Barreto-Naehrig curve implementation and BLS

Install

Requirements

Your system needs have installed first llvm, g++, gmp and openssl{-dev}. On Ubuntu:

sudo apt install llvm g++ libgmp-dev libssl-dev

From source

To install from source, you can run the following commands:

git clone https://github.com/dfinity/bn
cd bn
make
make install

The library is then installed under /usr/local/. In order to use it as a library for any project (see go-dfinity-crypto for example), your loader must be aware of this location. There are two common solutions:

  • To use it for the current session:
export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib
  • To use it permanently, add /usr/local/lib to /etc/ld.so.conf , then run ldconfig as root

If you wish to change the path where the libraries are installed, you can use:

make install PREFIX=/my/custom/path

From latest release

Prebuilt libraries are available for select platforms.

You may need to place the libraries in the correct path as explained in the above section.
