EOSIO Keygen

This program generates public and private keypair for EOS

Compile

You will need libeosio and cmake 3.15 or later to compile this project.

Linux/MacOS

Dependencies

Linux

Ubuntu:

First you need to have a compiler. this can be installed with apt.

$ apt-get install gcc g++

CMake

If your package manager don't provide a sufficiently new version of cmake, you can install it with these commands:

Ubuntu 16.04/18.04 - kitware ppa:

$ wget -O - https://apt.kitware.com/keys/kitware-archive-latest.asc 2>/dev/null | sudo apt-key add -
$ sudo apt-add-repository "deb https://apt.kitware.com/ubuntu/ `lsb_release -cs` main"
$ sudo apt-get install cmake

shell script:

$ wget -O cmake.sh https://github.com/Kitware/CMake/releases/download/v3.15.5/cmake-3.15.5-Linux-x86_64.sh && sudo sh ./cmake.sh --prefix=/usr/local --skip-license

Other methods is documanted at https://cmake.org/download

MacOS

You must have a compiler installed. This project is known to build with Xcode 11.0 but other versions should work.

You need to have cmake installed also, this can be done with this brew command:

$ brew install cmake

If you need a newer version of cmake, you can download the official .dmg file: cmake-3.15.7-Darwin-x86_64.dmg. or see https://cmake.org/download for other versions.

libeosio needs to be compiled and installed from source. Go here

Build

Run ./build.sh to trigger cmake.

If you dont want to use the script. you can build with cmake using the following commands:

$ mkdir build && cd build
$ cmake .. && make

MacOS: You may need to point cmake to openssl by passing the argument -D OPENSSL_ROOT_DIR=/usr/local/opt/openssl@1.1 if openssl is not under /usr/local/opt/openssl@1.1 you need to find the correct path.

Windows

Dependencies

Download and install cmake version 3.15 or newer from cmake.org

You will also need a compiler. Build Tools for Visual Studio 2019 (Selecting C++ during installation) is recommended.

Build.

you need to set OPENSSL_ROOT_DIR to the directory where you unpacked openssl-1.1.1e-dev.zip append x86 if you are on 32-bit system, x64 for 64-bit.

NOTE: cmake uses forward slash / for path even for windows. so make sure you use that when setting OPENSSL_ROOT_DIR

For example:

C:\repo> mkdir build
C:\repo> cd build
C:\repo\build> cmake -D OPENSSL_ROOT_DIR="C:/path/to/openssl-1.1/x86" ..
C:\repo\build> cmake --build . --config Release

Compile options

These compile options are available:

Cmake	build.sh	Description
-DCOMPONENT_CLI=OFF	--no-cli	Do not build cli program
-DCOMPONENT_GUI=ON	--gui	Build gui program (Qt5)
-DUSE_THREADS=OFF	--disable-threads	Disable thread support
-DCMAKE_BUILD_TYPE=value	-t value	Type of build
-DFORCE_ANSI=ON	--force-ansi	Force ANSI console colors even on windows

For more details about options run ./build.sh -l or mkdir build && cmake build -LA

libeosio

To speed up the build process, you can install libeosio

Ubuntu

You can use EOS Sweden's APT Repository like this:

$ sudo apt-get install software-properties-common
$ curl https://apt.eossweden.org/key 2> /dev/null | sudo apt-key add -
$ sudo apt-add-repository -y 'deb [arch=amd64] https://apt.eossweden.org/main `lsb_release -cs` stable'
$ sudo apt-get install libeosio-dev

or manually via .deb file from github

$ wget <url>
$ sudo apt install ./libeosio-dev-<version>.deb

Other

Consult libeosio's github

Install

After the project has been compiled. run sudo ./install.sh or the following code if you dont want to use that:

# inside the build directory
$ sudo make install

Windows:

It is possible to run cmake --install . from build directory. Your DOS shell needs administrator privileges.

Uninstall

Run sudo ./uninstall.sh or remove the files listed in build/install_manifest.txt manually.

Security notice

Keys are generated by OpenSSL's EC_KEY_generate_key function. The program will never expose your keys to anything but the computers memory and output of the program. You are free to inspect the source code and compile yourself to verify.

However, use this at your own risk. we cannot guarantee that the keys are cryptographically secure as this depends on OpenSSL's implementation (alto it is widely used and should be safe)
