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 valid
19 * Fixed workability under Python 3.5. Previously only 2.7 and 3.6
26 * Python ``int()``'s accepts even more various non-decimal characters
27 than expected. Make validation fully strict in UTCTime and
28 GeneralizedTime, without relying on ``int()``
34 * UTCTime and GeneralizedTime allowed values to have plus sign in them,
35 passing int() check successfully. Prohibit that incorrect behaviour
36 * UTCTime and GeneralizedTime BER decoding support
37 * Faster UTCTime and GeneralizedTime decoding, and slightly better
39 * Workability under Cython
40 * Explicitly Check that all ObjectIdentifier arcs are non-negative
46 * ``.copy()`` method removed: ``copy.copy()`` is preferred way to copy
48 * Copies made previously with ``.copy()`` lacked ``.defined`` field,
50 * All objects are friendly to ``pickle`` libraries
51 * PrintableString has ``allow_asterisk`` and ``allow_ampersand``
53 * ``.hexencode()``, ``.hexdecode()`` and ``.hexdecod()`` methods
54 appeared, working with hexadecimal encoded data
60 * Convenient ``.decod()`` method, that raises if tail is not empty
61 * Control characters (like newlines) of text fields in pprinted output
63 * Ability to allow asterisk and ampersand characters
64 (``allow_asterisk``, ``allow_ampersand`` kwargs) in PrintableString,
65 that unfortunately could be met in X.509 certificates
71 * PEP-396 compatible module's ``__version__``
77 * Do not shadow underlying DecodeError during decoding of optional
84 * Forbid any later GNU GPL version autousage (project's licence now is
86 * Fix ``defines_by_path`` context option usage example
92 * Fix fallbacked ``colored()`` function workability,
93 if no ``termcolor`` is installed
99 * Fix empty ``--oids`` workability
105 * Ability to specify multiple OID mappings for pprinted output
106 (``oids`` keyword argument is renamed to ``oid_maps``)
112 * Minor decode speed improvements
113 * Much faster UTCTime/GeneralizedTime decoders
114 * Stricter UTCTime/GeneralizedTime DER encoding check: trailing zeroes
116 * Valid DER encoding of GeneralizedTime with microseconds: no trailing
123 * ObjectIdentifier has ``ber_encoded`` set to True, if non-normalized
125 * Preserve BER-related attributes during ``copy()``
131 * Added `COMPLI <https://github.com/YuryStrozhevsky/asn1-test-suite>`__
132 ASN.1:2008 test suite. PyDERASN passes it (except for REAL values),
133 but it is more strict sometimes and aimed to be compliant with X.690-201508
134 * Check for arc values normalization in ObjectIdentifier.
135 Forbid non-normalized in DER encoding
141 * ``ctx`` parameter can be safely used in .decode() and won't be muted
142 * PP nametuple contains reference to the ASN1Obj itself
143 * ``colonize_hex`` function useful for pretty printing
144 * Integer values are also pretty printed in hexadecimal form
150 * All errors are inherited from ASN1Error class
151 * NumericString/PrintableString has ``allowable_chars`` property holding
152 all allowed characters
158 * Fix NumericString: space is allowed character
159 * Strict PrintableString sanitizing
165 * Removed ``lenindef``, ``ber_encoded`` attributes from the Choice --
166 they must be taken from underlying value, as Choice does not have its
168 * Do not yield extra EOC PP for Any, having indefinite length encoding
169 and containing autodecoded DEFINED BY value
175 * ``bered`` attribute, meaning if object has BER-specific encoding, is
176 renamed to ``ber_encoded``
177 * ``bered`` attribute is replace with property showing if any of
178 underlying values are BER-encoded. If value has length indefinite
179 encoded explicit tag, value, if value contains BER-related encoding,
180 or if it contains other objects that are ``bered``, then it is ``bered``
186 * Default value is checked also for Sets, not for Sequences only
187 * **Incompatible** change: defaulted values in Sequence/Set are always
188 strictly checked, unless ``allow_default_values`` context option is
