Given a password, passphrase, or other human-source key, scramble it
through a secure hash into some keyworthy bytes. This specific algorithm
is used for encrypting/decrypting private key files.
:param function hash_alg: A function which creates a new hash object, such
as ``hashlib.sha256``.
:param salt: data to salt the hash with.
:type salt: byte string
:param str key: human-entered password or passphrase.
:param int nbytes: number of bytes to generate.
:return: Key data `str`

Read a file of known SSH host keys, in the format used by openssh, and
return a compound dict of ``hostname -> keytype ->`` `PKey
<paramiko.pkey.PKey>`. The hostname may be an IP address or DNS name. The
keytype will be either ``"ssh-rsa"`` or ``"ssh-dss"``.
This type of file unfortunately doesn't exist on Windows, but on posix,
it will usually be stored in ``os.path.expanduser("~/.ssh/known_hosts")``.
Since 1.5.3, this is just a wrapper around `.HostKeys`.
:param str filename: name of the file to read host keys from
:return:
nested dict of `.PKey` objects, indexed by hostname and then keytype
