rm adoptopenjdk-keyring.gpg* public

Update the security settings to allow strong encryption and decryption of files: set the crypto.policy to unlimited for the JRE used by PhixFlow.
- To do this, go to the JRE directory /lib/security/java.security file.

If you have installed a JDK rather than a JRE, you will find this directory under

JAVA_BASE_INSTALLATION/jre

E.g.

C:\Program Files\Eclipse Adoptium\jdk-8.0.312.7-hotspot\jre

The crypto.policy line is commented out.

# crypto.policy=unlimited

Delete the #" to uncomment the line:

crypto.policy=unlimited

You do not need to set the environment variable JAVA_HOME, but some operators find this useful for convenience. Note that some installation processes will set this for you. If you decide you wish to set this and it has not been set by your installation process, set it to the base installation directory of Java, e.g.

C:\Program Files\Eclipse Adoptium\jdk-8.0.312.7-hotspot

/usr/lib/jvm/adoptopenjdk-11-hotspot-amd64

We strongly recommend that you use the latest version of Java.

For versions before Java 1.8.0_151, you must install the JCE Unlimited Strength Jurisdiction Policy files.