189 set. ``strict_default_existence`` option disappeared
190 * Strict Set/Set Of's values ordering check
196 * Additional encoding validness check: explicit tag must contain exactly
197 one object inside. Throw DecodeError otherwise
198 * ``allow_expl_oob`` context and command-line options allow skipping of
205 * DecodeError's decode paths are separated with ``:``, instead of ``.``,
206 because of colliding with dots in OIDs
207 * Ability to print element decode paths with ``--print-decode-path``
208 command line option (and corresponding keyword argument)
209 * Ability to print tree's branch specified with ``--decode-path-only``
215 * Fix possible uncaught TypeError in Py2 with zero bytes inside the value
216 * Fix SequenceOf/SetOf raising BoundsError instead of DecodeError
222 * Fix uncaught UTCTime/GeneralizedTime decode error when dealing with
223 non ASCII-encoded values
229 * Fix long-standing bug with explicitly tagged objects inside the
230 Choice. If Choice had explicitly tagged value, then its ``.tlvlen``
231 reports the size without taking value's explicit tag in advance
232 * Add ``.fulllen`` and ``.fulloffset`` properties for all objects
238 * SEQUENCE's values are printed with field's name. Previously there was
239 the following output::
241 AlgorithmIdentifier SEQUENCE[OBJECT IDENTIFIER 1.3.14.3.2.26, [UNIV 5] ANY 0500 OPTIONAL]
245 AlgorithmIdentifier SEQUENCE[algorithm: OBJECT IDENTIFIER 1.3.14.3.2.26; parameters: [UNIV 5] ANY 0500 OPTIONAL]
246 * Fixed EOC (Unicode character) repr printing issues under Python2
252 BER's EOC is explicitly shown during pprinting. Following notation::
254 15-2 [0,0,1576]-4 . content: [0] EXPLICIT [UNIV 16] ANY
258 15-2∞ [0,0,1576]∞ . content: [0] EXPLICIT [UNIV 16] ANY
260 1587 [1,1, 0] . content: BER EOC
261 1589 [1,1, 0] . content: EXPLICIT BER EOC
267 * BER decoding support
268 * BitString's ''H notation support
269 * ``termcolor`` package is included in the tarball
275 * Ability to set values during Sequence initialization
281 * Fix TagMismatch exception completeness during Choice and Set decoding.
282 Previously we will loose offset and decode_path information about
283 concrete TagMismatched entity
289 * Strict NumericString's value sanitation
290 * Invalid encoding in string types will raise ``DecodeError`` exception,
291 instead of ``Unicode*Error``
292 * Fixed DecodePathDefBy workability with Python 2.x
298 * Fix nasty BitString decoding bug: it could fail when data follows
299 encoded BitString value. There weren't any problems when BitString is
300 at the end of Sequence
306 * Slightly corrected colours, now visible on white background
312 * Fix bug related to DecodeError showing with DecodePathDefBy entities
313 * Respect ``NO_COLOR`` environment variable
319 * :py:func:`pyderasn.decode_path_defby` is replaced with
320 :py:class:`pyderasn.DecodePathDefBy`
321 * Ability to turn colourized terminal output by calling
322 ``pprint(..., with_colours=True)``. You will need
323 `termcolor package <https://pypi.org/project/termcolor/>`__
329 * Fixed invalid offset calculation when dealing with DEFINED BY objects
336 * BIT STRINGs can also be :ref:`DEFINED BY <definedby>`
337 * Decoding process can be governed with optional :ref:`ctx <ctx>`
338 keyword argument to ``decode()`` method
339 * :ref:`defines_by_path <defines_by_path_ctx>` option is now
340 :ref:`decode context <ctx>` option, not a keyword argument
341 * Ability to do ``strict validation``
342 of defaulted values met in sequence, raising an exception
348 Ability to skip specified number of bytes (``--skip``) in command line
355 * Generic decoder's schema and pretty printer
356 (:py:func:`pyderasn.generic_decoder`) can be used in libraries
357 * Ability to specify :ref:`defines_by_path <defines_by_path_ctx>`
358 during command line invocation
364 Ability to automatically decode :ref:`DEFINED BY <definedby>` fields
371 Removed ``__lt__``/``__eq__`` from base class, as pylint likes it.
377 Full rich comparison operators added.
384 Trivial README addition.
