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
19 * Initial experimental CER encoding mode, allowing streaming encoding of
20 the data directly to some writeable object
21 * Ability to use mmap-ed memoryviews to skip files loading to memory
27 * Fixed workability under Python 3.5. Previously only 2.7 and 3.6
34 * Python ``int()``'s accepts even more various non-decimal characters
35 than expected. Make validation fully strict in UTCTime and
36 GeneralizedTime, without relying on ``int()``
42 * UTCTime and GeneralizedTime allowed values to have plus sign in them,
43 passing int() check successfully. Prohibit that incorrect behaviour
44 * UTCTime and GeneralizedTime BER decoding support
45 * Faster UTCTime and GeneralizedTime decoding, and slightly better
47 * Workability under Cython
48 * Explicitly Check that all ObjectIdentifier arcs are non-negative
54 * ``.copy()`` method removed: ``copy.copy()`` is preferred way to copy
56 * Copies made previously with ``.copy()`` lacked ``.defined`` field,
58 * All objects are friendly to ``pickle`` libraries
59 * PrintableString has ``allow_asterisk`` and ``allow_ampersand``
61 * ``.hexencode()``, ``.hexdecode()`` and ``.hexdecod()`` methods
62 appeared, working with hexadecimal encoded data
68 * Convenient ``.decod()`` method, that raises if tail is not empty
69 * Control characters (like newlines) of text fields in pprinted output
71 * Ability to allow asterisk and ampersand characters
72 (``allow_asterisk``, ``allow_ampersand`` kwargs) in PrintableString,
73 that unfortunately could be met in X.509 certificates
79 * PEP-396 compatible module's ``__version__``
85 * Do not shadow underlying DecodeError during decoding of optional
92 * Forbid any later GNU GPL version autousage (project's licence now is
94 * Fix ``defines_by_path`` context option usage example
100 * Fix fallbacked ``colored()`` function workability,
101 if no ``termcolor`` is installed
107 * Fix empty ``--oids`` workability
113 * Ability to specify multiple OID mappings for pprinted output
114 (``oids`` keyword argument is renamed to ``oid_maps``)
120 * Minor decode speed improvements
121 * Much faster UTCTime/GeneralizedTime decoders
122 * Stricter UTCTime/GeneralizedTime DER encoding check: trailing zeroes
124 * Valid DER encoding of GeneralizedTime with microseconds: no trailing
131 * ObjectIdentifier has ``ber_encoded`` set to True, if non-normalized
133 * Preserve BER-related attributes during ``copy()``
139 * Added `COMPLI <https://github.com/YuryStrozhevsky/asn1-test-suite>`__
140 ASN.1:2008 test suite. PyDERASN passes it (except for REAL values),
141 but it is more strict sometimes and aimed to be compliant with X.690-201508
142 * Check for arc values normalization in ObjectIdentifier.
143 Forbid non-normalized in DER encoding
149 * ``ctx`` parameter can be safely used in .decode() and won't be muted
150 * PP nametuple contains reference to the ASN1Obj itself
151 * ``colonize_hex`` function useful for pretty printing
152 * Integer values are also pretty printed in hexadecimal form
158 * All errors are inherited from ASN1Error class
159 * NumericString/PrintableString has ``allowable_chars`` property holding
160 all allowed characters
166 * Fix NumericString: space is allowed character
167 * Strict PrintableString sanitizing
173 * Removed ``lenindef``, ``ber_encoded`` attributes from the Choice --
174 they must be taken from underlying value, as Choice does not have its
176 * Do not yield extra EOC PP for Any, having indefinite length encoding
177 and containing autodecoded DEFINED BY value
183 * ``bered`` attribute, meaning if object has BER-specific encoding, is
184 renamed to ``ber_encoded``
185 * ``bered`` attribute is replace with property showing if any of
186 underlying values are BER-encoded. If value has length indefinite
187 encoded explicit tag, value, if value contains BER-related encoding,
188 or if it contains other objects that are ``bered``, then it is ``bered``
194 * Default value is checked also for Sets, not for Sequences only
195 * **Incompatible** change: defaulted values in Sequence/Set are always
