The key generation example in this repo is not working any more

[FoamyGuy]

It raises this exception:

ValueError: No PEM start marker "b'-----BEGIN RSA PRIVATE KEY-----'" found

The private key that was generated begins with -----BEGIN PRIVATE KEY-----, note the lack of "RSA". I'm guessing that my version of openssl is newer than what this example or the library it uses were written for.
