如何在MacOS Sierra上安装JCE for JRE 8？

Question

我想安装https://github.com/cryptomator/cli要求： JRE 8：http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html JCE：http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html

我的Mac上，首选项>的Java，Java选项卡，我看到平台1.8，产品1.8.0_121，以及1.8 1.8的路径.0_121 http://java.sun.com/products/autodl/j2se/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java

所以我认为我已经有了JRE 8。我如何知道我是否有JCE，如果它不在那里，我该如何正确安装它？

Answer 1

以下是安装说明：

1）下载无限强度的JCE策略文件。

2）解压并解压下载的文件。

This will create a subdirectory called jce. 
This directory contains the following files: 

    README.txt     This file 
    local_policy.jar    Unlimited strength local policy file 
    US_export_policy.jar   Unlimited strength US export policy file 

3）安装无限强度策略JAR文件。

In case you later decide to revert to the original "strong" but 
limited policy versions, first make a copy of the original JCE 
policy files (US_export_policy.jar and local_policy.jar). Then 
replace the strong policy files with the unlimited strength 
versions extracted in the previous step. 

The standard place for JCE jurisdiction policy JAR files is: 

    <java-home>/lib/security   [Unix] 
    <java-home>\lib\security   [Windows] 

它在的README.txt在那里你可以得到它，你下载的zip文件（jce_policy-8.zip）显然经过解释。
