mvarcs: Python Mark Verifying Authority Root Certificates

mvarcs provides a collection of Root Certificates for validating the trustworthiness of Mark Certificates such as Verified Mark Certificates (VMC) and Common Mark Certificates (CMC) used in BIMI (Brand Indicators for Message Identification).

Installation

mvarcs is available on PyPI. Simply install it with pip:

python -m pip install mvarcs

Usage

To reference the installed certificate authority (CA) bundle, you can use the built-in function:

importmvarcsmvarcs.where()
# '/usr/local/lib/python3.13/site-packages/mvarcs/mvarcs/cacerts.pem'

Additionally, you can get the contents directly:

importmvarcsmvarcs.contents()
# Issuer: ...# ...# -----END CERTIFICATE-----

Or from the command line:

python -m mvarcs
# /usr/local/lib/python3.13/site-packages/mvarcs/mvarcs/cacert.pem
python -m mvarcs -c
# Issuer: ...# ...# -----END CERTIFICATE-----
