    A library that implements the client-side of the ACVP protocol.
    The ACVP specification is a work-in-progress and can be found at
    https://github.com/usnistgov/ACVP

License

Libacvp is licensed under the Apache License 2.0, which means that you are free to get and use it for commercial and non-commercial purposes as long as you fulfill its conditions. See the LICENSE file for details.

Recent Changes!

The client library is compatible with the ACVP spec version 1.0, see https://github.com/usnistgov/ACVP however not all algorithms and options are supported. See the support list in the Supported Algorithms section below.

Metadata processing has been simplified and no longer requires id fields. Please review the new metadata directory sample json files to see the new format. Older formats should continue to work, but will have some unused keywords and fields.

To track any and all changes please review recent commits for more detail.

Overview

Libacvp is a client-side ACVP library implementation, and also includes an example application which utilizes the library.

libacvp will login and then register with the ACVP server (advertising capabilities) The server will respond with a list of vector set identifiers that need to be processed. libacvp will download each vector set, process the vectors, and send the results back to the server. This is performed in real-time by default. The user can also use "offline" mode for non-realtime processing.

The app/ directory contains a sample application which uses libacvp. This app provides the glue between the crypto module DUT and the library itself. Depending upon the DUT, the crypto backend API, and other factors, the user may need to enhance the reference application, or create a new one from scratch.

The application within app/ is only provided here for unit testing and demonstrating how to use libacvp. The application layer (app_main.c) is required to interface with the crypto module that will be tested. In this example it uses OpenSSL, which introduces libcrypto.so as the DUT.

The library also provides an example on how a standalone module could be tested. In this case it uses the OpenSSL FOM canister. The FOM canister has a few algorithms that can only be tested when not running in a final product. These algorithms can be tested under this configuration. The FOM build also requires the path to the canister header files and object which is defined in the ./configure CLI to enable non-runtime shown below which automatically adds the compile time flag -DACVP_NO_RUNTIME.

The certs/ directory contains the certificates used to establish a TLS session with well-known ACVP servers. If the ACVP server uses a self-signed certificate, then the proper CA file must be specified. libacvp also requires a client certificate and key pair, which the ACVP server uses to identify the client. You will need to contact NIST to register your client certificate with their server.

The murl directory contains experimental code to replace the Curl dependency. This may be useful for target platforms that don't support Curl, such as Android or iOS. Murl is a "minimal" Curl implementation. It implements a handful of the Curl API entry points used by libacvp. The Murl code is currently in an experimental stage and is not supported or maintained as part of libacvp and should not be used in any production environment.

Dependencies

  • autotools
  • gcc
  • make
  • curl (or substitution)
  • openssl (or substitution)

Curl is used for sending REST calls to the ACVP server.

Openssl is used for TLS transport by libcurl.

Parson is used to parse and generate JSON data for the REST calls. The parson code is included and compiled as part of libacvp.

libcurl, libssl and libcrypto are not included, and must be installed separately on your build/target host, including the header files.

Dealing with system-default dependencies

This codebase uses features in OpenSSL >= 1.0.2. If the system-default install does not meet this requirement, you will need to download, compile and install at least OpenSSL 1.0.2 on your system. The new OpenSSL resources should typically be installed into /usr/local/ssl to avoid overwriting the default OpenSSL that comes with your distro.

It is highly recommended to use versions of OpenSSL 1.1.1 or greater when possible, as all previous versions have reached end of life status.

The next problem is the default libcurl on the Linux distro may be linked against the previously mentioned default OpenSSL. This could result in linker failures when trying to use the system default libcurl with the new OpenSSL install (due to missing symbols). Therefore, you SHOULD download the Curl source, compile it against the "new" OpenSSL header files, and link libcurl against the "new" OpenSSL. libacvp uses compile time macro logic to address differences in the APIs of different OpenSSL versions.

Building

--prefix<path to install dir> can be used with any configure options to specify where you would like the library and application to install to.

