def getPublicKeyString(filename=None, line=0, data=''): (source)

Return a public key string suitable for being sent over the wire. Takes a filename or data of a public key. Currently handles OpenSSH and LSH keys.

This function has been deprecated since Twisted Conch 0.9. Use Key.fromString() instead.

Parameters	filename	(type: `str` )
	line	(type: `int` )
	data	(type: `str` )
Returns	(type: `str` )

def makePublicKeyString(obj, comment='', kind='openssh'): (source)

Return an public key given a Crypto.PublicKey.pubkey.pubkey object. kind is one of ('openssh', 'lsh')

This function is deprecated since Twisted Conch 0.9. Instead use Key(obj).toString().

Parameters	obj	(type: `Crypto.PublicKey.pubkey.pubkey` )
	comment	(type: `str` )
	kind	(type: `str` )
Returns	(type: `str` )

def getPublicKeyObject(data): (source)

Return a Crypto.PublicKey.pubkey.pubkey corresponding to the SSHv2 public key data. data is in the over-the-wire public key format.

This function is deprecated since Twisted Conch 0.9. Instead, use Key.fromString().

Parameters	data	(type: `str` )
Returns	(type: `Crypto.PublicKey.pubkey.pubkey` )

def getPrivateKeyObject(filename=None, data='', passphrase=''): (source)

Return a Crypto.PublicKey.pubkey.pubkey object corresponding to the private key file/data. If the private key is encrypted, passphrase must be specified, other wise a BadKeyError will be raised.

This method is deprecated since Twisted Conch 0.9. Instead, use the fromString or fromFile classmethods of Key.

Parameters	filename	(type: `str` )
	data	(type: `str` )
	passphrase	(type: `str` )
Returns	(type: `Crypto.PublicKey.pubkey.pubkey` )
Raises	BadKeyError	if the key is invalid or a passphrase is not specified

def makePrivateKeyString(obj, passphrase=None, kind='openssh'): (source)

Return an OpenSSH-style private key for a Crypto.PublicKey.pubkey.pubkey object. If passphrase is given, encrypt the private key with it. kind is one of ('openssh', 'lsh', 'agentv3')

This function is deprecated since Twisted Conch 0.9. Instead use Key(obj).toString().

Parameters	obj	(type: `Crypto.PublicKey.pubkey.pubkey` )
	passphrase	(type: `str`/`None` )
	kind	(type: `str` )
Returns	(type: `str` )

def objectType(obj): (source)

Return the SSH key type corresponding to a Crypto.PublicKey.pubkey.pubkey object.

Parameters	obj	(type: `Crypto.PublicKey.pubkey.pubkey` )
Returns	(type: `str` )

def signData(obj, data): (source)

Sign the data with the given Crypto.PublicKey.pubkey.pubkey object.

This method is deprecated since Twisted Conch 0.9. Instead use Key().sign().

Parameters	obj	(type: `Crypto.PublicKey.pubkey.pubkey` )
	data	(type: `str` )
Returns	(type: `str` )

def verifySignature(obj, sig, data): (source)

Verify that the signature for the data is valid.

This method is deprecated since Twisted Conch 0.9. Use Key().verify().

Parameters	obj	(type: `Crypto.PublicKey.pubkey.pubkey` )
	sig	(type: `str` )
	data	(type: `str` )
Returns	(type: `bool` )

def printKey(obj): (source)

Pretty print a Crypto.PublicKey.pubkey.pubkey object.

This function is deprecated since Twisted Conch 0.9. Use repr(Key()).

Parameters obj (type: Crypto.PublicKey.pubkey.pubkey )
