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. ``python -m pyderasn`` has
19 ``--evgen`` mode switcher
20 * Initial experimental CER encoding mode, allowing streaming encoding of
21 the data directly to some writeable object
22 * Ability to use mmap-ed memoryviews to skip files loading to memory
28 * Fixed workability under Python 3.5. Previously only 2.7 and 3.6
35 * Python ``int()``'s accepts even more various non-decimal characters
36 than expected. Make validation fully strict in UTCTime and
37 GeneralizedTime, without relying on ``int()``
43 * UTCTime and GeneralizedTime allowed values to have plus sign in them,
44 passing int() check successfully. Prohibit that incorrect behaviour
45 * UTCTime and GeneralizedTime BER decoding support
46 * Faster UTCTime and GeneralizedTime decoding, and slightly better
48 * Workability under Cython
49 * Explicitly Check that all ObjectIdentifier arcs are non-negative
55 * ``.copy()`` method removed: ``copy.copy()`` is preferred way to copy
57 * Copies made previously with ``.copy()`` lacked ``.defined`` field,
59 * All objects are friendly to ``pickle`` libraries
60 * PrintableString has ``allow_asterisk`` and ``allow_ampersand``
62 * ``.hexencode()``, ``.hexdecode()`` and ``.hexdecod()`` methods
63 appeared, working with hexadecimal encoded data
69 * Convenient ``.decod()`` method, that raises if tail is not empty
70 * Control characters (like newlines) of text fields in pprinted output
72 * Ability to allow asterisk and ampersand characters
73 (``allow_asterisk``, ``allow_ampersand`` kwargs) in PrintableString,
74 that unfortunately could be met in X.509 certificates
80 * PEP-396 compatible module's ``__version__``
86 * Do not shadow underlying DecodeError during decoding of optional
93 * Forbid any later GNU GPL version autousage (project's licence now is
95 * Fix ``defines_by_path`` context option usage example
101 * Fix fallbacked ``colored()`` function workability,
102 if no ``termcolor`` is installed
108 * Fix empty ``--oids`` workability
114 * Ability to specify multiple OID mappings for pprinted output
115 (``oids`` keyword argument is renamed to ``oid_maps``)
121 * Minor decode speed improvements
122 * Much faster UTCTime/GeneralizedTime decoders
123 * Stricter UTCTime/GeneralizedTime DER encoding check: trailing zeroes
125 * Valid DER encoding of GeneralizedTime with microseconds: no trailing
132 * ObjectIdentifier has ``ber_encoded`` set to True, if non-normalized
134 * Preserve BER-related attributes during ``copy()``
140 * Added `COMPLI <https://github.com/YuryStrozhevsky/asn1-test-suite>`__
141 ASN.1:2008 test suite. PyDERASN passes it (except for REAL values),
142 but it is more strict sometimes and aimed to be compliant with X.690-201508
143 * Check for arc values normalization in ObjectIdentifier.
144 Forbid non-normalized in DER encoding
150 * ``ctx`` parameter can be safely used in .decode() and won't be muted
151 * PP nametuple contains reference to the ASN1Obj itself
152 * ``colonize_hex`` function useful for pretty printing
153 * Integer values are also pretty printed in hexadecimal form
159 * All errors are inherited from ASN1Error class
160 * NumericString/PrintableString has ``allowable_chars`` property holding
161 all allowed characters
167 * Fix NumericString: space is allowed character
168 * Strict PrintableString sanitizing
174 * Removed ``lenindef``, ``ber_encoded`` attributes from the Choice --
175 they must be taken from underlying value, as Choice does not have its
177 * Do not yield extra EOC PP for Any, having indefinite length encoding
178 and containing autodecoded DEFINED BY value
184 * ``bered`` attribute, meaning if object has BER-specific encoding, is
185 renamed to ``ber_encoded``
186 * ``bered`` attribute is replace with property showing if any of
187 underlying values are BER-encoded. If value has length indefinite
188 encoded explicit tag, value, if value contains BER-related encoding,
189 or if it contains other objects that are ``bered``, then it is ``bered``
195 * Default value is checked also for Sets, not for Sequences only
196 * **Incompatible** change: defaulted values in Sequence/Set are always
