Additional libraries needed for strong ciphers

Some cryptographic algorithms are not supported by the default installation of JSCAPE MFT Synchronizer. For example, you can't generate keys with key lengths greater than 1024 with just the default installation.

To support a wider range of cryptographic algorithms and longer keys, you need to install the JCE Unlimited Strength Jurisdiction Policy Files distributed by Oracle.

Due to export restrictions, the version of the policy files bundled by default with older versions of the JDK allow "strong" but limited cryptography to be used.  The "unlimited strength" policy files contain no restrictions on the cryptographic strengths.

As indicated in the Oracle website, JDK 9 and later already ship with, and use by default, the unlimited policy files. Policy files for JDK 8 are accessible from the link below.

Installation

1.  Determine the location of the JVM/JDK you are using by opening the .install4j\inst_jre.cfg file located in your JSCAPE MFT Synchronizer installation directory.  This  file will contain the path to the JRE used when running JSCAPE MFT Synchronizer.

Example

c:\program files\java\jre

2. Extract the contents of the Unlimited Strength Jurisdiction Policy Files to a temporary directory.

3. Copy the local_policy.jar and US_export_policy.jar files extracted in the previous step to the lib\security directory of your JRE making sure to backup previous versions of these jar files should you decide to revert back to the previous installation.  

Example

c:\program files\java\jre\lib\security

4.  Restart both the JSCAPE MFT Synchronizer service and JSCAPE MFT Synchronizer Manager.
