`Cryptography` is not a Python stdlib: try: from cryptography import x509 from cryptography.hazmat.primitives import hashes from cryptography.x509.oid import NameOID except ImportError: # pragma: no cover sys.exit("missing dependency: pip install cryptography") Then it goes on with a subprocess for openssl for a case that `cryptography` package does not handle. Why not submit issue with `cryptography` project to get it fixed if it is a problem that needs fixing?
