Overview

This project contains source code associated with the OpenJCEPlus and OpenJCEPlusFIPS cryptographic providers that can be used within a Java SDK. At this time, this project intends to only issue source code releases which will not include any binary distribution format. These cryptographic providers contain capabilities to support JCE cryptographic operations using the Open Crypto Kit cryptographic library.

IMPORTANT NOTE: Although this project uses the term "FIPS" in different code paths and naming conventions the code and binary files derived from this code CANNOT be considered FIPS compliant. Achieving certified FIPS cryptography requires the underlying library binary to be FIPS certified for specific platforms and architectures. Any cryptographic libraries developed must adhere to rigorous FIPS standards and should not be assumed to be available in any environment. All environments and binaries must undergo the FIPS certification process with NIST to ensure compliance.

This github branch can only be used with the latest generally available version of Java.

Build Status:

How to Build OpenJCEPlus and Java Native Interface Library

OpenJCEPlus and OpenJCEPlusFIPS providers are currently supported on the following architectures and operating system combinations as reported by mvn --version in the values OS name and arch:

OS name	arch
linux	amd64
linux	s390x
linux	ppc64le
Windows Server 2022	amd64
AIX	ppc64
Mac OS X*	aarch64*

• Mac OS X currently is only able to compile and run tests using the OpenJCEPlus provider, not OpenJCEPlusFIPS. The provider OpenJCEPlusFIPS will not load.

Follow these steps to build the OpenJCEPlus and OpenJCEPlusFIPS providers along with a dependent Java Native Interface library. Keep in mind that $PROJECT_HOME can represent any directory on your system and will be referred to as such in the subsequent instructions:

1. Create an OCK directory, for example:

   mkdir $PROJECT_HOME/OCK

2. Extract the Java gskit SDK tar and gskit tar file into the directory previously created:

   cd $PROJECT_HOME/OCK
   tar xvf jgsk_crypto_8_9_3_0_sdk.tar
   tar xvf jgsk_crypto_8_9_3_0.tar

3. Copy the OCK library referred to as ICC to the correct location:

   Create the lib64 directory and copy the libjgsk8iccs_64.so library to that location:

   mkdir $PROJECT_HOME/OCK/jgsk_sdk/lib64
   cp $PROJECT_HOME/OCK/libjgsk8iccs_64.so $PROJECT_HOME/OCK/jgsk_sdk/lib64

   On AIX copy the library to the jgsk_sdk directory in addition to the lib64 directory above.

   cp $PROJECT_HOME/OCK/libjgsk8iccs_64.so $PROJECT_HOME/OCK/jgsk_sdk

   On Mac:

   mkdir $PROJECT_HOME/OCK/jgsk_crypto_sdk/jgsk_sdk/lib64
   cp $PROJECT_HOME/OCK/jgsk_crypto/libjgsk8iccs_64.so $PROJECT_HOME/OCK/jgsk_crypto_sdk/jgsk_sdk/lib64

4. Install Maven and place the command in your PATH. These instructions are OS dependant. It is recommended to make use of version 3.9.2, although other versions of Maven are known to work. You can test your installation by issuing mvn --version. For example:

   $ mvn --version
   Apache Maven 3.9.2 (c9616018c7a021c1c39be70fb2843d6f5f9b8a1c)
   Maven home: /tools/apache-maven-3.9.2
   Java version: 1.8.0_361, vendor: IBM Corporation, runtime: /opt/ibm/sdks/jdk-21.0.2+13
   Default locale: en_US, platform encoding: ISO8859-1
   OS name: "aix", version: "7.2", arch: "ppc64", family: "unix"

5. Clone the OpenJCEPlus respository.

6. Change directory to the root directory where the pom.xml file exists.

   cd OpenJCEPlus

7. Set your JAVA_HOME environment variable. This will be the SDK used to compile the project. You must set your JAVA_HOME value to the latest generally available version of Java when using code located in the main branch.

   export JAVA_HOME="/opt/ibm/sdks/jdk-21.0.2+13"

8. Set the location of the variable GSKIT_SDK to the directory extracted in the above steps.

   export GSKIT_HOME="$PROJECT_HOME/OCK/jgsk_sdk"

   On Mac:

   export GSKIT_HOME="$PROJECT_HOME/OCK/jgsk_crypto_sdk/jgsk_sdk"

9. (Only for Windows) Some additional environment variables need to be set in Windows. There are certain header files and libraries that are required to build the OpenJCEPlus and OpenJCEPlusFIPS providers in a Windows environment and those files are found in the exported directories. It is assumed that you are running through a CYGWIN prompt.

