8 * Fixed invalid behaviour where SET OF allowed multiple objects with the
9 same tag to be successfully decoded
10 * Fixed possibly invalid SET DER encoding where objects were not sorted
11 by tag, but by encoded representation
12 * ``Any`` does not allow empty data value now. Now it checks if it has
14 * ``Any`` allows an ordinary ``Obj`` storing, without its forceful
15 encoded representation storage
16 * Initial support for so called ``evgen_mode``: event generation mode,
17 where no in-memory objects storing happens, giving ability to process
18 ASN.1 data without fully parsing it first
19 * Initial experimental CER encoding mode, allowing streaming encoding of
20 the data directly to some writeable object
26 * Fixed workability under Python 3.5. Previously only 2.7 and 3.6
33 * Python ``int()``'s accepts even more various non-decimal characters
34 than expected. Make validation fully strict in UTCTime and
35 GeneralizedTime, without relying on ``int()``
41 * UTCTime and GeneralizedTime allowed values to have plus sign in them,
42 passing int() check successfully. Prohibit that incorrect behaviour
43 * UTCTime and GeneralizedTime BER decoding support
44 * Faster UTCTime and GeneralizedTime decoding, and slightly better
46 * Workability under Cython
47 * Explicitly Check that all ObjectIdentifier arcs are non-negative
53 * ``.copy()`` method removed: ``copy.copy()`` is preferred way to copy
55 * Copies made previously with ``.copy()`` lacked ``.defined`` field,
57 * All objects are friendly to ``pickle`` libraries
58 * PrintableString has ``allow_asterisk`` and ``allow_ampersand``
60 * ``.hexencode()``, ``.hexdecode()`` and ``.hexdecod()`` methods
61 appeared, working with hexadecimal encoded data
67 * Convenient ``.decod()`` method, that raises if tail is not empty
68 * Control characters (like newlines) of text fields in pprinted output
70 * Ability to allow asterisk and ampersand characters
71 (``allow_asterisk``, ``allow_ampersand`` kwargs) in PrintableString,
72 that unfortunately could be met in X.509 certificates
78 * PEP-396 compatible module's ``__version__``
84 * Do not shadow underlying DecodeError during decoding of optional
91 * Forbid any later GNU GPL version autousage (project's licence now is
93 * Fix ``defines_by_path`` context option usage example
99 * Fix fallbacked ``colored()`` function workability,
100 if no ``termcolor`` is installed
106 * Fix empty ``--oids`` workability
112 * Ability to specify multiple OID mappings for pprinted output
113 (``oids`` keyword argument is renamed to ``oid_maps``)
119 * Minor decode speed improvements
120 * Much faster UTCTime/GeneralizedTime decoders
121 * Stricter UTCTime/GeneralizedTime DER encoding check: trailing zeroes
123 * Valid DER encoding of GeneralizedTime with microseconds: no trailing
130 * ObjectIdentifier has ``ber_encoded`` set to True, if non-normalized
132 * Preserve BER-related attributes during ``copy()``
138 * Added `COMPLI <https://github.com/YuryStrozhevsky/asn1-test-suite>`__
139 ASN.1:2008 test suite. PyDERASN passes it (except for REAL values),
140 but it is more strict sometimes and aimed to be compliant with X.690-201508
141 * Check for arc values normalization in ObjectIdentifier.
