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
26 * Ability to use memoryview as an input for \*Strings. If they are
27 mmap-ed, then you can encode any quantities of data streamingly
28 without copying to memory
34 * Fixed workability under Python 3.5. Previously only 2.7 and 3.6
41 * Python ``int()``'s accepts even more various non-decimal characters
42 than expected. Make validation fully strict in UTCTime and
43 GeneralizedTime, without relying on ``int()``
49 * UTCTime and GeneralizedTime allowed values to have plus sign in them,
50 passing int() check successfully. Prohibit that incorrect behaviour
51 * UTCTime and GeneralizedTime BER decoding support
52 * Faster UTCTime and GeneralizedTime decoding, and slightly better
54 * Workability under Cython
55 * Explicitly Check that all ObjectIdentifier arcs are non-negative
61 * ``.copy()`` method removed: ``copy.copy()`` is preferred way to copy
63 * Copies made previously with ``.copy()`` lacked ``.defined`` field,
65 * All objects are friendly to ``pickle`` libraries
66 * PrintableString has ``allow_asterisk`` and ``allow_ampersand``
68 * ``.hexencode()``, ``.hexdecode()`` and ``.hexdecod()`` methods
69 appeared, working with hexadecimal encoded data
75 * Convenient ``.decod()`` method, that raises if tail is not empty
76 * Control characters (like newlines) of text fields in pprinted output
78 * Ability to allow asterisk and ampersand characters
79 (``allow_asterisk``, ``allow_ampersand`` kwargs) in PrintableString,
80 that unfortunately could be met in X.509 certificates
86 * PEP-396 compatible module's ``__version__``
92 * Do not shadow underlying DecodeError during decoding of optional
99 * Forbid any later GNU GPL version autousage (project's licence now is
101 * Fix ``defines_by_path`` context option usage example
107 * Fix fallbacked ``colored()`` function workability,
108 if no ``termcolor`` is installed
114 * Fix empty ``--oids`` workability
120 * Ability to specify multiple OID mappings for pprinted output
121 (``oids`` keyword argument is renamed to ``oid_maps``)
127 * Minor decode speed improvements
128 * Much faster UTCTime/GeneralizedTime decoders
129 * Stricter UTCTime/GeneralizedTime DER encoding check: trailing zeroes
131 * Valid DER encoding of GeneralizedTime with microseconds: no trailing
138 * ObjectIdentifier has ``ber_encoded`` set to True, if non-normalized
140 * Preserve BER-related attributes during ``copy()``
146 * Added `COMPLI <https://github.com/YuryStrozhevsky/asn1-test-suite>`__
147 ASN.1:2008 test suite. PyDERASN passes it (except for REAL values),
148 but it is more strict sometimes and aimed to be compliant with X.690-201508
149 * Check for arc values normalization in ObjectIdentifier.
150 Forbid non-normalized in DER encoding
156 * ``ctx`` parameter can be safely used in .decode() and won't be muted
157 * PP nametuple contains reference to the ASN1Obj itself
158 * ``colonize_hex`` function useful for pretty printing
159 * Integer values are also pretty printed in hexadecimal form
165 * All errors are inherited from ASN1Error class
166 * NumericString/PrintableString has ``allowable_chars`` property holding
167 all allowed characters
173 * Fix NumericString: space is allowed character
174 * Strict PrintableString sanitizing
180 * Removed ``lenindef``, ``ber_encoded`` attributes from the Choice --
181 they must be taken from underlying value, as Choice does not have its
183 * Do not yield extra EOC PP for Any, having indefinite length encoding
184 and containing autodecoded DEFINED BY value
190 * ``bered`` attribute, meaning if object has BER-specific encoding, is
191 renamed to ``ber_encoded``
192 * ``bered`` attribute is replace with property showing if any of
193 underlying values are BER-encoded. If value has length indefinite
194 encoded explicit tag, value, if value contains BER-related encoding,
195 or if it contains other objects that are ``bered``, then it is ``bered``
201 * Default value is checked also for Sets, not for Sequences only
202 * **Incompatible** change: defaulted values in Sequence/Set are always