   export PATH=/cygdrive/c/Program\ Files\ \(x86\)/Windows\ Kits/10/bin/10.0.19041.0/x64/:/cygdrive/c/Program\ Files/Microsoft\ Visual\ Studio/2022/Professional/VC/Tools/MSVC/14.31.31103/bin/Hostx64/x64/:$PATH
   
   export INCLUDE="C:/Program Files (x86)/Windows Kits/10/include/10.0.19041.0/um/;C:/Program Files (x86)/Windows Kits/10/include/10.0.19041.0/shared/;C:/Program Files/Microsoft Visual Studio/2022/Professional/VC/Tools/MSVC/14.31.31103/include/;C:/Program Files (x86)/Windows Kits/10/include/10.0.19041.0/ucrt/"
   
   export LIB="C:/Program Files/Microsoft Visual Studio/2022/Professional/VC/Tools/MSVC/14.31.31103/lib/x64;C:/Program Files (x86)/Windows Kits/10/lib/10.0.19041.0/ucrt/x64;C:/Program Files (x86)/Windows Kits/10/lib/10.0.19041.0/um/x64"

   NOTE 1: You need to have installed Microsoft Visual Studio and CYGWIN on your machine.

   NOTE 2: You might have to adapt the exported environment variables, if the installation directory of Visual Studio is different on your machine, or the versions you have available for Windows Kits and Visual Studio are diffent (e.g., the Windows Kits version in the variables above is 10.0.19041.0, but it might be different on your machine).

10. Compile the OpenJCEPlus and OpenJCEPlusFIPS providers along with the Java Native Interface library. This command intentionally skips test execution. See instructions below for running tests.

    mvn '-Dock.library.path=$PROJECT_HOME/OCK/' install -DskipTests

    On Mac:

    mvn '-Dock.library.path=$PROJECT_HOME/OCK/jgsk_crypto' install -DskipTests

Test Execution

Tests are available within the OpenJCEPlus repository. These Junit tests can be run in various ways including running individual tests or the entire test suite.

Run all tests

On AIX you must set an additional setting for the LIBPATH environment variable:

export LIBPATH="$PROJECT_HOME/OCK/:$PROJECT_HOME/OCK/jgsk_sdk"

On all platforms set the following environment variables and execute all the tests using mvn. You must set your JAVA_HOME value to the latest generally available version of Java when using code located in the main branch.

export JAVA_HOME="$JAVA_INSTALL_DIRECTORY/jdk-21.0.2+13"
export GSKIT_HOME="$PROJECT_HOME/OCK/jgsk_sdk"
mvn '-Dock.library.path=$PROJECT_HOME/OCK/' test

NOTE: When using a JDK that doesn't have OpenJCEPlus bundled with it, you might notice a few warnings like WARNING: Unknown module: openjceplus specified to --add-exports. There is no need to worry as they do not affect execution of tests or the build itself.

Run single test

On AIX you must set an additional setting for the LIBPATH environment variable:

export LIBPATH="$PROJECT_HOME/OCK/:$PROJECT_HOME/OCK/jgsk_sdk"

On all platforms change to the OpenJCEPlus directory and set the following environment variables and execute a specific test name using mvn. You must set your JAVA_HOME value to the latest generally available version of Java when using code located in the main branch.

cd OpenJCEPlus
export JAVA_HOME="$JAVA_INSTALL_DIRECTORY/jdk-21.0.2+13"
export GSKIT_HOME="$PROJECT_HOME/OCK/jgsk_sdk"
mvn '-Dock.library.path=$PROJECT_HOME/OCK/' test -Dtest=TestClassname

OpenJCEPlus and OpenJCEPlusFIPS Provider SDK Installation

1. Modify your java.security file located in the $JAVA_HOME/conf/security directory by adding one of the following providers. The value XX below represents your desired preference order.

   security.provider.XX=com.ibm.crypto.plus.provider.OpenJCEPlusFIPS
   security.provider.XX=com.ibm.crypto.plus.provider.OpenJCEPlus

2. Execute your application specifying the openjceplus.jar, the location of the OCK library, and the location of the jgskit library as follows.

   -Xbootclasspath/a:$ANYDIRECTORY/openjceplus.jar

   '-Dock.library.path=$PROJECT_HOME/OCK/'

   -Djgskit.library.path=$ANYDIRECTORY
