Answer 1

If you are using Linux distribution with apt and have added webupd8 PPA, you can simply run the command

apt-get install oracle-java8-unlimited-jce-policy

---

Other updates:

1. The Unlimited Strength Jurisdiction Policy Files are included with Java 9 and used by default
2. Starting with Java 8 Update 161, Java 8 defaults to the Unlimited Strength Jurisdiction Policy.

3. Starting with Java 8 Update 151, the Unlimited Strength Jurisdiction Policy is included with Java 8 but not used by default. To enable it, you need to edit the java.security file in /jre/lib/security (for JDK) or /lib/security (for JRE). Uncomment (or include) the line

   crypto.policy=unlimited

   Make sure you edit the file using an editor run as administrator. The policy change only takes effect after restarting the JVM

Before Java 8 Update 151 rest of the answers hold valid. Download JCE Unlimited Strength Jurisdiction Policy Files and replace.
