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 * Useful ``agg_octet_string`` that is able to streamingly decode string
21 from events of ``evgen_mode``, allowing strings retrieving without
22 copying them to memory first
23 * Initial experimental CER encoding mode, allowing streaming encoding of
24 the data directly to some writeable object
25 * Ability to use mmap-ed memoryviews to skip files loading to memory
31 * Fixed workability under Python 3.5. Previously only 2.7 and 3.6
38 * Python ``int()``'s accepts even more various non-decimal characters
39 than expected. Make validation fully strict in UTCTime and
40 GeneralizedTime, without relying on ``int()``
46 * UTCTime and GeneralizedTime allowed values to have plus sign in them,
47 passing int() check successfully. Prohibit that incorrect behaviour
48 * UTCTime and GeneralizedTime BER decoding support
49 * Faster UTCTime and GeneralizedTime decoding, and slightly better
51 * Workability under Cython
52 * Explicitly Check that all ObjectIdentifier arcs are non-negative
58 * ``.copy()`` method removed: ``copy.copy()`` is preferred way to copy
60 * Copies made previously with ``.copy()`` lacked ``.defined`` field,
62 * All objects are friendly to ``pickle`` libraries
63 * PrintableString has ``allow_asterisk`` and ``allow_ampersand``
65 * ``.hexencode()``, ``.hexdecode()`` and ``.hexdecod()`` methods
66 appeared, working with hexadecimal encoded data
72 * Convenient ``.decod()`` method, that raises if tail is not empty
73 * Control characters (like newlines) of text fields in pprinted output
75 * Ability to allow asterisk and ampersand characters
76 (``allow_asterisk``, ``allow_ampersand`` kwargs) in PrintableString,
77 that unfortunately could be met in X.509 certificates
83 * PEP-396 compatible module's ``__version__``
89 * Do not shadow underlying DecodeError during decoding of optional
96 * Forbid any later GNU GPL version autousage (project's licence now is
98 * Fix ``defines_by_path`` context option usage example
104 * Fix fallbacked ``colored()`` function workability,
105 if no ``termcolor`` is installed
111 * Fix empty ``--oids`` workability
117 * Ability to specify multiple OID mappings for pprinted output
118 (``oids`` keyword argument is renamed to ``oid_maps``)
124 * Minor decode speed improvements
125 * Much faster UTCTime/GeneralizedTime decoders
126 * Stricter UTCTime/GeneralizedTime DER encoding check: trailing zeroes
128 * Valid DER encoding of GeneralizedTime with microseconds: no trailing
135 * ObjectIdentifier has ``ber_encoded`` set to True, if non-normalized
137 * Preserve BER-related attributes during ``copy()``
143 * Added `COMPLI <https://github.com/YuryStrozhevsky/asn1-test-suite>`__
144 ASN.1:2008 test suite. PyDERASN passes it (except for REAL values),
145 but it is more strict sometimes and aimed to be compliant with X.690-201508
146 * Check for arc values normalization in ObjectIdentifier.
147 Forbid non-normalized in DER encoding
153 * ``ctx`` parameter can be safely used in .decode() and won't be muted
154 * PP nametuple contains reference to the ASN1Obj itself
155 * ``colonize_hex`` function useful for pretty printing
156 * Integer values are also pretty printed in hexadecimal form
162 * All errors are inherited from ASN1Error class
163 * NumericString/PrintableString has ``allowable_chars`` property holding
164 all allowed characters
170 * Fix NumericString: space is allowed character
171 * Strict PrintableString sanitizing
177 * Removed ``lenindef``, ``ber_encoded`` attributes from the Choice --
178 they must be taken from underlying value, as Choice does not have its
180 * Do not yield extra EOC PP for Any, having indefinite length encoding
181 and containing autodecoded DEFINED BY value
187 * ``bered`` attribute, meaning if object has BER-specific encoding, is
188 renamed to ``ber_encoded``
189 * ``bered`` attribute is replace with property showing if any of
190 underlying values are BER-encoded. If value has length indefinite
191 encoded explicit tag, value, if value contains BER-related encoding,
192 or if it contains other objects that are ``bered``, then it is ``bered``
198 * Default value is checked also for Sets, not for Sequences only
