ASN.1 tools for Python

Whenever data structures are described in some machine and programming
language independent and unambiguous way, such specification is called
abstract syntax, by contrast with machine/language specific methods,
which are called 'concrete' or 'transfer' syntaxes.

Abstract syntaxes appear useful in networking as a tool for engineering
protocols in a clear and portable way. Moreover, once a protocol is
described in some abstract language, protocol parsers and builders
could be automatically generated for various computing
architectures/programming languages, thus saving engineers from
implementing low-level transport details by hand.

Abstract Syntax Notation One (ASN.1) is a set of ITU standards
defining particular implementation of abstract data description
language accompanied by a collection of transfer encoding methods.
Perhaps the most widely used among these data serialization methods
is Basic Encoding Rules (BER) together with its derivatives (DER and
CER), while Packed Encoding Rules (PER) aims at most compact data
representation whilst in the wire.

Log message:
py-asn1: updated to 0.4.4

Revision 0.4.4:
- Fixed native encoder type map to include all ASN.1 types
  rather than just ambiguous ones
- Fixed crash in .prettyPrint of Sequence and Set occurring
  at OPTIONAL components

Log message:
py-asn1: updated to 0.4.3

0.4.3:
Copyright notice extended to the year 2018
Fixed GeneralizedTime.asDateTime to perform milliseconds conversion correctly

Log message:
py-asn1: updated to 0.4.2

Revision 0.4.2:
---------------
- Fixed explicit tag splitting in chunked encoding mode at
  OctetString and BitString encoders

Revision 0.4.1:
---------------
- ANY DEFINED BY clause support implemented
- Encoders refactored to take either a value (as ASN.1 object)
  or a Python value plus ASN.1 schema
- BitString decoder optimised for better performance when running on
  constructed encoding
- Constructed types' .getComponentBy*() methods accept the default
  parameter to return instead if schema object is to be returned
- Constructed types' .getComponentBy*() methods accept the instantiate
  parameter to disable automatic inner component instantiation
- The ASN.1 types' __repr__ implementation reworked for better readability
  at the cost of not being eval-compliant
- Most ASN.1 types' __str__ magic methods (except for OctetString and
  character types) reworked to call .prettyPrint() rather than
  .prettyPrint calling __str__ as it was before. The intention is
  to eventually deprecate .prettyPrint() in favor of str().
  The other related change is that str() of enumerations and boolean
  types will return string label instead of number.
- Fixed Choice.clear() to fully reset internal state of the object
- Sphinx documentation rearranged, simplified and reworded
- The isValue singleton is now the only way to indicate ASN.1 schema
  as opposed to ASN.1 schema instance. The legacy None initializer
  support has been removed.
- Changed Null object initialization behaviour: previous default
  value ('') is not set anymore. Thus Null() call produces a
  ASN.1 schema object, while Null('') - value object.
- Migrated all docs and references from SourceForge
- Imports PEP8'ed
- Fixed ASN.1 encoder not to omit empty substrate produced for inner
  component if the inner component belongs to the simple class (as
  opposed to constructed class)
- Fixed CER/DER encoders to respect tagged CHOICE when ordering
  SET components
- Fixed ASN.1 types not to interfere with the Pickle protocol
- Fixed Sequence/SequenceOf types decoding heuristics in schema-less
  decoding mode

Log message:
py-asn1: update to 0.3.7

Revision 0.3.7:
Fixed ASN.1 time types pickling/deepcopy'ing
   2017-09-30 17:12:30 by Adam Ciarcinski | Files touched by this commit (2) | Package updated
Log message:
py-asn1: update to 0.3.6

Revision 0.3.6:
* End-of-octets encoding optimized at ASN.1 encoders
* The __getitem__/__setitem__ behavior of Set/Sequence and SetOf/SequenceOf \ 
objects aligned with the canonical Mapping and Sequence protocols in part
* Fixed crash in ASN.1 encoder when encoding an explicitly tagged component of a \ 
Sequence

Log message:
py-asn1: update to 0.3.5

Revision 0.3.5:
Codecs signatures unified and pass the options kwargs through the call chain
Explicit tag encoding optimized to avoid unnecessary copying
End-of-octets sentinel encoding optimized
Refactored ASN.1 codecs properties to silently enforce proper length and chunk \ 
size encoding modes
Fixed DER encoder to always produce primitive encoding
Fixed crash at SequenceOf native decoder
Fixed Real.prettyPrint() to fail gracefully on overflow
Fixed a couple of crashes when debug mode is enabled
   2017-09-08 09:28:31 by Adam Ciarcinski | Files touched by this commit (2)
Log message:
Revision 0.3.4:
- Fixed Native encoder to handle SEQUENCE/SET objects without
  the componentType property
- Added missing component-less SEQUENCE/SET objects dict duck-typing support
- Fixed unnecessary duplicate tags detection at NamesType.tagMap
- Fixed crash at SEQUENCE and SEQUENCE OF CER encoder when running
  in schemaless mode
- Fixed Character types instantiation from OctetString type -- double
  unicode decoding may have scrambled the data
