The base Java JVM and SDK installs from Oracle are limited in strength for the cryptographic functions that they can perform. Oracle also provide a patch the "Java JCE Unlimited Strength Jurisdiction Policy Files" patch which when applied to the base JDK or JVM install allows for unlimited strength cryptographic functions.
Although the patch is a simple zip file there are often problems associated with installing it and installing it in the right location. This article covers how to do the install of the patch, and also some of the mis-install pitfalls that can occur.
Applies to Symantec SiteMinder 12.8.x
Instructions:
The Java Cryptography Extension enables applications to use stronger versions of cryptographic algorithms. JDK 9 and later offer the stronger cryptographic algorithms by default.
The unlimited policy files are required only for JDK 8, 7, and 6 updates earlier than 8u161, 7u171, and 6u181. On those versions and later, the stronger cryptographic algorithms are available by default.
