Validation of Montgomery ECDH with OpenSSL engine using EC mont keys

This example showcases montogomery ECDH between openssl engine and openssl.

Precondition:
    - Inject keys using ``openssl_provisionEC_mont.py``.

optional arguments:
  -h, --help            show this help message and exit

required arguments:
  --key_type KEY_TYPE   Supported key types => ``x25519``, ``x448``

optional arguments:
  --connection_type CONNECTION_TYPE
                        Supported connection types => ``t1oi2c``, ``sci2c``, ``vcom``, ``jrcpv1``, ``jrcpv2``, ``pcsc``. Default: ``t1oi2c``
  --connection_data CONNECTION_DATA
                        Parameter to connect to SE => eg. ``COM3``, ``127.0.0.1:8050``, ``none``. Default: ``none``

Example invocation::

    python openssl_Ecdh_mont.py --key_type x448
    python openssl_Ecdh_mont.py --key_type x25519 --connection_type jrcpv2 --connection_data 127.0.0.1:8050
