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 * ``SetOf`` is not treated as ready, if no value was set and minimum
15 bounds are greater than zero
16 * ``Any`` allows an ordinary ``Obj`` storing, without its forceful
17 encoded representation storage
18 * Initial support for so called ``evgen_mode``: event generation mode,
19 where no in-memory objects storing happens, giving ability to process
20 ASN.1 data without fully parsing it first. ``python -m pyderasn`` has
21 ``--evgen`` mode switcher
22 * Useful ``agg_octet_string`` that is able to streamingly decode string
23 from events of ``evgen_mode``, allowing strings retrieving without
24 copying them to memory first
25 * Initial experimental CER encoding mode, allowing streaming encoding of
26 the data directly to some writeable object
27 * Ability to use mmap-ed memoryviews to skip files loading to memory
28 * Ability to use memoryview as an input for \*Strings. If they are
29 mmap-ed, then you can encode any quantities of data streamingly
30 without copying to memory
36 * Fixed workability under Python 3.5. Previously only 2.7 and 3.6
43 * Python ``int()``'s accepts even more various non-decimal characters
44 than expected. Make validation fully strict in UTCTime and
45 GeneralizedTime, without relying on ``int()``
51 * UTCTime and GeneralizedTime allowed values to have plus sign in them,
52 passing int() check successfully. Prohibit that incorrect behaviour
53 * UTCTime and GeneralizedTime BER decoding support
54 * Faster UTCTime and GeneralizedTime decoding, and slightly better
56 * Workability under Cython
57 * Explicitly Check that all ObjectIdentifier arcs are non-negative
63 * ``.copy()`` method removed: ``copy.copy()`` is preferred way to copy
65 * Copies made previously with ``.copy()`` lacked ``.defined`` field,
67 * All objects are friendly to ``pickle`` libraries
68 * PrintableString has ``allow_asterisk`` and ``allow_ampersand``
70 * ``.hexencode()``, ``.hexdecode()`` and ``.hexdecod()`` methods
71 appeared, working with hexadecimal encoded data
77 * Convenient ``.decod()`` method, that raises if tail is not empty
78 * Control characters (like newlines) of text fields in pprinted output
80 * Ability to allow asterisk and ampersand characters
81 (``allow_asterisk``, ``allow_ampersand`` kwargs) in PrintableString,
82 that unfortunately could be met in X.509 certificates
88 * PEP-396 compatible module's ``__version__``
94 * Do not shadow underlying DecodeError during decoding of optional
101 * Forbid any later GNU GPL version autousage (project's licence now is
103 * Fix ``defines_by_path`` context option usage example
109 * Fix fallbacked ``colored()`` function workability,
110 if no ``termcolor`` is installed
116 * Fix empty ``--oids`` workability
122 * Ability to specify multiple OID mappings for pprinted output
123 (``oids`` keyword argument is renamed to ``oid_maps``)
129 * Minor decode speed improvements
130 * Much faster UTCTime/GeneralizedTime decoders
131 * Stricter UTCTime/GeneralizedTime DER encoding check: trailing zeroes
133 * Valid DER encoding of GeneralizedTime with microseconds: no trailing
140 * ObjectIdentifier has ``ber_encoded`` set to True, if non-normalized
142 * Preserve BER-related attributes during ``copy()``
148 * Added `COMPLI <https://github.com/YuryStrozhevsky/asn1-test-suite>`__
149 ASN.1:2008 test suite. PyDERASN passes it (except for REAL values),
150 but it is more strict sometimes and aimed to be compliant with X.690-201508
151 * Check for arc values normalization in ObjectIdentifier.