203 strictly checked, unless ``allow_default_values`` context option is
204 set. ``strict_default_existence`` option disappeared
205 * Strict Set/Set Of's values ordering check
211 * Additional encoding validness check: explicit tag must contain exactly
212 one object inside. Throw DecodeError otherwise
213 * ``allow_expl_oob`` context and command-line options allow skipping of
220 * DecodeError's decode paths are separated with ``:``, instead of ``.``,
221 because of colliding with dots in OIDs
222 * Ability to print element decode paths with ``--print-decode-path``
223 command line option (and corresponding keyword argument)
224 * Ability to print tree's branch specified with ``--decode-path-only``
230 * Fix possible uncaught TypeError in Py2 with zero bytes inside the value
231 * Fix SequenceOf/SetOf raising BoundsError instead of DecodeError
237 * Fix uncaught UTCTime/GeneralizedTime decode error when dealing with
238 non ASCII-encoded values
244 * Fix long-standing bug with explicitly tagged objects inside the
245 Choice. If Choice had explicitly tagged value, then its ``.tlvlen``
246 reports the size without taking value's explicit tag in advance
247 * Add ``.fulllen`` and ``.fulloffset`` properties for all objects
253 * SEQUENCE's values are printed with field's name. Previously there was
254 the following output::
256 AlgorithmIdentifier SEQUENCE[OBJECT IDENTIFIER 1.3.14.3.2.26, [UNIV 5] ANY 0500 OPTIONAL]
260 AlgorithmIdentifier SEQUENCE[algorithm: OBJECT IDENTIFIER 1.3.14.3.2.26; parameters: [UNIV 5] ANY 0500 OPTIONAL]
261 * Fixed EOC (Unicode character) repr printing issues under Python2
267 BER's EOC is explicitly shown during pprinting. Following notation::
269 15-2 [0,0,1576]-4 . content: [0] EXPLICIT [UNIV 16] ANY
273 15-2∞ [0,0,1576]∞ . content: [0] EXPLICIT [UNIV 16] ANY
275 1587 [1,1, 0] . content: BER EOC
276 1589 [1,1, 0] . content: EXPLICIT BER EOC
282 * BER decoding support
283 * BitString's ''H notation support
284 * ``termcolor`` package is included in the tarball
290 * Ability to set values during Sequence initialization
296 * Fix TagMismatch exception completeness during Choice and Set decoding.
297 Previously we will loose offset and decode_path information about
298 concrete TagMismatched entity
304 * Strict NumericString's value sanitation
305 * Invalid encoding in string types will raise ``DecodeError`` exception,
306 instead of ``Unicode*Error``
307 * Fixed DecodePathDefBy workability with Python 2.x
313 * Fix nasty BitString decoding bug: it could fail when data follows
314 encoded BitString value. There weren't any problems when BitString is
315 at the end of Sequence
321 * Slightly corrected colours, now visible on white background
327 * Fix bug related to DecodeError showing with DecodePathDefBy entities
328 * Respect ``NO_COLOR`` environment variable
334 * :py:func:`pyderasn.decode_path_defby` is replaced with
335 :py:class:`pyderasn.DecodePathDefBy`
336 * Ability to turn colourized terminal output by calling
337 ``pprint(..., with_colours=True)``. You will need
338 `termcolor package <https://pypi.org/project/termcolor/>`__
344 * Fixed invalid offset calculation when dealing with DEFINED BY objects
351 * BIT STRINGs can also be :ref:`DEFINED BY <definedby>`
352 * Decoding process can be governed with optional :ref:`ctx <ctx>`
353 keyword argument to ``decode()`` method
354 * :ref:`defines_by_path <defines_by_path_ctx>` option is now
355 :ref:`decode context <ctx>` option, not a keyword argument
356 * Ability to do ``strict validation``
357 of defaulted values met in sequence, raising an exception
363 Ability to skip specified number of bytes (``--skip``) in command line
370 * Generic decoder's schema and pretty printer
371 (:py:func:`pyderasn.generic_decoder`) can be used in libraries
372 * Ability to specify :ref:`defines_by_path <defines_by_path_ctx>`
373 during command line invocation
379 Ability to automatically decode :ref:`DEFINED BY <definedby>` fields
386 Removed ``__lt__``/``__eq__`` from base class, as pylint likes it.
392 Full rich comparison operators added.
399 Trivial README addition.
