8 * Fixed invalid behaviour where SET OF allowed multiple objects with the
9 same tag to be successfully decoded
15 * Fixed workability under Python 3.5. Previously only 2.7 and 3.6
22 * Python ``int()``'s accepts even more various non-decimal characters
23 than expected. Make validation fully strict in UTCTime and
24 GeneralizedTime, without relying on ``int()``
30 * UTCTime and GeneralizedTime allowed values to have plus sign in them,
31 passing int() check successfully. Prohibit that incorrect behaviour
32 * UTCTime and GeneralizedTime BER decoding support
33 * Faster UTCTime and GeneralizedTime decoding, and slightly better
35 * Workability under Cython
36 * Explicitly Check that all ObjectIdentifier arcs are non-negative
42 * ``.copy()`` method removed: ``copy.copy()`` is preferred way to copy
44 * Copies made previously with ``.copy()`` lacked ``.defined`` field,
46 * All objects are friendly to ``pickle`` libraries
47 * PrintableString has ``allow_asterisk`` and ``allow_ampersand``
49 * ``.hexencode()``, ``.hexdecode()`` and ``.hexdecod()`` methods
50 appeared, working with hexadecimal encoded data
56 * Convenient ``.decod()`` method, that raises if tail is not empty
57 * Control characters (like newlines) of text fields in pprinted output
59 * Ability to allow asterisk and ampersand characters
60 (``allow_asterisk``, ``allow_ampersand`` kwargs) in PrintableString,
61 that unfortunately could be met in X.509 certificates
67 * PEP-396 compatible module's ``__version__``
73 * Do not shadow underlying DecodeError during decoding of optional
80 * Forbid any later GNU GPL version autousage (project's licence now is
82 * Fix ``defines_by_path`` context option usage example
88 * Fix fallbacked ``colored()`` function workability,
89 if no ``termcolor`` is installed
95 * Fix empty ``--oids`` workability
101 * Ability to specify multiple OID mappings for pprinted output
102 (``oids`` keyword argument is renamed to ``oid_maps``)
108 * Minor decode speed improvements
109 * Much faster UTCTime/GeneralizedTime decoders
110 * Stricter UTCTime/GeneralizedTime DER encoding check: trailing zeroes
112 * Valid DER encoding of GeneralizedTime with microseconds: no trailing
119 * ObjectIdentifier has ``ber_encoded`` set to True, if non-normalized
121 * Preserve BER-related attributes during ``copy()``
127 * Added `COMPLI <https://github.com/YuryStrozhevsky/asn1-test-suite>`__
128 ASN.1:2008 test suite. PyDERASN passes it (except for REAL values),
129 but it is more strict sometimes and aimed to be compliant with X.690-201508
130 * Check for arc values normalization in ObjectIdentifier.
131 Forbid non-normalized in DER encoding
137 * ``ctx`` parameter can be safely used in .decode() and won't be muted
138 * PP nametuple contains reference to the ASN1Obj itself
139 * ``colonize_hex`` function useful for pretty printing
140 * Integer values are also pretty printed in hexadecimal form
146 * All errors are inherited from ASN1Error class
147 * NumericString/PrintableString has ``allowable_chars`` property holding
148 all allowed characters
154 * Fix NumericString: space is allowed character
155 * Strict PrintableString sanitizing
161 * Removed ``lenindef``, ``ber_encoded`` attributes from the Choice --
162 they must be taken from underlying value, as Choice does not have its
164 * Do not yield extra EOC PP for Any, having indefinite length encoding
165 and containing autodecoded DEFINED BY value
171 * ``bered`` attribute, meaning if object has BER-specific encoding, is
172 renamed to ``ber_encoded``
173 * ``bered`` attribute is replace with property showing if any of
174 underlying values are BER-encoded. If value has length indefinite
175 encoded explicit tag, value, if value contains BER-related encoding,
176 or if it contains other objects that are ``bered``, then it is ``bered``
182 * Default value is checked also for Sets, not for Sequences only
183 * **Incompatible** change: defaulted values in Sequence/Set are always
184 strictly checked, unless ``allow_default_values`` context option is
