Unlimited Strength Java(TM) Cryptography Extension Policy Files for the Java(TM) Platform, Standard Edition Runtime Environment 8 README ---------------------------------------------------------------------- CONTENTS ---------------------------------------------------------------------- o Introduction o License and Terms o Understanding The Export/Import Issues o Where To Find Documentation o Installation o Questions, Support, Reporting Bugs ---------------------------------------------------------------------- Introduction ---------------------------------------------------------------------- Thank you for downloading the Unlimited Strength Java(TM) Cryptography Extension (JCE) Policy Files for the Java(TM) Platform, Standard Edition (Java SE) Runtime Environment 8. Due to import control restrictions of some countries, the version of the JCE policy files that are bundled in the Java Runtime Environment, or JRE(TM), 8 environment allow "strong" but limited cryptography to be used. This download bundle (the one including this README file) provides "unlimited strength" policy files which contain no restrictions on cryptographic strengths. Please note that this download file does NOT contain any encryption functionality as all such functionality is contained within Oracle's JRE 8. This bundles assumes that the JRE 8 has already been installed. ---------------------------------------------------------------------- License and Terms ---------------------------------------------------------------------- This download bundle is part of the Java SE Platform products and is governed by same License and Terms notices. These notices can be found on the Java SE download site: http://www.oracle.com/technetwork/java/javase/documentation/index.html ---------------------------------------------------------------------- Understanding The Export/Import Issues ---------------------------------------------------------------------- JCE for Java SE 8 has been through the U.S. export review process. The JCE framework, along with the various JCE providers that come standard with it (SunJCE, SunEC, SunPKCS11, SunMSCAPI, etc), is exportable. The JCE architecture allows flexible cryptographic strength to be configured via jurisdiction policy files. Due to the import restrictions of some countries, the jurisdiction policy files distributed with the Java SE 8 software have built-in restrictions on available cryptographic strength. The jurisdiction policy files in this download bundle (the bundle including this README file) contain no restrictions on cryptographic strengths. This is appropriate for most countries. Framework vendors can create download bundles that include jurisdiction policy files that specify cryptographic restrictions appropriate for countries whose governments mandate restrictions. Users in those countries can download an appropriate bundle, and the JCE framework will enforce the specified restrictions. You are advised to consult your export/import control counsel or attorney to determine the exact requirements. ---------------------------------------------------------------------- Where To Find Documentation ---------------------------------------------------------------------- The following documents may be of interest to you: o The Java(TM) Cryptography Architecture (JCA) Reference Guide at: http://docs.oracle.com/javase/8/docs/technotes/guides/security o The Java SE Security web site has more information about JCE, plus additional information about the Java SE Security Model. Please see: http://www.oracle.com/technetwork/java/javase/tech/index-jsp-136007.html ---------------------------------------------------------------------- Installation ---------------------------------------------------------------------- Notes: o Unix (Solaris/Linux/Mac OS X) and Windows use different pathname separators, so please use the appropriate one ("\", "/") for your environment. o <java-home> (below) refers to the directory where the JRE was installed. It is determined based on whether you are running JCE on a JRE or a JRE contained within the Java Development Kit, or JDK(TM). The JDK contains the JRE, but at a different level in the file hierarchy. For example, if the JDK is installed in /home/user1/jdk1.8.0 on Unix or in C:\jdk1.8.0 on Windows, then <java-home> is: /home/user1/jdk1.8.0/jre [Unix] C:\jdk1.8.0\jre [Windows] If on the other hand the JRE is installed in /home/user1/jre1.8.0 on Unix or in C:\jre1.8.0 on Windows, and the JDK is not installed, then <java-home> is: /home/user1/jre1.8.0 [Unix] C:\jre1.8.0 [Windows] o On Windows, for each JDK installation, there may be additional JREs installed under the "Program Files" directory. Please make sure that you install the unlimited strength policy JAR files for all JREs that you plan to use. Here are the installation instructions: 1) Download the unlimited strength JCE policy files. 2) Uncompress and extract the downloaded file. 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) Install the unlimited strength policy JAR files. 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] ----------------------------------------------------------------------- Questions, Support, Reporting Bugs ----------------------------------------------------------------------- Questions --------- For miscellaneous questions about JCE usage and deployment, we encourage you to read: o Information on the Java SE Security web site http://www.oracle.com/technetwork/java/javase/tech/index-jsp-136007.html o The Oracle Online Community Forums, specifically the Java Cryptography forum.
