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
14 * Initial support for so called ``evgen_mode``: event generation mode,
15 where no in-memory objects storing happens, giving ability to process
16 ASN.1 data without fully parsing it first
22 * Fixed workability under Python 3.5. Previously only 2.7 and 3.6
29 * Python ``int()``'s accepts even more various non-decimal characters
30 than expected. Make validation fully strict in UTCTime and
31 GeneralizedTime, without relying on ``int()``
37 * UTCTime and GeneralizedTime allowed values to have plus sign in them,
38 passing int() check successfully. Prohibit that incorrect behaviour
39 * UTCTime and GeneralizedTime BER decoding support
40 * Faster UTCTime and GeneralizedTime decoding, and slightly better
42 * Workability under Cython
43 * Explicitly Check that all ObjectIdentifier arcs are non-negative
49 * ``.copy()`` method removed: ``copy.copy()`` is preferred way to copy
51 * Copies made previously with ``.copy()`` lacked ``.defined`` field,
53 * All objects are friendly to ``pickle`` libraries
54 * PrintableString has ``allow_asterisk`` and ``allow_ampersand``
56 * ``.hexencode()``, ``.hexdecode()`` and ``.hexdecod()`` methods
57 appeared, working with hexadecimal encoded data
63 * Convenient ``.decod()`` method, that raises if tail is not empty
64 * Control characters (like newlines) of text fields in pprinted output
66 * Ability to allow asterisk and ampersand characters
67 (``allow_asterisk``, ``allow_ampersand`` kwargs) in PrintableString,
68 that unfortunately could be met in X.509 certificates
74 * PEP-396 compatible module's ``__version__``
80 * Do not shadow underlying DecodeError during decoding of optional
87 * Forbid any later GNU GPL version autousage (project's licence now is
89 * Fix ``defines_by_path`` context option usage example
95 * Fix fallbacked ``colored()`` function workability,
96 if no ``termcolor`` is installed
102 * Fix empty ``--oids`` workability
108 * Ability to specify multiple OID mappings for pprinted output
109 (``oids`` keyword argument is renamed to ``oid_maps``)
115 * Minor decode speed improvements
116 * Much faster UTCTime/GeneralizedTime decoders
117 * Stricter UTCTime/GeneralizedTime DER encoding check: trailing zeroes
119 * Valid DER encoding of GeneralizedTime with microseconds: no trailing
126 * ObjectIdentifier has ``ber_encoded`` set to True, if non-normalized
128 * Preserve BER-related attributes during ``copy()``
134 * Added `COMPLI <https://github.com/YuryStrozhevsky/asn1-test-suite>`__
135 ASN.1:2008 test suite. PyDERASN passes it (except for REAL values),
136 but it is more strict sometimes and aimed to be compliant with X.690-201508
137 * Check for arc values normalization in ObjectIdentifier.
138 Forbid non-normalized in DER encoding
144 * ``ctx`` parameter can be safely used in .decode() and won't be muted
145 * PP nametuple contains reference to the ASN1Obj itself
146 * ``colonize_hex`` function useful for pretty printing
147 * Integer values are also pretty printed in hexadecimal form
153 * All errors are inherited from ASN1Error class
154 * NumericString/PrintableString has ``allowable_chars`` property holding
155 all allowed characters
161 * Fix NumericString: space is allowed character
162 * Strict PrintableString sanitizing
168 * Removed ``lenindef``, ``ber_encoded`` attributes from the Choice --
169 they must be taken from underlying value, as Choice does not have its
171 * Do not yield extra EOC PP for Any, having indefinite length encoding
172 and containing autodecoded DEFINED BY value
178 * ``bered`` attribute, meaning if object has BER-specific encoding, is
179 renamed to ``ber_encoded``
180 * ``bered`` attribute is replace with property showing if any of
181 underlying values are BER-encoded. If value has length indefinite
182 encoded explicit tag, value, if value contains BER-related encoding,
183 or if it contains other objects that are ``bered``, then it is ``bered``
189 * Default value is checked also for Sets, not for Sequences only
190 * **Incompatible** change: defaulted values in Sequence/Set are always
