# libeosio
Independent C++ library for [EOS](https://eos.io/)
NOTE: This repository has no connection to the official EOS code.
## Compiling the library
You will need `openssl` development files (version 1.1 or later) to compile and `cmake 3.15` or later to compile this project.
### CMake
You can install `cmake` by reading the [official guide](https://cmake.org/install).
### Linux
#### Dependencies
**Ubuntu (or other debian based distros)**
First you need to have a compiler, `openssl` and `cmake`. this can be installed with apt.
```sh
$ apt-get install gcc g++ cmake libssl-dev
```
If you need a newer version of cmake then apt provides.
Checkout the official [CMake APT repository](https://apt.kitware.com/).
**Other**
Consult your package manager's manual for getting `openssl`,`g++` and `cmake` installed.
If you need a newer version of cmake then your package manager provides. checkout the [official guide](https://cmake.org/install).
### MacOS
#### Dependencies
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 openssl and cmake installed also, this can be done with this `brew` command:
```sh
$ brew install openssl cmake
```
If you need a newer version of cmake then brew provides. checkout the [official guide](https://cmake.org/install)
#### Build
```sh
$ 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
First you will need a compiler.
[Build Tools for Visual Studio 2019](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools&rel=16) (Selecting C++ during installation) is recommended.
By default `cmake` will use the bundled openssl package located at `vendor/openssl-1.1.1e-win-static.zip`
If you like to use an other version of OpenSSL then the static one bundled with this repo
you need to set `OPENSSL_ROOT_DIR` to the directory where OpenSSL is located on the system.
For example:
```
C:\repo> cmake -D OPENSSL_ROOT_DIR=C:/path/to/openssl -B build
```
**NOTE:** `cmake` uses forward slash `/` for path even for windows. so make sure you use that when setting `OPENSSL_ROOT_DIR`
#### Build.
Run cmake
```
C:\repo> cmake -B build
C:\repo> cmake --build build --config Release
```
## 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)
Please read the `LICENSE` file.
