Java Cryptography Extension requirement for connecting to Nutanix Cluster in PowerChute Network Shutdown
Issue:
In certain geographies, it is necessary to install the Java Cryptography Extension policy files to connect to a Nutanix Cluster that requires a 256-bit cipher.
Product:
PowerChute Network Shutdown v4.3
Environment:
All supported operating systems
Solution:
Due to the import control restrictions of some countries, the version of the Java Cryptography Extension (JCE) policy files that are bundles with the Java Runtime Environment 8 (JRE 8) allow ‘strong’ but limited cryptography to be used: they have in-built restrictions on available cryptographic strength. Depending on your geographical location (e.g. outside of the United States), to connect to a Nutanix Cluster that requires a 256-bit cipher, it may be necessary to first download and install the Unlimited Strength JavaTM Cryptography Extension (JCE) Policy Files available from the Oracle website.
NOTE: It is recommended to consult your export/import control counsel or legal counsel to determine the exact cryptographic strength required for your geographical jurisdiction.
NOTE: This issue is resolved in PowerChute Network Shutdown v4.4 which uses OpenJDK 14.

Steps to install the JCE policy files:
- Download and extract the Unlimited Strength Jurisdiction Files available on the Oracle website.
- Navigate to the installed directory of PowerChute Network Shutdown. If the default location was chosen during installation, this will be C:\Program Files (x86)\APC\PowerChute or C:\Program Files\APC\PowerChute depending on your operating system.
- Navigate to \<jre>\lib\security and replace the existing Policy Files with the ones extracted in Step 1.
- This folder will be named jre_x64 or jre_x86 depending on your operating system.
- Restart the PowerChute Network Shutdown service.
NOTE: This issue is resolved in PowerChute Network Shutdown v4.4 which uses OpenJDK 14.