191 strictly checked, unless ``allow_default_values`` context option is
192 set. ``strict_default_existence`` option disappeared
193 * Strict Set/Set Of's values ordering check
199 * Additional encoding validness check: explicit tag must contain exactly
200 one object inside. Throw DecodeError otherwise
201 * ``allow_expl_oob`` context and command-line options allow skipping of
208 * DecodeError's decode paths are separated with ``:``, instead of ``.``,
209 because of colliding with dots in OIDs
210 * Ability to print element decode paths with ``--print-decode-path``
211 command line option (and corresponding keyword argument)
212 * Ability to print tree's branch specified with ``--decode-path-only``
218 * Fix possible uncaught TypeError in Py2 with zero bytes inside the value
219 * Fix SequenceOf/SetOf raising BoundsError instead of DecodeError
225 * Fix uncaught UTCTime/GeneralizedTime decode error when dealing with
226 non ASCII-encoded values
232 * Fix long-standing bug with explicitly tagged objects inside the
233 Choice. If Choice had explicitly tagged value, then its ``.tlvlen``
234 reports the size without taking value's explicit tag in advance
235 * Add ``.fulllen`` and ``.fulloffset`` properties for all objects
241 * SEQUENCE's values are printed with field's name. Previously there was
242 the following output::
244 AlgorithmIdentifier SEQUENCE[OBJECT IDENTIFIER 1.3.14.3.2.26, [UNIV 5] ANY 0500 OPTIONAL]
248 AlgorithmIdentifier SEQUENCE[algorithm: OBJECT IDENTIFIER 1.3.14.3.2.26; parameters: [UNIV 5] ANY 0500 OPTIONAL]
249 * Fixed EOC (Unicode character) repr printing issues under Python2
255 BER's EOC is explicitly shown during pprinting. Following notation::
257 15-2 [0,0,1576]-4 . content: [0] EXPLICIT [UNIV 16] ANY
261 15-2∞ [0,0,1576]∞ . content: [0] EXPLICIT [UNIV 16] ANY
263 1587 [1,1, 0] . content: BER EOC
264 1589 [1,1, 0] . content: EXPLICIT BER EOC
270 * BER decoding support
271 * BitString's ''H notation support
272 * ``termcolor`` package is included in the tarball
278 * Ability to set values during Sequence initialization
284 * Fix TagMismatch exception completeness during Choice and Set decoding.
285 Previously we will loose offset and decode_path information about
286 concrete TagMismatched entity
292 * Strict NumericString's value sanitation
293 * Invalid encoding in string types will raise ``DecodeError`` exception,
294 instead of ``Unicode*Error``
295 * Fixed DecodePathDefBy workability with Python 2.x
301 * Fix nasty BitString decoding bug: it could fail when data follows
302 encoded BitString value. There weren't any problems when BitString is
303 at the end of Sequence
309 * Slightly corrected colours, now visible on white background
315 * Fix bug related to DecodeError showing with DecodePathDefBy entities
316 * Respect ``NO_COLOR`` environment variable
322 * :py:func:`pyderasn.decode_path_defby` is replaced with
323 :py:class:`pyderasn.DecodePathDefBy`
324 * Ability to turn colourized terminal output by calling
325 ``pprint(..., with_colours=True)``. You will need
326 `termcolor package <https://pypi.org/project/termcolor/>`__
332 * Fixed invalid offset calculation when dealing with DEFINED BY objects
339 * BIT STRINGs can also be :ref:`DEFINED BY <definedby>`
340 * Decoding process can be governed with optional :ref:`ctx <ctx>`
341 keyword argument to ``decode()`` method
342 * :ref:`defines_by_path <defines_by_path_ctx>` option is now
343 :ref:`decode context <ctx>` option, not a keyword argument
344 * Ability to do ``strict validation``
345 of defaulted values met in sequence, raising an exception
351 Ability to skip specified number of bytes (``--skip``) in command line
358 * Generic decoder's schema and pretty printer
359 (:py:func:`pyderasn.generic_decoder`) can be used in libraries
360 * Ability to specify :ref:`defines_by_path <defines_by_path_ctx>`
361 during command line invocation
367 Ability to automatically decode :ref:`DEFINED BY <definedby>` fields
374 Removed ``__lt__``/``__eq__`` from base class, as pylint likes it.
380 Full rich comparison operators added.
387 Trivial README addition.
