Concise Binary Object Representation is an Internet Standard, see [STD94] below.

[STD94]

Internet Standard 94, <https://www.rfc-editor.org/info/std94>. At the time of writing, this STD comprises the following:

Bormann, C. and P. Hoffman, "Concise Binary Object Representation (CBOR)", STD 94, RFC 8949, DOI 10.17487/RFC8949, December 2020, <https://www.rfc-editor.org/info/rfc8949>.

Tested on

• macOS 26
• macOS 15.5
• ubuntu 24.04

Dependencies

Requires

• A C++ compiler supporting C++23
• GNU Autoconf
• GNU Automake
• GNU Autogen
• GNU Libtool
• DejaGnu

Check out

git clone https://github.com/glvi/cbor_cpp

Build from source

autoreconf -fis
mkdir -p build
(cd build && ../configure CXXFLAGS=-std=c++23 CPPFLAGS=-I/usr/local/include)
gmake -j -C build check

You can choose any other name for the build directory.

Modify CXXFLAGS accordingly, if your compiler uses a different directive to support C++23, or if you want to specify additional compiler flags.

Modify CPPFLAGS accordingly, if your installation of DejaGnu resides in a different location, or if you want to specify additional preprocessor flags.

Information security

The scanner has protection against excessive counts of bytes in byte strings or text strings, or excessive counts of elements in arrays or maps. These counts can be changed at the level of the configure script. See configure --help for options --enable-cbor-bstr/tstr/array/map-count-max. Default values are as follows.

Type	Max	Unit
bstr	32768	bytes
tstr	32768	bytes
array	1024	elements
map	512	pairs of elements
