print("Rand size 255 bytes: {0}\n".format(list(get_random_bytes(255))))
ecc_key = ecc.generate_keypair()
print("Generate NIST-P256 Keypair: {0}\n".format(list(ecc_key.pkey)))

csr = base64.b64encode(request.dump())
print("A new CSR {0}\n".format(csr))
Testing
Tests are written using pytest and require this package to be installed:
$ git clone --recurse-submodules https://github.com/Infineon/python-optiga-trust
...
$ cd python-optiga-trust
$ cd tests
