Python library for signing x509 using keys in an pkcs11 device such as a HSM

Project description

python_x509_pkcs11

Seamless signing x509 using PKCS11 device for key storage

Currently supports

  • Creating a root CA and generating its RSA key in the PKCS11 device
  • Using the key in the PKCS11 device to sign certificates (or Intermediate CAs)
  • Creating CRLs with the PKCS11 device key
  • Store multiple keys in the PKCS11 device enabling a full PKI infrastructure
  • 'Advanced' handling of fragile persistent PKCS11 sessions, including recreating the session if PKCS11 operation timeout

This package is pretty much a wrapper around python-pkcs11 and asn1crypto

Setup

# Install libs and add your user to the softhsm group

if awk -F= '/^NAME/{print $2}' /etc/os-release | grep -i "debian\|ubuntu"
then
    # Ubuntu / Debian
    sudo apt-get install python3-dev python3-pip softhsm2
    sudo usermod -a -G softhsm $USER
else
    # Redhat / Centos / Fedora
    sudo dnf install python3-devel python3-pip softhsm gcc 
    sudo usermod -a -G ods $USER
fi

# Or reboot, just make sure your shell now has the new group	
echo "logout and login again now"

# Install this package
pip3 install python_x509_pkcs11

# export env values the code will use
if awk -F= '/^NAME/{print $2}' /etc/os-release | grep -i "debian\|ubuntu"
then
    export PKCS11_MODULE="/usr/lib/softhsm/libsofthsm2.so"
else
    export PKCS11_MODULE="/usr/lib64/softhsm/libsofthsm.so"
fi
export PKCS11_PIN="1234"
export PKCS11_TOKEN="my_test_token_1"

# Initialize the token
softhsm2-util --init-token --slot 0 --label $PKCS11_TOKEN --pin $PKCS11_PIN --so-pin $PKCS11_PIN

Usage

Look at the documentation for quick examples to begin.

The tests are also a good starting point

Here is the basic, create a root CA and then use its key in the PKCS11 device to sign a csr

# export env values the code will use
if awk -F= '/^NAME/{print $2}' /etc/os-release | grep -i "debian\|ubuntu"
then
    export PKCS11_MODULE="/usr/lib/softhsm/libsofthsm2.so"
else
    export PKCS11_MODULE="/usr/lib64/softhsm/libsofthsm.so"
fi
export PKCS11_PIN="1234"
export PKCS11_TOKEN="my_test_token_1"


# Delete the previous token if exists
softhsm2-util --delete-token --token $PKCS11_TOKEN

# Initialize a new fresh PKCS11 token
softhsm2-util --init-token --slot 0 --label $PKCS11_TOKEN --pin $PKCS11_PIN --so-pin $PKCS11_PIN