152 Forbid non-normalized in DER encoding
158 * ``ctx`` parameter can be safely used in .decode() and won't be muted
159 * PP nametuple contains reference to the ASN1Obj itself
160 * ``colonize_hex`` function useful for pretty printing
161 * Integer values are also pretty printed in hexadecimal form
167 * All errors are inherited from ASN1Error class
168 * NumericString/PrintableString has ``allowable_chars`` property holding
169 all allowed characters
175 * Fix NumericString: space is allowed character
176 * Strict PrintableString sanitizing
182 * Removed ``lenindef``, ``ber_encoded`` attributes from the Choice --
183 they must be taken from underlying value, as Choice does not have its
185 * Do not yield extra EOC PP for Any, having indefinite length encoding
186 and containing autodecoded DEFINED BY value
192 * ``bered`` attribute, meaning if object has BER-specific encoding, is
193 renamed to ``ber_encoded``
194 * ``bered`` attribute is replace with property showing if any of
195 underlying values are BER-encoded. If value has length indefinite
196 encoded explicit tag, value, if value contains BER-related encoding,
197 or if it contains other objects that are ``bered``, then it is ``bered``
203 * Default value is checked also for Sets, not for Sequences only
204 * **Incompatible** change: defaulted values in Sequence/Set are always
205 strictly checked, unless ``allow_default_values`` context option is
206 set. ``strict_default_existence`` option disappeared
207 * Strict Set/Set Of's values ordering check
213 * Additional encoding validness check: explicit tag must contain exactly
214 one object inside. Throw DecodeError otherwise
215 * ``allow_expl_oob`` context and command-line options allow skipping of
222 * DecodeError's decode paths are separated with ``:``, instead of ``.``,
223 because of colliding with dots in OIDs
224 * Ability to print element decode paths with ``--print-decode-path``
225 command line option (and corresponding keyword argument)
226 * Ability to print tree's branch specified with ``--decode-path-only``
232 * Fix possible uncaught TypeError in Py2 with zero bytes inside the value
233 * Fix SequenceOf/SetOf raising BoundsError instead of DecodeError
239 * Fix uncaught UTCTime/GeneralizedTime decode error when dealing with
240 non ASCII-encoded values
246 * Fix long-standing bug with explicitly tagged objects inside the
247 Choice. If Choice had explicitly tagged value, then its ``.tlvlen``
248 reports the size without taking value's explicit tag in advance
249 * Add ``.fulllen`` and ``.fulloffset`` properties for all objects
255 * SEQUENCE's values are printed with field's name. Previously there was
256 the following output::
258 AlgorithmIdentifier SEQUENCE[OBJECT IDENTIFIER 1.3.14.3.2.26, [UNIV 5] ANY 0500 OPTIONAL]
262 AlgorithmIdentifier SEQUENCE[algorithm: OBJECT IDENTIFIER 1.3.14.3.2.26; parameters: [UNIV 5] ANY 0500 OPTIONAL]
263 * Fixed EOC (Unicode character) repr printing issues under Python2
269 BER's EOC is explicitly shown during pprinting. Following notation::
271 15-2 [0,0,1576]-4 . content: [0] EXPLICIT [UNIV 16] ANY
275 15-2∞ [0,0,1576]∞ . content: [0] EXPLICIT [UNIV 16] ANY
277 1587 [1,1, 0] . content: BER EOC
278 1589 [1,1, 0] . content: EXPLICIT BER EOC
284 * BER decoding support
285 * BitString's ''H notation support
286 * ``termcolor`` package is included in the tarball
292 * Ability to set values during Sequence initialization
298 * Fix TagMismatch exception completeness during Choice and Set decoding.
299 Previously we will loose offset and decode_path information about
300 concrete TagMismatched entity
306 * Strict NumericString's value sanitation
307 * Invalid encoding in string types will raise ``DecodeError`` exception,
308 instead of ``Unicode*Error``
309 * Fixed DecodePathDefBy workability with Python 2.x
315 * Fix nasty BitString decoding bug: it could fail when data follows
316 encoded BitString value. There weren't any problems when BitString is
317 at the end of Sequence
323 * Slightly corrected colours, now visible on white background
329 * Fix bug related to DecodeError showing with DecodePathDefBy entities
330 * Respect ``NO_COLOR`` environment variable
336 * :py:func:`pyderasn.decode_path_defby` is replaced with
337 :py:class:`pyderasn.DecodePathDefBy`
338 * Ability to turn colourized terminal output by calling
339 ``pprint(..., with_colours=True)``. You will need
340 `termcolor package <https://pypi.org/project/termcolor/>`__
346 * Fixed invalid offset calculation when dealing with DEFINED BY objects
353 * BIT STRINGs can also be :ref:`DEFINED BY <definedby>`
354 * Decoding process can be governed with optional :ref:`ctx <ctx>`
355 keyword argument to ``decode()`` method
356 * :ref:`defines_by_path <defines_by_path_ctx>` option is now
357 :ref:`decode context <ctx>` option, not a keyword argument
358 * Ability to do ``strict validation``
359 of defaulted values met in sequence, raising an exception
365 Ability to skip specified number of bytes (``--skip``) in command line
372 * Generic decoder's schema and pretty printer
373 (:py:func:`pyderasn.generic_decoder`) can be used in libraries
374 * Ability to specify :ref:`defines_by_path <defines_by_path_ctx>`
375 during command line invocation
381 Ability to automatically decode :ref:`DEFINED BY <definedby>` fields
388 Removed ``__lt__``/``__eq__`` from base class, as pylint likes it.
394 Full rich comparison operators added.
401 Trivial README addition.
