The minimal working python version is 2.7.x. or 3.4.x

crea can be installed parallel to python-crea.

For Debian and Ubuntu, please ensure that the following packages are installed:

sudo apt-get install build-essential libssl-dev python-dev

For Fedora and RHEL-derivatives, please ensure that the following packages are installed:

sudo yum install gcc openssl-devel python-devel

For OSX, please do the following:

brew install openssl
export CFLAGS="-I$(brew --prefix openssl)/include $CFLAGS"
export LDFLAGS="-L$(brew --prefix openssl)/lib $LDFLAGS"

For Termux on Android, please install the following packages:

pkg install clang openssl-dev python-dev

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

pip install -U cryptography

or:

pip install -U secp256k1prp

Install or update crea by pip:

pip install -U crea

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

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

python setup.py install --user

Run tests after install:

pytest

Installing crea with conda-forge

Installing crea 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, crea can be installed with:

conda install crea

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

conda install cryptography

crea can be updated by:

conda update crea

CLI tool creapy

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

creapy –help

Stand alone version of CLI tool creapy

With the help of pyinstaller, a stand alone version of creapy 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.

Changelog