196 strictly checked, unless ``allow_default_values`` context option is
197 set. ``strict_default_existence`` option disappeared
198 * Strict Set/Set Of's values ordering check
204 * Additional encoding validness check: explicit tag must contain exactly
205 one object inside. Throw DecodeError otherwise
206 * ``allow_expl_oob`` context and command-line options allow skipping of
213 * DecodeError's decode paths are separated with ``:``, instead of ``.``,
214 because of colliding with dots in OIDs
215 * Ability to print element decode paths with ``--print-decode-path``
216 command line option (and corresponding keyword argument)
217 * Ability to print tree's branch specified with ``--decode-path-only``
223 * Fix possible uncaught TypeError in Py2 with zero bytes inside the value
224 * Fix SequenceOf/SetOf raising BoundsError instead of DecodeError
230 * Fix uncaught UTCTime/GeneralizedTime decode error when dealing with
231 non ASCII-encoded values
237 * Fix long-standing bug with explicitly tagged objects inside the
238 Choice. If Choice had explicitly tagged value, then its ``.tlvlen``
239 reports the size without taking value's explicit tag in advance
240 * Add ``.fulllen`` and ``.fulloffset`` properties for all objects
246 * SEQUENCE's values are printed with field's name. Previously there was
247 the following output::
249 AlgorithmIdentifier SEQUENCE[OBJECT IDENTIFIER 1.3.14.3.2.26, [UNIV 5] ANY 0500 OPTIONAL]
253 AlgorithmIdentifier SEQUENCE[algorithm: OBJECT IDENTIFIER 1.3.14.3.2.26; parameters: [UNIV 5] ANY 0500 OPTIONAL]
254 * Fixed EOC (Unicode character) repr printing issues under Python2
260 BER's EOC is explicitly shown during pprinting. Following notation::
262 15-2 [0,0,1576]-4 . content: [0] EXPLICIT [UNIV 16] ANY
266 15-2∞ [0,0,1576]∞ . content: [0] EXPLICIT [UNIV 16] ANY
268 1587 [1,1, 0] . content: BER EOC
269 1589 [1,1, 0] . content: EXPLICIT BER EOC
275 * BER decoding support
276 * BitString's ''H notation support
277 * ``termcolor`` package is included in the tarball
283 * Ability to set values during Sequence initialization
289 * Fix TagMismatch exception completeness during Choice and Set decoding.
290 Previously we will loose offset and decode_path information about
291 concrete TagMismatched entity
297 * Strict NumericString's value sanitation
298 * Invalid encoding in string types will raise ``DecodeError`` exception,
299 instead of ``Unicode*Error``
300 * Fixed DecodePathDefBy workability with Python 2.x
306 * Fix nasty BitString decoding bug: it could fail when data follows
307 encoded BitString value. There weren't any problems when BitString is
308 at the end of Sequence
314 * Slightly corrected colours, now visible on white background
320 * Fix bug related to DecodeError showing with DecodePathDefBy entities
321 * Respect ``NO_COLOR`` environment variable
327 * :py:func:`pyderasn.decode_path_defby` is replaced with
328 :py:class:`pyderasn.DecodePathDefBy`
329 * Ability to turn colourized terminal output by calling
330 ``pprint(..., with_colours=True)``. You will need
331 `termcolor package <https://pypi.org/project/termcolor/>`__
337 * Fixed invalid offset calculation when dealing with DEFINED BY objects
344 * BIT STRINGs can also be :ref:`DEFINED BY <definedby>`
345 * Decoding process can be governed with optional :ref:`ctx <ctx>`
346 keyword argument to ``decode()`` method
347 * :ref:`defines_by_path <defines_by_path_ctx>` option is now
348 :ref:`decode context <ctx>` option, not a keyword argument
349 * Ability to do ``strict validation``
350 of defaulted values met in sequence, raising an exception
356 Ability to skip specified number of bytes (``--skip``) in command line
363 * Generic decoder's schema and pretty printer
364 (:py:func:`pyderasn.generic_decoder`) can be used in libraries
365 * Ability to specify :ref:`defines_by_path <defines_by_path_ctx>`
366 during command line invocation
372 Ability to automatically decode :ref:`DEFINED BY <definedby>` fields
379 Removed ``__lt__``/``__eq__`` from base class, as pylint likes it.
385 Full rich comparison operators added.
392 Trivial README addition.
