Method Details

init(self, elemLength, lengthLength, fieldName, extType)
(Constructor)

Creates a generic TLS extension.

You'll need to use create or parse methods to create an extension that is actually usable.

Parameters:

server - whether to select ClientHello or ServerHello version for parsing
extType - type of extension encoded as an integer, to be used by subclasses

Overrides: TLSExtension.__init__

(inherited documentation)

repr(self)
(Representation operator)

Output human readable representation of object

Child classes should override this method to support more appropriate string rendering of the extension.

Returns: str
Overrides: TLSExtension.__repr__: (inherited documentation)

setattr(self, name, value)

Set the special field value

Overrides: object.__setattr__

create(self, values)

Set the list to specified values

Parameters:

values (list of int) - list of values to save

Returns: TLSExtension

Overrides: TLSExtension.create

parse(self, parser)

Deserialise extension from on-the-wire data

Parameters:

p - data to be parsed
parser (Parser)

Returns: Extension

Raises:

SyntaxError - when the size of the passed element doesn't match the internal representation

Overrides: TLSExtension.parse

Property Details

extData

a byte array containing the value of the extension as to be written on the wire

Type:: bytearray