To build for runtime testing

./configure --with-ssl-dir=<path to ssl dir> --with-libcurl-dir=<path to curl dir>
make clean
make
make install

To build for non-runtime testing

./configure --with-ssl-dir=<path to ssl dir> --with-libcurl-dir=<path to curl dir> --with-fom_dir=<path to where FOM is installed>
make clean
make
make install

Cross Compiling

Requires options --build and --host. Your $PATH must contain a path the gcc.

export CROSS_COMPILE=powerpc-buildroot-linux-uclibc
./configure --build=<local target prefix> --host=<gcc prefix of target host> --with-ssl-dir=<path to ssl dir> --with-libcurl-dir=<path to curl dir>

Example with build and host information:

./configure --build=localx86_64-unknown-linux-gnu --host=mips64-octeon-linux-gnu --with-ssl-dir=<path to ssl dir> --with-libcurl-dir=<path to curl dir>`

All dependent libraries must have been built with the same cross compile.

If using murl for cross compliles use the same CROSS_COMPILE and HOSTCC used with openssl, for example:

CROSS_COMPILE=arm-linux-gnueabihf- HOSTCC=gcc

Windows

  1. Modify and run scripts/gradle_env.bat
  2. Run gradle build
  3. Modify and run scripts/nist_setup.bat

After successfully completing, the .dll and .lib library files are loacted in build/libs/acvp and the example executable is located in build/exe/. Note: Windows executables require that dependent libraries be in very specific locations (or in the Windows path). One of these locations is the base directory of the executable.

Running

  1. export LD_LIBRARY_PATH=<path to ssl lib>
  2. Modify and run scripts/nist_setup.sh
  3. ./app/acvp_app --<options>

Use ./app/acvp_app --help for more information on available options.

How to test offline

  1. Download vectors on network accessible device: ./app/acvp_app --<algs of choice or all_algs> --vector_req <filename1>
  • where is the file you are saving the tests to.
  1. Copy vectors and acvp_app to target: ./app/acvp_app --all_algs --vector_req <filename1> --vector_rsp <filename2>
  • where is the file the tests are saved in, and is the file you want to save your results to.
  1. Copy respones(filename2) to network accessible device: ./app/acvp_app --all_algs --vector_upload <filename2>
  • where is the file containing the results of the tests.

Note: If the target in Step 2 does not have the standard libraries used by libacvp you may configure and build a special app used only for Step 2. This can be done by using --enable-offline and --enable-static when running ./configure and do not use --with-libcurl-dir or --with-libmurl-dir which will minimize the library dependencies. Note that openssl with FOM must also be built as static.

For example:

export FIPSLD_CC=gcc     (or whatever compiler is being used)
./configure --with-ssl-dir=<ciscossl install> --with-fom-dir=<fom install> --prefix=<libacvp install> --enable-static --enable-offline

Testing

Move to the test/ directory and see the README.md there. The tests depend upon a C test framework called Criterion, found here: https://github.com/Snaipe/Criterion

Contributing

Before opening a pull request on libacvp, please ensure that all unit tests are passing. Additionally, new tests should be added for new library features.

We also run the uncrustify tool as a linter to keep code-style consistent throughout the library. That can be found in the uncrustify/ directory.

FAQ

I get "unable to process test vectors" for certain algorithms when libacvp is built without a FOM. Why? Some algorithms need to have internal mechanisms tested that are not available in the regular APIs for that algorithm. These cannot be tested at runtime and are only avaible to be tested when linked to a FOM for non-runtime testing. --all_algs attempts to run these algorithms as well, so for runtime testing without linking to a FOM, specify the algorithms you wish to run individually.

I get some sort of hard crash while processing vector sets - why? It is probable that libacvp is linking to a different version of a library than the one it was configured and built with. libacvp/acvp_app depend on library versions in enabling or disabling certain features at build time, so please make sure libacvp and acvp_app are built and run with the same versions of each library.