185 set. ``strict_default_existence`` option disappeared
186 * Strict Set/Set Of's values ordering check
192 * Additional encoding validness check: explicit tag must contain exactly
193 one object inside. Throw DecodeError otherwise
194 * ``allow_expl_oob`` context and command-line options allow skipping of
201 * DecodeError's decode paths are separated with ``:``, instead of ``.``,
202 because of colliding with dots in OIDs
203 * Ability to print element decode paths with ``--print-decode-path``
204 command line option (and corresponding keyword argument)
205 * Ability to print tree's branch specified with ``--decode-path-only``
211 * Fix possible uncaught TypeError in Py2 with zero bytes inside the value
212 * Fix SequenceOf/SetOf raising BoundsError instead of DecodeError
218 * Fix uncaught UTCTime/GeneralizedTime decode error when dealing with
219 non ASCII-encoded values
225 * Fix long-standing bug with explicitly tagged objects inside the
226 Choice. If Choice had explicitly tagged value, then its ``.tlvlen``
227 reports the size without taking value's explicit tag in advance
228 * Add ``.fulllen`` and ``.fulloffset`` properties for all objects
234 * SEQUENCE's values are printed with field's name. Previously there was
235 the following output::
237 AlgorithmIdentifier SEQUENCE[OBJECT IDENTIFIER 1.3.14.3.2.26, [UNIV 5] ANY 0500 OPTIONAL]
241 AlgorithmIdentifier SEQUENCE[algorithm: OBJECT IDENTIFIER 1.3.14.3.2.26; parameters: [UNIV 5] ANY 0500 OPTIONAL]
242 * Fixed EOC (Unicode character) repr printing issues under Python2
248 BER's EOC is explicitly shown during pprinting. Following notation::
250 15-2 [0,0,1576]-4 . content: [0] EXPLICIT [UNIV 16] ANY
254 15-2∞ [0,0,1576]∞ . content: [0] EXPLICIT [UNIV 16] ANY
256 1587 [1,1, 0] . content: BER EOC
257 1589 [1,1, 0] . content: EXPLICIT BER EOC
263 * BER decoding support
264 * BitString's ''H notation support
265 * ``termcolor`` package is included in the tarball
271 * Ability to set values during Sequence initialization
277 * Fix TagMismatch exception completeness during Choice and Set decoding.
278 Previously we will loose offset and decode_path information about
279 concrete TagMismatched entity
285 * Strict NumericString's value sanitation
286 * Invalid encoding in string types will raise ``DecodeError`` exception,
287 instead of ``Unicode*Error``
288 * Fixed DecodePathDefBy workability with Python 2.x
294 * Fix nasty BitString decoding bug: it could fail when data follows
295 encoded BitString value. There weren't any problems when BitString is
296 at the end of Sequence
302 * Slightly corrected colours, now visible on white background
308 * Fix bug related to DecodeError showing with DecodePathDefBy entities
309 * Respect ``NO_COLOR`` environment variable
315 * :py:func:`pyderasn.decode_path_defby` is replaced with
316 :py:class:`pyderasn.DecodePathDefBy`
317 * Ability to turn colourized terminal output by calling
318 ``pprint(..., with_colours=True)``. You will need
319 `termcolor package <https://pypi.org/project/termcolor/>`__
325 * Fixed invalid offset calculation when dealing with DEFINED BY objects
332 * BIT STRINGs can also be :ref:`DEFINED BY <definedby>`
333 * Decoding process can be governed with optional :ref:`ctx <ctx>`
334 keyword argument to ``decode()`` method
335 * :ref:`defines_by_path <defines_by_path_ctx>` option is now
336 :ref:`decode context <ctx>` option, not a keyword argument
337 * Ability to do ``strict validation``
338 of defaulted values met in sequence, raising an exception
344 Ability to skip specified number of bytes (``--skip``) in command line
351 * Generic decoder's schema and pretty printer
352 (:py:func:`pyderasn.generic_decoder`) can be used in libraries
353 * Ability to specify :ref:`defines_by_path <defines_by_path_ctx>`
354 during command line invocation
360 Ability to automatically decode :ref:`DEFINED BY <definedby>` fields
367 Removed ``__lt__``/``__eq__`` from base class, as pylint likes it.
373 Full rich comparison operators added.
380 Trivial README addition.
