twisted.names.dns.Record_TSIG(tputil.FancyEqMixin, tputil.FancyStrMixin) class documentation

Part of twisted.names.dns (View In Hierarchy)

Implements interfaces: twisted.names.dns.IEncodable, twisted.names.dns.IRecord

A transaction signature, encapsulated in a RR, as described in RFC 2845.

Instance Variable algorithm The name of the signature or MAC algorithm. (type: Name)
Instance Variable timeSigned Signing time, as seconds from the POSIX epoch. (type: int)
Instance Variable fudge Allowable time skew, in seconds. (type: int)
Instance Variable MAC The message digest or signature. (type: bytes)
Instance Variable originalID A message ID. (type: int)
Instance Variable error An error code (extended RCODE) carried in exceptional cases. (type: int)
Instance Variable otherData Other data carried in exceptional cases. (type: bytes)
Method __init__ Undocumented
Method encode Write a representation of this object to the given file object.
Method decode Reconstruct an object from data read from the given file object.
Method __hash__ Undocumented

def encode(self, strio, compDict=None):
from twisted.names.dns.IEncodable

Write a representation of this object to the given file object.

ParametersstrioThe buffer to write to. It must have a tell() method. (type: File-like object)
compDictA mapping of names to byte offsets that have already been written to the buffer, which may be used for compression (see RFC 1035 section 4.1.4). When None, encode without compression. (type: dict of bytes to int r None)
def decode(self, strio, length=None):
from twisted.names.dns.IEncodable

Reconstruct an object from data read from the given file object.

ParametersstrioA seekable buffer from which bytes may be read. (type: File-like object)
lengthThe number of bytes in this RDATA field. Most implementations can ignore this value. Only in the case of records similar to TXT where the total length is in no way encoded in the data is it necessary. (type: int or None)