142 Forbid non-normalized in DER encoding
148 * ``ctx`` parameter can be safely used in .decode() and won't be muted
149 * PP nametuple contains reference to the ASN1Obj itself
150 * ``colonize_hex`` function useful for pretty printing
151 * Integer values are also pretty printed in hexadecimal form
157 * All errors are inherited from ASN1Error class
158 * NumericString/PrintableString has ``allowable_chars`` property holding
159 all allowed characters
165 * Fix NumericString: space is allowed character
166 * Strict PrintableString sanitizing
172 * Removed ``lenindef``, ``ber_encoded`` attributes from the Choice --
173 they must be taken from underlying value, as Choice does not have its
175 * Do not yield extra EOC PP for Any, having indefinite length encoding
176 and containing autodecoded DEFINED BY value
182 * ``bered`` attribute, meaning if object has BER-specific encoding, is
183 renamed to ``ber_encoded``
184 * ``bered`` attribute is replace with property showing if any of
185 underlying values are BER-encoded. If value has length indefinite
186 encoded explicit tag, value, if value contains BER-related encoding,
187 or if it contains other objects that are ``bered``, then it is ``bered``
193 * Default value is checked also for Sets, not for Sequences only
194 * **Incompatible** change: defaulted values in Sequence/Set are always
195 strictly checked, unless ``allow_default_values`` context option is
196 set. ``strict_default_existence`` option disappeared
197 * Strict Set/Set Of's values ordering check
203 * Additional encoding validness check: explicit tag must contain exactly
204 one object inside. Throw DecodeError otherwise
205 * ``allow_expl_oob`` context and command-line options allow skipping of
212 * DecodeError's decode paths are separated with ``:``, instead of ``.``,
213 because of colliding with dots in OIDs
214 * Ability to print element decode paths with ``--print-decode-path``
215 command line option (and corresponding keyword argument)
216 * Ability to print tree's branch specified with ``--decode-path-only``
222 * Fix possible uncaught TypeError in Py2 with zero bytes inside the value
223 * Fix SequenceOf/SetOf raising BoundsError instead of DecodeError
229 * Fix uncaught UTCTime/GeneralizedTime decode error when dealing with
230 non ASCII-encoded values
236 * Fix long-standing bug with explicitly tagged objects inside the
237 Choice. If Choice had explicitly tagged value, then its ``.tlvlen``
238 reports the size without taking value's explicit tag in advance
239 * Add ``.fulllen`` and ``.fulloffset`` properties for all objects
245 * SEQUENCE's values are printed with field's name. Previously there was
246 the following output::
248 AlgorithmIdentifier SEQUENCE[OBJECT IDENTIFIER 1.3.14.3.2.26, [UNIV 5] ANY 0500 OPTIONAL]
252 AlgorithmIdentifier SEQUENCE[algorithm: OBJECT IDENTIFIER 1.3.14.3.2.26; parameters: [UNIV 5] ANY 0500 OPTIONAL]
253 * Fixed EOC (Unicode character) repr printing issues under Python2
259 BER's EOC is explicitly shown during pprinting. Following notation::
261 15-2 [0,0,1576]-4 . content: [0] EXPLICIT [UNIV 16] ANY
265 15-2∞ [0,0,1576]∞ . content: [0] EXPLICIT [UNIV 16] ANY
267 1587 [1,1, 0] . content: BER EOC
268 1589 [1,1, 0] . content: EXPLICIT BER EOC
274 * BER decoding support
275 * BitString's ''H notation support
276 * ``termcolor`` package is included in the tarball
282 * Ability to set values during Sequence initialization
288 * Fix TagMismatch exception completeness during Choice and Set decoding.
289 Previously we will loose offset and decode_path information about
290 concrete TagMismatched entity
296 * Strict NumericString's value sanitation
297 * Invalid encoding in string types will raise ``DecodeError`` exception,
298 instead of ``Unicode*Error``
299 * Fixed DecodePathDefBy workability with Python 2.x
305 * Fix nasty BitString decoding bug: it could fail when data follows
306 encoded BitString value. There weren't any problems when BitString is
307 at the end of Sequence
313 * Slightly corrected colours, now visible on white background
319 * Fix bug related to DecodeError showing with DecodePathDefBy entities
320 * Respect ``NO_COLOR`` environment variable
326 * :py:func:`pyderasn.decode_path_defby` is replaced with
327 :py:class:`pyderasn.DecodePathDefBy`
328 * Ability to turn colourized terminal output by calling
329 ``pprint(..., with_colours=True)``. You will need
330 `termcolor package <https://pypi.org/project/termcolor/>`__
336 * Fixed invalid offset calculation when dealing with DEFINED BY objects
343 * BIT STRINGs can also be :ref:`DEFINED BY <definedby>`
344 * Decoding process can be governed with optional :ref:`ctx <ctx>`
345 keyword argument to ``decode()`` method
346 * :ref:`defines_by_path <defines_by_path_ctx>` option is now
347 :ref:`decode context <ctx>` option, not a keyword argument
348 * Ability to do ``strict validation``
349 of defaulted values met in sequence, raising an exception
355 Ability to skip specified number of bytes (``--skip``) in command line
362 * Generic decoder's schema and pretty printer
363 (:py:func:`pyderasn.generic_decoder`) can be used in libraries
364 * Ability to specify :ref:`defines_by_path <defines_by_path_ctx>`
365 during command line invocation
371 Ability to automatically decode :ref:`DEFINED BY <definedby>` fields
378 Removed ``__lt__``/``__eq__`` from base class, as pylint likes it.
384 Full rich comparison operators added.
391 Trivial README addition.
