OEM certificate generation tool

Supports

  • Generating CSR (certificate signing request)
  • Generating OEM intermediate certificate (for testing)
  • Generating OEM leaf certificate chain
  • Erasing file securely
  • Getting CSR/certificate/certificate chain information

Prerequirements

Usage

Run python3 oem_certificate.py --help to see available commands.

The arguments can be partially or fully loaded from a configuration file, for example, if file "location.cfg" is,

  -C=US
  -ST=CA
  -L=Kirkland
  -O=Some Company
  -OU=Some Unit

A command of

  python3 oem_certificate.py generate_csr @location.cfg -CN TestDevice1       \
    --output_csr_file=csr.pem --output_private_key_file=key.der

is equivalent to

  python3 oem_certificate.py generate_csr -CN TestDevice1 -C=US -ST=CA        \
    -L=Kirkland -O='Some Company' -OU='Some Unit' --output_csr_file=csr.pem  \
    --output_private_key_file=key.der.

Note that

  • The arguments in the config file must be one per line;
  • The arguments should not be quoted in the config file.

The script uses a default configuration file 'oem_certificate.cfg', which will be loaded automatically if exists.