199 * **Incompatible** change: defaulted values in Sequence/Set are always
200 strictly checked, unless ``allow_default_values`` context option is
201 set. ``strict_default_existence`` option disappeared
202 * Strict Set/Set Of's values ordering check
208 * Additional encoding validness check: explicit tag must contain exactly
209 one object inside. Throw DecodeError otherwise
210 * ``allow_expl_oob`` context and command-line options allow skipping of
217 * DecodeError's decode paths are separated with ``:``, instead of ``.``,
218 because of colliding with dots in OIDs
219 * Ability to print element decode paths with ``--print-decode-path``
220 command line option (and corresponding keyword argument)
221 * Ability to print tree's branch specified with ``--decode-path-only``
227 * Fix possible uncaught TypeError in Py2 with zero bytes inside the value
228 * Fix SequenceOf/SetOf raising BoundsError instead of DecodeError
234 * Fix uncaught UTCTime/GeneralizedTime decode error when dealing with
235 non ASCII-encoded values
241 * Fix long-standing bug with explicitly tagged objects inside the
242 Choice. If Choice had explicitly tagged value, then its ``.tlvlen``
243 reports the size without taking value's explicit tag in advance
244 * Add ``.fulllen`` and ``.fulloffset`` properties for all objects
250 * SEQUENCE's values are printed with field's name. Previously there was
251 the following output::
253 AlgorithmIdentifier SEQUENCE[OBJECT IDENTIFIER 1.3.14.3.2.26, [UNIV 5] ANY 0500 OPTIONAL]
257 AlgorithmIdentifier SEQUENCE[algorithm: OBJECT IDENTIFIER 1.3.14.3.2.26; parameters: [UNIV 5] ANY 0500 OPTIONAL]
258 * Fixed EOC (Unicode character) repr printing issues under Python2
264 BER's EOC is explicitly shown during pprinting. Following notation::
266 15-2 [0,0,1576]-4 . content: [0] EXPLICIT [UNIV 16] ANY
270 15-2∞ [0,0,1576]∞ . content: [0] EXPLICIT [UNIV 16] ANY
272 1587 [1,1, 0] . content: BER EOC
273 1589 [1,1, 0] . content: EXPLICIT BER EOC
279 * BER decoding support
280 * BitString's ''H notation support
281 * ``termcolor`` package is included in the tarball
287 * Ability to set values during Sequence initialization
293 * Fix TagMismatch exception completeness during Choice and Set decoding.
294 Previously we will loose offset and decode_path information about
295 concrete TagMismatched entity
301 * Strict NumericString's value sanitation
302 * Invalid encoding in string types will raise ``DecodeError`` exception,
303 instead of ``Unicode*Error``
304 * Fixed DecodePathDefBy workability with Python 2.x
310 * Fix nasty BitString decoding bug: it could fail when data follows
311 encoded BitString value. There weren't any problems when BitString is
312 at the end of Sequence
318 * Slightly corrected colours, now visible on white background
324 * Fix bug related to DecodeError showing with DecodePathDefBy entities
325 * Respect ``NO_COLOR`` environment variable
331 * :py:func:`pyderasn.decode_path_defby` is replaced with
332 :py:class:`pyderasn.DecodePathDefBy`
333 * Ability to turn colourized terminal output by calling
334 ``pprint(..., with_colours=True)``. You will need
335 `termcolor package <https://pypi.org/project/termcolor/>`__
341 * Fixed invalid offset calculation when dealing with DEFINED BY objects
348 * BIT STRINGs can also be :ref:`DEFINED BY <definedby>`
349 * Decoding process can be governed with optional :ref:`ctx <ctx>`
350 keyword argument to ``decode()`` method
351 * :ref:`defines_by_path <defines_by_path_ctx>` option is now
352 :ref:`decode context <ctx>` option, not a keyword argument
353 * Ability to do ``strict validation``
354 of defaulted values met in sequence, raising an exception
360 Ability to skip specified number of bytes (``--skip``) in command line
367 * Generic decoder's schema and pretty printer
368 (:py:func:`pyderasn.generic_decoder`) can be used in libraries
369 * Ability to specify :ref:`defines_by_path <defines_by_path_ctx>`
370 during command line invocation
376 Ability to automatically decode :ref:`DEFINED BY <definedby>` fields
383 Removed ``__lt__``/``__eq__`` from base class, as pylint likes it.
389 Full rich comparison operators added.
396 Trivial README addition.
