class AcceptableCiphers: (source)

A representation of ciphers that are acceptable for TLS connections.

Class Method	`fromOpenSSLCipherString`	Create a new instance using an OpenSSL cipher string.
Method	`__init__`	Undocumented
Method	`selectCiphers`	Choose which ciphers to allow to be negotiated on a TLS connection.
Instance Variable	`_ciphers`	Undocumented

@classmethod
def fromOpenSSLCipherString(cls, cipherString): (source) ¶

Create a new instance using an OpenSSL cipher string.

Parameters
cipherString:`unicode`	An OpenSSL cipher string that describes what cipher suites are acceptable. See the documentation of OpenSSL or Apache for details.
Returns
`twisted.internet.ssl.AcceptableCiphers`	Instance representing `cipherString`.

def selectCiphers(self, availableCiphers): (source) ¶

from twisted.internet.interfaces.IAcceptableCiphers

Choose which ciphers to allow to be negotiated on a TLS connection.

Parameters
availableCiphers	A `tuple` of `ICipher` which gives the names of all ciphers supported by the TLS implementation in use.
Returns
A `tuple` of `ICipher` which represents the ciphers which may be negotiated on the TLS connection. The result is ordered by preference with more preferred ciphers appearing earlier.