197 strictly checked, unless ``allow_default_values`` context option is
198 set. ``strict_default_existence`` option disappeared
199 * Strict Set/Set Of's values ordering check
205 * Additional encoding validness check: explicit tag must contain exactly
206 one object inside. Throw DecodeError otherwise
207 * ``allow_expl_oob`` context and command-line options allow skipping of
214 * DecodeError's decode paths are separated with ``:``, instead of ``.``,
215 because of colliding with dots in OIDs
216 * Ability to print element decode paths with ``--print-decode-path``
217 command line option (and corresponding keyword argument)
218 * Ability to print tree's branch specified with ``--decode-path-only``
224 * Fix possible uncaught TypeError in Py2 with zero bytes inside the value
225 * Fix SequenceOf/SetOf raising BoundsError instead of DecodeError
231 * Fix uncaught UTCTime/GeneralizedTime decode error when dealing with
232 non ASCII-encoded values
238 * Fix long-standing bug with explicitly tagged objects inside the
239 Choice. If Choice had explicitly tagged value, then its ``.tlvlen``
240 reports the size without taking value's explicit tag in advance
241 * Add ``.fulllen`` and ``.fulloffset`` properties for all objects
247 * SEQUENCE's values are printed with field's name. Previously there was
248 the following output::
250 AlgorithmIdentifier SEQUENCE[OBJECT IDENTIFIER 1.3.14.3.2.26, [UNIV 5] ANY 0500 OPTIONAL]
254 AlgorithmIdentifier SEQUENCE[algorithm: OBJECT IDENTIFIER 1.3.14.3.2.26; parameters: [UNIV 5] ANY 0500 OPTIONAL]
255 * Fixed EOC (Unicode character) repr printing issues under Python2
261 BER's EOC is explicitly shown during pprinting. Following notation::
263 15-2 [0,0,1576]-4 . content: [0] EXPLICIT [UNIV 16] ANY
267 15-2∞ [0,0,1576]∞ . content: [0] EXPLICIT [UNIV 16] ANY
269 1587 [1,1, 0] . content: BER EOC
270 1589 [1,1, 0] . content: EXPLICIT BER EOC
276 * BER decoding support
277 * BitString's ''H notation support
278 * ``termcolor`` package is included in the tarball
284 * Ability to set values during Sequence initialization
290 * Fix TagMismatch exception completeness during Choice and Set decoding.
291 Previously we will loose offset and decode_path information about
292 concrete TagMismatched entity
298 * Strict NumericString's value sanitation
299 * Invalid encoding in string types will raise ``DecodeError`` exception,
300 instead of ``Unicode*Error``
301 * Fixed DecodePathDefBy workability with Python 2.x
307 * Fix nasty BitString decoding bug: it could fail when data follows
308 encoded BitString value. There weren't any problems when BitString is
309 at the end of Sequence
315 * Slightly corrected colours, now visible on white background
321 * Fix bug related to DecodeError showing with DecodePathDefBy entities
322 * Respect ``NO_COLOR`` environment variable
328 * :py:func:`pyderasn.decode_path_defby` is replaced with
329 :py:class:`pyderasn.DecodePathDefBy`
330 * Ability to turn colourized terminal output by calling
331 ``pprint(..., with_colours=True)``. You will need
332 `termcolor package <https://pypi.org/project/termcolor/>`__
338 * Fixed invalid offset calculation when dealing with DEFINED BY objects
345 * BIT STRINGs can also be :ref:`DEFINED BY <definedby>`
346 * Decoding process can be governed with optional :ref:`ctx <ctx>`
347 keyword argument to ``decode()`` method
348 * :ref:`defines_by_path <defines_by_path_ctx>` option is now
349 :ref:`decode context <ctx>` option, not a keyword argument
350 * Ability to do ``strict validation``
351 of defaulted values met in sequence, raising an exception
357 Ability to skip specified number of bytes (``--skip``) in command line
364 * Generic decoder's schema and pretty printer
365 (:py:func:`pyderasn.generic_decoder`) can be used in libraries
366 * Ability to specify :ref:`defines_by_path <defines_by_path_ctx>`
367 during command line invocation
373 Ability to automatically decode :ref:`DEFINED BY <definedby>` fields
380 Removed ``__lt__``/``__eq__`` from base class, as pylint likes it.
386 Full rich comparison operators added.
393 Trivial README addition.
