C library implementing the Javascript Object Signing and Encryption (JOSE)

cjose

Implementation of JOSE for C/C++

Prerequisites

MAC OS X All of the prerequisites can be installed via brew.

Build Tools

• pkg-config (>= 0.20)
• GNU Make >= 3.81
• LLVM >= 5.1 or GCC >= 4.5
• Autoconf (>= 2.69)
• Automake (>= 1.14)
• libtool (>= 2.4)
• Check (>= 0.9.4) - unit testing (e.g. check-devel)
• Doxygen (>= 1.8) - documentation
• clang-format (= 3.9.0)

Libraries

• OpenSSL >= 1.0.1h (or its API equivalent)
• Jansson >= 2.3

Getting Started

As with most autoconf/automake projects:

git clone https://github.com/cisco/cjose.git
cd cjose
./configure && make

Common Options

--with-openssl: Specify the location where OpenSSL/CiscoSSL is installed
--with-jansson: Specify the location where Jansson is installed
--disable-shared: Only build static library

Debug Mode

To compile in debug mode (minimal optimization, active asserts, etc), specify the appropriate CFLAGS as a command-line argument when executing configure:

./configure CFLAGS="-g -O0 -DDEBUG"

Tests

To execute the unit tests:

make test

If successful, the list of checks will be displayed on the console. Otherwise, the file "test/test-suite.log" will list the specific test(s) that failed.

API Docs

To generate Doxygen API documentation:

make doxygen

Which will place the generated documentation in "doc/html".

From Scratch

To rebuild all of the project -- including those files generated by autoconf and automake:

autoreconf --force --install

Troubleshooting

Configure can't find check.h header file.

This has been seen on Mac OSX 10.8 and 10.9 when check has been installed via brew. A solution is to explicitly include the /usr/local/include directory in the cflags:

./configure CFLAGS="-I/usr/local/include"

Make fails due to many OpenSSL functions being "deprecated" or missing.

This has been seen on Mac OSX 10.9 when openssl 1.0.1h or newer has been installed via brew. A solution is to explicitly include the openssl directory in the configure command:

./configure --with-openssl=/usr/local/opt/openssl

Make fails due to json_* functions missing.

This has been seen on Mac OSX 10.9 when Jansson has been installed via brew. A solution is to explicitly include the jansson directory in the configure command:

./configure --with-jansson=/usr/local/opt/jansson
