Python Implementation of the KERI Core Libraries

Project Name: keripy

Installation

Local installation - build from source

Once all dependencies are installed and working then run:

$ python3 -m pip install -e ./

Then you can run

$ kli version

to get a version string similar to the following:

1.0.0

Local installation - Docker build

Run make build-keri to build your docker image.

Then run docker run -it gleif/keri /bin/bash and you can run kli version from within the running container to play with KERIpy.
