Jce_policy installing the "Java Password Extensions unrestricted rights policy File installation"

To download the JCE package with the corresponding version of JDK or JRE, the JDK currently requires the machine to be 1.8, so download jce_policy-8.zip.

：

After downloading the extract, upload the jar file to the security directory where you need to install the JDK or JRE on the JCE machine, overwriting the source file.

JDK: Two jar files are also placed under%jdk_home%\jre\lib\security

JRE: Place two jar files under%jre_home%\lib\security

Before overwriting, remember to back up the source files just in case.
