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 hashclass: class from L{Crypto.Hash} that can be used as a secure
hashing function (like C{MD5} or C{SHA}).
@type hashclass: L{Crypto.Hash}
@param salt: data to salt the hash with.
@type salt: string
@param key: human-entered password or passphrase.
@type key: string
@param nbytes: number of bytes to generate.
@type nbytes: int
@return: key data
@rtype: string

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