JRE 8 entry.
3. Click Download for the entry.
  The Download page appears.
4. Select Accept License Agreement.
  A confirmation message appears.
5. Download the jce_policy-8.zip file to a temporary directory.
Navigate to the directory that contains the jce_policy-8.zip file.
Unpack the jce_policy-8.zip file. For example:
$ unzip jce_policy-8.zip

The UnlimitedJCEPolicyJDK8 subdirectory is created. The subdirectory contains the following files:
- README.txt
- local_policy.jar
- US_export_policy.jar
Navigate to the UnlimitedJCEPolicyJDK8 subdirectory.
Copy the local_policy.jar and US_export_policy.jar files to the jre/lib/security directory within your Java installation. For example:
$ cp -f *.jar /usr/java/jdk1.8.x_xx/jre/lib/security/
Verify that the file permissions on the local_policy.jar and US_export_policy.jar files are set to rw-r--r-- (644).
