Signing and Verify can be fasten (200 %) by installing cryptography:

pip install -U cryptography

Install beem by pip:

pip install -U beem

You can install beem from this repository if you want the latest but possibly non-compiling version:

git clone https://github.com/holgern/beem.git
cd beem
python setup.py build

python setup.py install --user

Run tests after install:

pytest

Installing beem with conda-forge

Installing beem from the conda-forge channel can be achieved by adding conda-forge to your channels with:

conda config --add channels conda-forge

Once the conda-forge channel has been enabled, beem can be installed with:

conda install beem

conda install cryptography

CLI tool beempy

A command line tool is available. The help output shows the available commands:

beempy –help

Stand alone version of CLI tool beempy

With the help of pyinstaller, a stand alone version of beempy was created for Windows, OSX and linux. Each version has just to be unpacked and can be used in any terminal. The packed directories can be found under release. Each release has a hash sum, which is created directly in the build-server before transmitting the packed file. Please check the hash-sum after downloading.
