Create a new instance of this public key type. If ``msg`` is given,
the key's public part(s) will be filled in from the message. If
``data`` is given, the key's public part(s) will be filled in from
the string.

Compare this key to another. Returns 0 if this key is equivalent to

Create a key object by reading a private key file. If the private
key is encrypted and ``password`` is not ``None``, the given password
will be used to decrypt the key (otherwise `.PasswordRequiredException`
is thrown). Through the magic of Python, this factory method will
exist in all subclasses of PKey (such as `.RSAKey` or `.DSSKey`), but
is useless on the abstract PKey class.

Read an SSH2-format private key file, looking for a string of the type
``"BEGIN xxx PRIVATE KEY"`` for some ``xxx``, base64-decode the text we
find, and return it as a string. If the private key is encrypted and

Write an SSH2-format private key file in a form that can be read by
paramiko or openssh. If no password is given, the key is written in
a trivially-encoded format (base64) which is completely insecure. If
a password is given, DES-EDE3-CBC is used.

Perform message type-checking & optional certificate loading.
This includes fast-forwarding cert ``msg`` objects past the nonce, so
that the subsequent fields are the key numbers; thus the caller may
expect to treat the message as key material afterwards either way.
The obtained key type is returned for classes which need to know what
it was (e.g. ECDSA.)

Supplement the private key contents with data loaded from an OpenSSH
public key (``.pub``) or certificate (``-cert.pub``) file, a string
containing such a file, or a `.Message` object.
The .pub contents adds no real value, since the private key
file includes sufficient information to derive the public
key info. For certificates, however, this can be used on
the client side to offer authentication requests to the server
based on certificate instead of raw public key.
See:
https://github.com/openssh/openssh-portable/blob/master/PROTOCOL.certkeys
Note: very little effort is made to validate the certificate contents,
that is for the server to decide if it is good enough to authenticate
successfully.

OpenSSH plain public key or OpenSSH signed public key (certificate).
Tries to be as dumb as possible and barely cares about specific
per-key-type data.
..note::
Most of the time you'll want to call `from_file`, `from_string` or
`from_message` for useful instantiation, the main constructor is
basically "I should be using ``attrs`` for this."
