It's best to install NTL from source rather than using Homebrew or any Linux package manager. I found that Homebrew was missing some important NTL routines because of an old version.
- Download NTL: NTL Download
- Installation Instructions: NTL Unix Installation
% gunzip ntl-xxx.tar.gz
% tar xf ntl-xxx.tar
% cd ntl-xxx/src
% ./configure
% make
% make check
% sudo make install
The homebrew installation appears to be current:
OpenSSL is already likely installed, but if not, follow directions on this site for your specific distribution: https://docs.openiam.com/docs-4.2.1.3/appendix/2-openssl
- After Dependencies are installed
- Clone the Repository
- CD into the directory and run
make - The Binary is called crypto_pk
git clone https://github.com/0x0M03II/public-key.git
cd public-key
make
./crypto_pk
There are two independent projects, RSA and Diffie-Hellman. Within the main() function, you can comment or uncomment one or both of DiffieHellmanAssignment() and RSAAssignment(). For example, if you want to run just the RSA and don't want to wait for DH, comment out DiffieHellmanAssignment().
This depends on the NTL library being present in /usr/local/lib/. If you follow the directions for installing NTL provided above, the library will automatically be installed. If you have a previous Homebrew installation of NTL, you may need to remove it and delete the symbolic links for the library in /usr/local/lib. I originally installed using Homebrew, but it was missing important functions like RandomBits_ZZ(). After running brew uninstall, the symbolic links to the brew installation of the NTL library were still present in /usr/local/lib, and compiling from source will not delete these; it will just assume the library is present and ignore.
